RILEY, Circuit Judge

        Margaret Hayek (Hayek), the mother of and trustee for William Charles Hayek
(William), filed an action alleging a claim under 42 U.S.C. § 1983 and also alleging
state law claims based on negligence and battery against the City of St. Paul (City)
and the St. Paul police officers (officers) involved in the shooting death of William,
as well as a claim against the City for a violation of the Minnesota Constitution, art.
I, §§ 7 & 8. Claiming qualified and official immunity, and failure to state a claim, the
City and the officers filed a motion for summary judgment. The district court,1
finding no federal or state constitutional violation and finding the officers’ conduct
was not willful or malicious, granted the City’s and officers’ motion for summary
judgment. We affirm.

I.     BACKGROUND
       Hayek lived with her son, William, in an apartment in St. Paul, Minnesota.
William graduated from high school in June 2002. William was 19 years old and was
approximately six-feet seven-inches tall and weighed about 300 pounds. William
owned a replica Samurai sword made of very heavy metal with a blade approximately
three-and-one-half feet in length.

       During the summer of 2002, William applied for, but did not get, a job as an
airport security guard. William became depressed as a result of his failure to obtain
employment and to get a driver’s license. Hayek noticed a change in William’s
temperament and moods.

       Hayek spent most of September 2, 2002, at the Minnesota State Fair. Before
Hayek left her apartment that day, William told her he did not feel well, thought he
had the West Nile virus, and did not want to die. Although concerned, Hayek did not
think she needed to seek help for William at that time. Thus, Hayek left her apartment
and went to the fair.

       Upon returning to her apartment at approximately 10:00 p.m., Hayek found
William sitting in a chair holding a Bible in one hand with his Samurai sword beside
him. Hayek noticed a box on the floor containing toys and video games, and when
she attempted to pick up the box, William told Hayek, “Don’t touch them.” William

of Minnesota.

                                         -2-
said, “Go to your sister’s,” but Hayek responded she would not go to her sister’s
home. William then got up, locked the apartment door, and sat down again. Hayek
noticed William staring at the television, but the television picture was all snow. At
that point, Hayek asked William, “What’s going on?” William replied, “You don’t
know what’s going on. You’ll find out.” William then told Hayek, “I love you Mom,
but you have the devil in you.” William’s behavior frightened Hayek, and she went
into her bedroom.

       Once in her room, Hayek called First Call for Help and then Crisis Intervention
to report her son’s behavior, and was advised to call the police. Hayek also received
a telephone call from her friend who had spoken with William earlier that day.
Hayek’s friend informed her William believed “the police were out to get him, the
police tapped his phone,” and “the police thought he was a bad guy.” At her friend’s
request, Hayek immediately called Patricia Motter (Motter), Hayek’s sister, a
counselor for mentally disabled persons. Motter attempted to talk to William on the
telephone, but William refused and disconnected the call. Hayek then called her
cousin, Budde Lee (Budd). Budd advised Hayek he had spent the day with William,
and William was “going in and out of reality.”

       Meanwhile, Motter called 911 because she was concerned about Hayek. The
911 operator dispatched St. Paul police officers to Hayek’s residence. The 911
operator also called Hayek. Hayek told the operator William claimed Hayek had the
devil inside her and William had to get it out. The 911 operator told Hayek to get out
of the house or go to a different room. After talking to the 911 operator, Hayek
grabbed the keys to the apartment, told William she had to get something out of her
truck, and went outside, where she met St. Paul Police Department Officers Neil
Nelson (Officer Nelson) and Matthew Toronto (Officer Toronto). Hayek advised the
officers she thought William was having a nervous breakdown, he was not on any
medications or drugs, and she did not want William hurt. Hayek gave the officers the
keys to her apartment.

                                         -3-
       Officers Toronto and Nelson entered the apartment and found William sitting
in a chair holding his Samurai sword in his lap. Officer Nelson asked William to put
down his sword. William replied he could not because he was doing his job. William
told the officers his mom was the devil, she had been mean to him lately, and that “it
was his job to get the devil out of his mom.” William also stated the cops had been
after him. The officers told William they “were there to help him” and “were his
friends,” and again asked William to put down his sword. Officer Nelson asked
William what he was watching on televison. William replied he was not watching
televison, he was just reading the Bible. Again, the officers asked William to put
down his sword. William refused and told the officers, “You’re the devil. My mom’s
the devil. Budd’s the devil. He is trying to poison me.” When Officer Toronto asked
William how Budd was trying to poison William, William threw a bottle of pills to the
floor. By this time, other St. Paul police officers had arrived on the scene, including
Officers Peter Crum (Officer Crum), John Linssen (Officer Linssen), and Jay
Thompson (Officer Thompson) and his canine partner, Harley.

