  Before WOOD, Chief Judge, and EASTERBROOK and
WILLIAMS, Circuit Judges.
    WOOD, Chief Judge. Tina Ewell was a close friend and con-
fidante of her sister, Eve Nance. So close, in fact, that when
Nance shot and killed her husband, Ewell helped Nance dis-
pose of his body. For this, a Wisconsin court convicted Ewell
of a number of felony and misdemeanor charges in October
2016. But she is not asking us to second-guess those convic-
2                                                   No. 16-1009

tions. Instead, she is complaining about an aspect of the crim-
inal investigation—namely, her initial arrest and detention
immediately after the murder. During the period between her
release from that detention and her indictment in the criminal
case, she filed a civil rights action complaining that the deten-
tion was not supported by probable cause but was instead for
the impermissible goal of building a case against her. Resolv-
ing the case before the state criminal proceeding began, the
district court dismissed her suit, and this appeal followed. Be-
cause we conclude that Ewell is not entitled to damages on
most of her claims, and that the defendants are entitled to
qualified immunity on the rest, we affirm.
                                I
    Eve Nance shot and killed her husband, Timothy Nance,
as he stood in the shower of their Fond du Lac, Wisconsin,
home on November 1, 2013. Four days later, Nance reported
him missing. Two detectives from the Fond du Lac Police De-
partment, William Ledger and Matt Bobo (“the detectives”),
were assigned to investigate. What follows is their account of
their actions. They began by interviewing Timothy’s family,
his new girlfriend, and various friends, including Ewell. Some
of those friends told them about the Nance couple’s fraught
history of threats and violence, including recent discord over
Timothy’s new girlfriend and his purported plan to divorce
Nance. The detectives also said that a witness had noticed that
the shower curtain, liner, and hooks in the Nance bathroom
had been replaced after Timothy disappeared. Nance and her
daughter confirmed this detail, which one of the detectives
had observed independently.
    The detectives also reviewed surveillance tapes from a lo-
cal store. The tapes showed Ewell and Nance buying new
No. 16-1009                                                 3

shower curtain liners and hooks the night Timothy went miss-
ing. On November 20, the day after they reviewed the surveil-
lance tape, the detectives and crime lab technicians executed
a search warrant at the Nance house and seized “biological
specimens,” a “projectile” from the bathtub pipes, clothing,
and other evidence. That same day, the detectives spoke to
Ewell again. When they asked her to accompany them to the
police station for further questioning, she refused. They did
not take “no” for an answer: they arrested Ewell and trans-
ported her to the Fond du Lac police station sometime be-
tween 2 and 4 p.m.—approximately an hour after arresting
Eve Nance.
    Ewell asserted her right to remain silent, requested coun-
sel, and was moved to the Fond du Lac County Jail around
3:45 or 4 p.m. that same day. She spent the next two days in
custody. At 4:02 p.m. on November 22, Detective Ledger
signed a probable cause statement in front of a Fond du Lac
County judge. In that statement, Ledger reported that he be-
lieved that Timothy Nance was murdered, that the shower
curtain and liner had been used to conceal evidence of Timo-
thy’s death, and that Nance and Ewell had removed Timothy’s
body and concealed it in an unknown location. At 4:15 p.m.,
the judge, relying exclusively on Ledger’s statement and ac-
companying affidavit, determined that probable cause ex-
isted to detain Ewell and denied Ewell bond pending a court
appearance. Ewell’s public defender filed a habeas corpus pe-
tition on her behalf with the Fond du Lac County Circuit
Court on November 26. The following afternoon, the same
judge who had found probable cause on November 22 con-
ducted a hearing on the habeas corpus petition. At that hear-
ing, Ewell’s public defender contended that the November 22
4                                                    No. 16-1009

probable cause determination had occurred after the expira-
tion of the 48-hour period considered presumptively reason-
able under County of Riverside v. McLaughlin, 

(1991), and that there had not been an initial appearance or
the filing of a complaint within a reasonable time of arrest.
    The county judge agreed that the Riverside determination
was outside the 48-hour window, and so the burden shifted
to the state to show extraordinary circumstances. The state,
the judge decided, satisfied that burden, given the activity re-
lated to the case on the court calendar. The judge stated that
although Detective Ledger had contacted him earlier to sign
the statement, he (the judge) could not have diligently re-
viewed and signed it any earlier than he did. The judge then
reiterated his conclusion that probable cause existed to detain
Ewell. Immediately thereafter, the court held a bond hearing
and set a $50,000 cash bond for Ewell. The court was closed
from November 28 through December 1 for the Thanksgiving
holiday and weekend. On December 2, 2013, the Fond du Lac
County District Attorney, Eric Toney, requested Ewell’s re-
lease, and the state court ordered her release that same day.
At that point, the state had filed no charges against her; in all,
she had spent 12 days in custody.
    On August 4, 2014, Ewell filed a complaint in federal court
under 42 U.S.C. § 1983, alleging that the detectives and DA
Toney had arrested and held her without probable cause and
had conspired to deprive her of her constitutional rights by
false arrest and unlawful detention. The district court granted
the defendants’ motions to dismiss on January 4, 2016, finding
that some of Ewell’s allegations against DA Toney failed to
state a claim and that he was entitled to qualified immunity
on the remaining claims; that the detectives were entitled to
No. 16-1009                                                    5

qualified immunity because probable cause existed to arrest
Ewell; and that, on the understanding that her complaint al-
leged a conspiracy to interfere with her civil rights in a man-
ner prohibited by 42 U.S.C. § 1985, Ewell failed to state a claim
because she had not named any private actors. Ewell filed a
timely notice of appeal from the court’s final judgment on Jan-
uary 8, 2016.
    While her appeal was pending before our court, the Fond
du Lac District Attorney filed charges against Ewell on April
12, 2016. See Wisconsin v. Tina M. Ewell, Fond du Lac County
Case No. 2016-CF-231. She was accused of committing four
crimes: (1) felony hiding a corpse, Wis. Stat. Ann. § 940.11(2);
(2) felony harboring or aiding a felony, Wis. Stat. Ann.
§ 946.47(1)(b); (3) misdemeanor resisting or obstructing an of-
ficer, Wis. Stat. Ann. § 946.41(1); and (4) misdemeanor failure
to report a death under unusual or suspicious circumstances,
Wis. Stat. Ann. § 979.01(1)(a). After those charges were filed,
the detectives moved this court to stay the appellate proceed-
ings in her civil rights case, arguing that Younger abstention
was appropriate. We denied that motion and invited the de-
tectives to address Younger in their responsive brief. On Octo-
ber 28, 2016, prior to oral arguments before our court, a state
jury found Ewell guilty of the first three counts. (The prose-
cutor had dismissed the fourth count a few days earlier.) The
detectives again asked us to dismiss the proceedings, this time
on the basis of both Younger abstention and the bar established
in Heck v. Humphrey, 

(1994). We ordered this mo-
tion to be taken with the case for resolution after oral argu-
ment. On December 8, 2016—six days after we heard oral ar-
gument on her appeal—the state court sentenced Ewell to two
years’ imprisonment.

                                II
   Simultaneous state and federal court cases relating to the
same events pose important questions relating to federal-state
comity. These are not jurisdictional questions, but the defend-
ants have properly raised them, and they should be resolved
before we push on to the merits.
                                A
     The Younger abstention doctrine, which is rooted in tradi-
tional principles of equity, comity, and federalism, requires
federal courts to refrain from exercising their jurisdiction
when relief may interfere with certain state proceedings. SKS
& Assocs., Inc. v. Dart, 

, 677 (7th Cir. 2010) (citing
Younger v. Harris, 

, 53–54 (1971)). Situations in
which Younger abstention is appropriate include those in
which there is an ongoing state proceeding that is judicial in
nature, involves important state interests, provides the plain-
tiff an adequate opportunity to raise the federal claims, and
no exceptional circumstances exist. Stroman Realty, Inc. v. Mar-
tinez, 

, 662 (7th Cir. 2007). In addition, the consti-
tutional issues raised must be capable of being raised in the
state proceedings, including in the state appellate process.
Simpson v. Rowan, 