       Officer Toronto continued to try to convince William to put down his sword.
Eventually, William shrugged his shoulders, said “okay,” laid down his sword, and
voluntarily walked out of the apartment into the hallway. Officer Toronto told
William everything would be okay and they were going to get William some help.
Officer Toronto directed William to turn around and put his hands on his head. Officer
Toronto placed a handcuff on William’s right hand. However, when Officer Toronto
tried to handcuff William’s left hand, William resisted, pushed the officer, pulled
away, and ran toward the apartment. Officer Toronto attempted to stop William;
Officer Thompson then yelled “Canine stop!” and released Harley. The police canine
chased William into the apartment and bit his leg. Officer Thompson also followed
William inside the apartment to stop William from acquiring the Samurai sword and
hurting himself or anyone else.




                                         -4-
       Inside the apartment, Officer Thompson attempted to stop William from
grabbing his sword. William, however, managed to grab his sword and started to
swing the sword first at Harley and then at Officer Thompson. William slashed
Officer Thompson’s arm. Officer Thompson recalled Harley, then yelled for help and
began to retreat by crawling away on his hands and knees. Believing William was
going to kill Officer Thompson, Officers Crum and Linssen fired their weapons and
shot William. However, the officers’ shots did not stop William from attacking
Officer Thompson. After being shot, William responded “ow,” but continued to stab
Officer Thompson. In an attempt to escape, Officer Thompson continued to crawl on
his hands and knees, but William followed him and stabbed Officer Thompson in his
right arm. The sword went through Officer Thompson’s arm into his chest, breaking
a rib and puncturing Officer Thompson’s right lung. Officer Thompson continued to
crawl, but William pursued and stabbed Officer Thompson through his right leg. At
that time, Officer Nelson fired his shotgun at William, killing William. Officer
Thompson survived the incident. Officer Thompson was hospitalized for two-and-
one-half weeks, and returned to work two-and-one-half months later.

       Hayek filed a lawsuit alleging claims under 42 U.S.C. § 1983 and state law
claims based on negligence and battery and on the Minnesota Constitution, art. I, §§ 7
& 8. The City and the officers filed a motion for summary judgment, claiming
qualified immunity and no federal constitutional violation on the § 1983 claim, and
official immunity and no state constitutional violation on the state law claims. The
district court granted the City’s and the officers’ motion. This appeal followed.

II.    DISCUSSION
       Hayek contends federal and state constitutional violations occurred, and the
City and officers are not entitled to either qualified or official immunity; thus, the
district court erred in granting summary judgment. We review de novo a grant of
summary judgment. Pope v. ESA Servs., Inc., 

, 1006 (8th Cir. 2005).
Summary judgment is proper if, after viewing the evidence and drawing all reasonable

                                         -5-
inferences in the light most favorable to the nonmovant, no genuine issues of material
fact exist and the movant is entitled to judgment as a matter of law. Fed. R. Civ. P.
56(c); 

.

       A.     Section 1983 Claim
       Section 1983 provides a cause of action against government officials who
deprive persons of “rights, privileges, or immunities secured by the Constitution.” 42
U.S.C. § 1983. However, government officials are entitled to a dismissal “if their
conduct does not violate clearly established statutory or constitutional rights of which
a reasonable person would have known.” Sanders v. City of Minneapolis, Minn., 

, 526 (8th Cir. 2007) (quotation omitted). “In addressing an officer’s claimed
entitlement to qualified immunity, the court must first determine whether the
allegations amount to a constitutional violation, and then, whether that right was
clearly established.” 

v. Katz, 

, 201 (2001)).
“Qualified immunity is not just a defense to liability, it constitutes immunity from
suit.” Hanig v. Lee, 

, 824 (8th Cir. 2005). If the allegations and
undisputed facts do not amount to a constitutional violation, there is no necessity for
further inquiries concerning qualified immunity. Ambrose v. Young, 

,
1077 n.3 (8th Cir. 2007) (standard of review explained).