, 138 (7th Cir. 1995).
    If Ewell’s federal case were in its infancy in the federal
courts, the district court might have had good reason to stay
its proceedings while the state criminal case was underway.
Ewell could have contested probable cause in the state courts.
But the timeline of the two cases did not lend itself to Younger
abstention, which is proper only when state court proceed-
ings are initiated “before any proceedings of substance on the
No. 16-1009                                                     7

merits have taken place in the federal court … .” Hicks v. Mi-
randa, 

, 349 (1975). This does not call for a simple
check of the calendar to see which case was filed first. A fed-
eral court should abstain when a state criminal complaint is
filed while the federal litigation is an “embryonic stage” and
no contested matter has been decided. Doran v. Salem Inn, Inc.,

, 929 (1975). In all other cases, “federal courts must
normally fulfill their duty to adjudicate federal questions
properly brought before them.” Hawaii Hous. Auth. v. Midkiff,

, 238 (1984). Once a case has progressed beyond
the embryonic stage, “considerations of economy, equity, and
federalism counsel against Younger abstention … .” 

district court considered the issues, entertained
numerous motions, and finally resolved the federal case four
months before the state’s initiation of criminal proceedings
against Ewell. In those circumstances, nothing called for ab-
stention at the district court level, nor should we take that step
at the appellate level. Instead, we will heed our “virtually un-
flagging obligation … to exercise the jurisdiction given” to us,
Colo. River Water Conservation Dist. v. United States, 

, 817 (1976), and proceed.
                                B
   There is, however, another preliminary obstacle to some of
Ewell’s section 1983 claims now that she has been convicted
and sentenced by a state court—a court whose proceedings
are relevant to this matter and the proper subject of judicial
notice. Opoka v. I.N.S., 

, 394–95 (7th Cir. 1996). At
her sentencing, Ewell received credit for the 12 days she spent
in custody following her initial arrest—the same time for
which she now contends she was unlawfully detained. See
Wisconsin v. Ewell, No. 16-CF-231, Sentencing Tr., Dec. 8, 2016.
8                                                   No. 16-1009

The problem she faces is this: a section 1983 plaintiff may not
receive damages for time spent in custody, if that time was
credited to a valid and lawful sentence. Bridewell v. Eberle, 

, 677 (7th Cir. 2013); Ramos v. City of Chicago, 

, 1020 (7th Cir. 2013).
    After reviewing Ewell’s complaint and the 2016 state crim-
inal proceedings, we conclude that Ewell is not entitled to
seek damages related to her detention and therefore to this
extent has no injury that a favorable decision by a federal
court may redress. Without a redressable injury, Ewell lacks
Article III standing to press this claim. See Lujan v. Defenders
of Wildlife, 

, 560–62 (1992).
    We note in passing that the Supreme Court recently held
in Manuel v. City of Joliet, No. 14-9496, 

(U.S.
Mar. 21, 2017), that the Fourth Amendment continues to gov-
ern at least some claims for unlawful pretrial detention even
after the legal process has begun through a judicial probable-
cause determination or comparable procedure. The rule in
this circuit had been that claims (such as Ewell’s) for unlawful
detention could be brought only under the Due Process
Clause once legal process had begun. See, e.g., Llovet v. City of
Chicago, 

, 763 (7th Cir. 2014). Nothing in Manuel,
however, affects the question now before us, which is
whether Ewell is entitled to damages for time spent in cus-
tody that was fully credited to her state sentence.
    This means that Ewell’s conspiracy allegations are out as
well. She asserts almost in passing at the end of her appellate
brief that the district court misread her allegation that the de-
tectives and DA Toney had engaged in a conspiracy to hold
her without charge or probable cause as a claim under section
1985, when she was relying on section 1983. Insofar as she
No. 16-1009                                                       9

notes that plaintiffs do not need to plead legal theories, she is
correct. In addition, it is true that claims for alleged conspira-
cies between state actors are possible under section 1983,
though as we have observed, they add nothing but needless
complexity. See Fairley v. Andrews, 

, 526 (7th Cir.
2009); see also Geinosky v. City of Chicago, 

, 749 (7th
Cir. 2012). But Ewell fails to develop this argument on appeal,
and we have repeatedly noted that perfunctory and undevel-
oped arguments do not preserve a claim for our appellate re-
view. See, e.g., Puffer v. Allstate Ins. Co., 

, 718 (7th
Cir. 2012); United States v. Berkowitz, 

, 1384 (7th
Cir. 1991). Even if she squeaks past forfeiture, she cannot suc-
ceed. In any case, there must be an underlying constitutional
injury or the conspiracy claim fails. Because Ewell cannot
maintain a claim for her alleged unlawful detention—the only
possible injury for this part of the case—her conspiracy claim
also fails.
                                 C
    Ewell’s claim of unreasonable delay in obtaining a prompt
judicial determination of probable cause under Riverside v.
McLaughlin, 

(1991), meets the same fate. In Bride-
well v. Eberle, we determined that a litigant in very similar cir-
cumstances, who was held for 63 hours after her arrest before
a judicial determination of probable cause, could not demon-
strate that she was injured by the presumptively unreasona-
ble delay of more than 48 

–77. The criti-
cal fact was that the judge ultimately found probable cause
and denied bail. The plaintiff thus would not have been enti-
tled to release any sooner. 

her time in
custody was later credited to a criminal sentence on another
charge, she could not receive damages for the time she spent
10                                                 No. 16-1009

in custody after her arrest. 

So too here. The state
court judge found probable cause and denied bond pending
a further hearing in his November 22, 2013 determination.
Had the judicial determination occurred earlier, the outcome
would have been the same: Ewell would not have been re-
leased at that point.
    Even if Ewell could show at least nominal damages from
the delay, our review of the state habeas corpus proceedings
convinces us that the detectives would not be the correct par-
ties to hold liable for any such damages. The judge indicated
that although Detective Ledger had contacted him to review
and sign the probable cause statement within the 48-hour pre-
sumptive period, the judge turned him away and indicated
that he could not possibly have made the determination any
sooner than he did. This suggests that the delay of longer than
48 hours was not a result of the detectives’ actions. And
Ewell’s amended complaint does not assert that either the
county or the police department had any policy or practice
that caused excessive delays. On these facts, she has not stated
a Riverside claim against the defendants she names.
                              III
   That leaves Ewell’s claim for false arrest. While we are
skeptical that she could show any injury from the arrest, her
case was dismissed at the pleading stage, and so she never
had the opportunity to develop a record on this point. But giv-
ing Ewell the benefit of the doubt and assuming that she may
have suffered damages related to the arrest itself—perhaps
emotional injury or nominal damages independent of the
time already credited to her criminal sentence—we must con-
sider whether her suit against the detectives is nevertheless
barred by qualified immunity.
No. 16-1009                                                     11

    Our review of a district court’s ruling on qualified immun-
ity in response to a Rule 12(b)(6) motion is de novo; we con-
sider the facts, including all reasonable inferences from them,
in the light most favorable to the nonmoving party. Chasensky
v. Walker, 

, 1093 (7th Cir. 2014). But we need not
accept any legal assertions as true when we review a dismis-
sal under Rule 12(b)(6). Lodholtz v. York Risk Servs. Group, Inc.,

, 639 (7th Cir. 2015). We may affirm a district
court’s dismissal on any ground contained in the record.
Brooks v. Ross, 

, 578 (7th Cir. 2009).
    “Qualified immunity shields government officials from
civil damages liability unless the official violated a statutory
or constitutional right that was clearly established at the time
of the challenged conduct.” Reichle v. Howards, 

,
2093 (2012). In other words, qualified immunity “shields from
liability police officers ‘who act in ways they reasonably be-
lieve to be lawful.’” Jewett v. Anders, 

, 822 (7th Cir.
2008) (quoting Anderson v. Creighton, 

, 641 (1987)).
Qualified immunity is an affirmative defense, but the plaintiff
carries the burden of defeating it once it is raised. Rabin v.
Flynn, 

, 632 (7th Cir. 2013). To defeat the qualified
immunity defense, a plaintiff must show: (1) that the defend-
ant violated a constitutional right, and (2) that the right was
clearly established at the time so that it would have been clear
to a reasonable officer that her conduct was unlawful in the
situation. Saucier v. Katz, 

, 201–02 (2001). These
questions can be addressed in either order. Pearson v. Callahan,