       Because Hayek’s case presents an issue of whether the officers used excessive
force, we must analyze the case under the Fourth Amendment’s objective
reasonableness standard. See Craighead v. Lee, 

, 961 (8th Cir.) (internal
quotation marks and citations omitted), cert. denied, 

(2005). “‘[T]he
question is whether the officers’ actions are “objectively reasonable” in light of the
facts and circumstances confronting them, without regard to their underlying intent
or motivation.’” 

v. Connor, 

, 388 (1980)).
“Apprehension by the use of deadly force is a seizure subject to the reasonableness
requirement of the Fourth Amendment.” 

the suspect poses no
immediate threat to the officer and no threat to others, the harm resulting from failing
to apprehend him does not justify the use of deadly force to do so.’” 

Tennessee v. Garner, 

, 11 (1985)). However, “[w]here the officer has
probable cause to believe that the suspect poses a threat of serious physical harm
either to the officer or to others, it is not constitutionally unreasonable to prevent
escape by using deadly force.” Brosseau v. Haugen, 

, 197-98 (2004)
(quoting 

).

       Here, the facts viewed in the light most favorable to Hayek, show the officers’
use of deadly force was urgent and necessary to protect an officer under attack and
was not constitutionally unreasonable. William posed a significant risk of death or
serious physical injury to the officers. William stabbed Officer Thompson more than
once with the Samurai sword, inflicting serious injuries. The officers’ response was
a reasonable defensive action and did not violate William’s Fourth Amendment right
to be free from unreasonable seizures.

       Hayek argues deadly force was not reasonable because the officers’ actions
escalated the situation. Specifically, Hayek asserts the officers provoked William’s
paranoia by (1) attempting to handcuff him; (2) releasing Harley, the canine partner;
and (3) reentering the apartment after William fled inside. These arguments lack
merit. The officers reasonably feared William would use the sword to hurt himself
or others. The officers could not leave the scene and abandon Hayek with William.
The facts show a 911 call was placed because William, while holding a three-and-a-
half foot long Samurai sword, told Hayek she had the devil inside her. Hayek
confirmed this statement and was afraid William would try to get the devil out of her
with the sword. The officers had probable cause to believe William posed a threat of
serious physical harm to himself, Hayek, and others. The officers did not escalate the
situation; rather, they merely reacted to William’s threatening and violent behavior,
resulting in the officers’ use of deadly force to save Officer Thompson from William’s
violent attack.

    Here, the undisputed facts show William had repeatedly stabbed Officer
Thompson with a Samurai sword, as the officer crawled on his hands and knees
                                    -7-
attempting to escape. The officers used deadly force after William stabbed Officer
Thompson, but this first use of deadly force was ineffective in stopping or controlling
Williams, who continued to pursue Officer Thompson with the Samurai sword. The
officers used deadly force again, resulting in William’s death. The officers’ decision
to use deadly force to protect a fellow officer under attack was reasonable and
justified.

        Hayek claims William’s mental disability (which is not documented in the
record) should have precluded the use of deadly force. Even if William were mentally
ill, and the officers knew it, William’s mental state does not change the fact he posed
a deadly threat to the officers. See 

. (“Knowledge of a
person’s disability simply cannot foreclose officers from protecting themselves, the
disabled person, and the general public when faced with threatening conduct by the
disabled individual.” (citing Bates ex rel. Johns v. Chesterfield County, Va., 

, 372 (4th Cir. 2000))). See also Hassan v. City of Minneapolis, __ F.3d __, __
(No. 06-3504), 

(8th Cir. May 31, 2007).

       The officers had every reason to believe William would have killed Officer
Thompson or any of them; thus, it was reasonable for the officers to use deadly force,
and no federal constitutional violation occurred. “Without a constitutional violation
by the individual officers, there can be no § 1983 or Monell2 . . . municipal liability.”

. (citing City of Los Angeles v. Heller, 

, 799
(1986) (per curiam)); see 

n.3. The district court properly
granted summary judgment in favor of the City and the officers with respect to
Hayek’s § 1983 claim.

       Monell v. New York City Dep’t of Soc. Servs., 

, 694 (1978).

      B.     State Law Claims
             1. Official Immunity
       “The official immunity doctrine provides that a public official charged by law
with duties which call for the exercise of his judgment or discretion is not personally
liable to an individual for damages unless he is guilty of a willful or malicious
wrong.” Elwood v. County of Rice, 

, 677 (Minn. 1988) (internal
quotation marks omitted). Under Minnesota law, the decision to use deadly force is
a discretionary decision entitling a police officer to official immunity absent a willful
or malicious wrong. Maras v. City of Brainerd, 

, 77 (Minn. Ct. App.
1993). “In determining whether an official has committed a malicious wrong, we
consider whether the official has intentionally committed an act that he or she had
reason to believe is prohibited.” State by Beaulieu v. City of Mounds View, 

, 571-72 (Minn. 1994). This “contemplates less of a subjective inquiry
into malice, which was traditionally favored at common law, and more of an objective
inquiry into the legal reasonableness of an official’s actions.” 

Official
immunity also protects government entities from vicarious liability for actions that are
entitled to immunity. Wiederholt v. City of Minneapolis, 

, 316
(Minn. 1998). See also Hassan, 

at *4.

       Because the officers’ use of deadly force was reasonable, a reasonable fact-
finder could not conclude the officers’ conduct was willful or malicious. Here, the
officers had every reason to believe they were in grave danger, and that using deadly
force against William to protect Officer Thompson and themselves was reasonable.
No facts, or reasonable inferences, in the record show the officers’ conduct was willful
or malicious. Thus, under Minnesota law, the officers are entitled to official immunity
as to all state law claims based on negligence and battery. 

     Hayek argues William’s mental state prevents officers from claiming official
immunity. However, as explained above, even if William were mentally ill, William’s
mental state does not change the fact he posed a deadly threat to the officers. Cf.

(holding the city of Minneapolis and its officers did not
                                        -9-
violate the Fourth Amendment and were entitled to summary judgment when the
officers used deadly force against a mentally ill person who posed a deadly threat).
Here, the officers used deadly force after William attacked Officer Thompson with a
Samurai sword, stabbing Officer Thompson in the arm and leg, piercing his chest.

       Hayek also contends the officers are not entitled to official immunity because
they failed to follow their ministerial duties under the police department’s Policy on
Emotionally Disturbed Persons (policy). See Mumm v. Mornson, 

,
493 (Minn. 2006) (holding that the officers were not entitled to official immunity
because they failed to comply with ministerial policy). This policy states, among
other things, officers should restrain emotionally disturbed persons, reduce fear in the
disturbed person by trying to establish a friendly relationship, and prevent injuries to
the officers, the disturbed person, and any bystanders. Assuming the officers knew
or reasonably suspected William was mentally ill, the record clearly shows the officers
adequately complied with this policy.3 The officers attempted to establish a friendly
relationship with William, to restrain William, and to protect William, themselves, and
Hayek by ordering and pleading with William to put down his sword. The officers
used deadly force after William stabbed Officer Thompson and continued to pursue
the officer. After William stabbed Officer Thompson, the officers’ conduct, under
such exigent circumstances, was manifestly discretionary. See Bailey v. City of St.
Paul, 

, 701 (Minn. Ct. App. 2004) (“Public officials responding to
emergencies often face circumstances that, by their nature, require the exercise of
discretion.”). Thus, the officers here are entitled to official immunity. Because the
officers’ discretionary actions are entitled to official immunity, the City has no
vicarious liability. See 

; Dokman v. County of
Hennepin, 

, 297 (Minn. Ct. App. 2001) (“Vicarious official immunity
protects a governmental entity from liability based on the acts of an employee who is
entitled to official immunity.”). Summary judgment was properly granted.


      3
        Because we conclude the officers complied with the policy, we do not reach
the issue of whether the policy at issue here is, as Hayek argues, ministerial in nature.
                                          -10-
              2. State Constitution Claim
       Hayek also claims the officers violated William’s rights under the Minnesota
Constitution. Citing sections 7 and 8 of art. I (Bill of Rights) of the Minnesota
Constitution,4 Hayek contends she is entitled to compensation for William’s death
under a theory of denial of life without due process and inverse condemnation.
However, as the district court noted, Hayek provides no authority to support this
claim. We know of no such Minnesota authority, and conclude Hayek’s contention
has no merit under the facts of this case. Thus, the district court properly dismissed
this state constitutional claim.

III.   CONCLUSION
       We affirm the well reasoned opinion and the judgment of the district court.