, 236 (2009); Locke v. Haessig, 

, 667 (7th
Cir. 2015).
    Probable cause is an absolute defense to claims of wrong-
ful or false arrest under the Fourth Amendment in section
12                                                    No. 16-1009

1983 suits. Williams v. City of Chicago, 

, 756 (7th Cir.
2013). In other words, if an officer has probable cause to arrest
a suspect, the arrest was not false. Probable cause exists at the
time of an arrest if “the facts and circumstances within the of-
ficer’s knowledge … are sufficient to warrant a prudent per-
son, or one of reasonable caution, in believing … that the sus-
pect has committed, is committing, or is about to commit an
offense.” 

v. City of Elgin, 

, 537
(7th Cir. 2009)). Probable cause is gauged from the vantage
point of a reasonable officer facing the same situation. 

said little about the detectives’ alleged
lack of probable cause. She pleaded only that “[n]othing [she]
said or did during the … police questioning could have
caused a reasonable law enforcement official to believe that
[she] had engaged in criminal wrongdoing,” and that they did
not have probable cause when they arrested her. But she also
referred to the probable cause affidavit prepared by Ledger in
her complaint. We may take notice of that complaint. See Wil-
liamson v. Curran, 

, 436 (7th Cir. 2013). Ewell con-
tends that it contained “several material false statements and
material omissions.” But she has not pointed to any specific
errors or misstatements, and in district court she asserted that
her claim was not that the detectives had lied or committed
misconduct. And when we asked at oral argument whether
she was contending that the detectives lied in their affidavit,
Ewell refrained from going that far. Instead, she repeated that
nothing in the affidavit established probable cause. We are
therefore free to rely on this affidavit to show what the detec-
tives at least believed to be true at the time, without needing
to make a finding about the truth of the underlying assertions.
No. 16-1009                                                 13

     This permits us to accept for present purposes that at the
time Ewell was arrested, the detectives knew or believed: that
she claimed she had not seen or talked to Timothy Nance
since Friday, November 1, 2013; that she admitted having had
the keys to the Nance house over the following weekend, in-
cluding having been in the house on the following Sunday,
and having spoken to her sister; that video surveillance
showed Ewell and Nance entering a local store and purchas-
ing shower curtain liners and hooks the Friday night that Tim-
othy went missing; that witnesses indicated that the curtains
were replaced after Timothy went missing; and that the
search at the Nance residence had turned up a “projectile”
from the bathtub plumbing pipes. This all plausibly supports
the detectives’ suspicion that Ewell had helped to hide a body
or conceal a homicide.
     None of this, we assume, proves Ewell’s guilt. But the
question before us is a different one: whether a reasonable of-
ficer would have been justified in believing that he had proba-
ble cause to arrest Ewell. Here, it would not have been plain
to a reasonable officer that arresting and detaining Ewell un-
der those circumstances would have been unlawful under the
Fourth Amendment, and this is all that the qualified immun-
ity inquiry requires. Although qualified immunity is some-
times a factual question better reserved for summary judg-
ment, here the pleadings and items subject to judicial notice
support immunity for the detectives.
    We note for the sake of completeness that we need not
reach the issue of absolute or qualified immunity for
DA Toney because Ewell’s allegations against him all stem
from conduct subsequent to her arrest. She alleges that he
learned of her arrest after it occurred, and that he was aware
14                                                 No. 16-1009

while she was detained that probable cause was lacking. But
even assuming this were so, and that she could establish that
he was at least partially responsible for her continued deten-
tion, the only claim she would have had against him is for un-
lawful detention. And, as we already have concluded, she
cannot maintain that claim because she has been credited for
the time served.
    Finally, the appellees contended that some of Ewell’s
claims would be barred by Heck v. Humphrey, 

(1994), which holds that a prisoner’s claims for damages that
would implicate the validity of her underlying conviction or
sentence are not cognizable under section 1983 until she re-
ceives favorable collateral relief, such as through the issuance
of a writ of habeas corpus. The Heck bar is not jurisdictional,
however, and we therefore are not concerned that it would
affect our power to hear this case. Because we may affirm a
dismissal on any ground contained in the record, 

, we decline to reach the Heck issue.
     We therefore AFFIRM the judgment of the district court.
