BEAM, Circuit Judge.

In this interlocutory appeal, Ulenzen C. King and Stephen Furr (collectively, Appellants), law enforcement officials in Saline County, Arkansas, appeal from the district court's denial of qualified immunity on summary judgment. We affirm the denial of qualified immunity to Officer King, reverse as to Officer Furr, and remand for further proceedings.

I. BACKGROUND

On December 18, 2008, Officer Stephen Furr, a deputy sheriff of Saline County, stopped a vehicle in which Johnny Dale Thompson, Jr., was a passenger. After discovering Johnny had an outstanding warrant, Officer Furr and another officer arrested Johnny and placed him in the patrol car. During this encounter, the officers found an empty Xanax bottle on Johnny. The bottle indicated that the Xanax was prescribed to Johnny and filled with sixty pills two days prior to his arrest. While en route to the Saline County Jail, Johnny slept but Officer Furr easily awakened him when they arrived at the jail. In an affidavit, Officer Furr explained, "Inside the jail [Johnny] appeared to be slurring slightly so I asked him if he had taken some of his meds earlier and he said `yes.' I completed my paperwork and left the jail without further incident."

At the jail, Officer Furr left Johnny in the care of jailer Ulenzen King for booking. Officer King noted that Johnny appeared intoxicated, and Johnny asked for a chair to sit down. Johnny leaned forward in his chair but did not fall to the floor. During the booking process, Officer King had to slap the counter to awaken Johnny. Officer King asked Johnny several medical questions, including if he had ingested any medication and how much. Johnny informed Officer King that he suffered from seizures and had taken Dilantin but would not tell Officer King how many pills he had ingested. Due to Johnny's intoxication level, King wrote, "Too Intox to Sign" on Johnny's booking sheet. At approximately 7:42 P.M., Johnny was placed in a cell. At one point, another detainee observed Johnny's intoxicated condition and informed Officer King that Johnny needed help, but Officer King ignored the warning. At 9:09 P.M., Officer King and another officer entered Johnny's cell and discovered Johnny cool to the touch, not breathing, and non-responsive. Johnny was taken to the hospital and pronounced dead at 9:30 P.M.

An autopsy report revealed that Johnny died from a multiple drug intoxication. Among the cocktail of drugs in Johnny's system, the medical examiner's report indicated that "[h]ydrocodone (a narcotic) was present in [Johnny's] blood at a level which could be considered elevated to toxic in and of itself." Johnny's blood also contained methadone, another narcotic, within a therapeutic range. Additionally, the report revealed that Johnny had alprozolam in his system within a therapeutic range. Although Johnny had informed Officer King that he had taken Dilantin, the toxicology report showed no Dilantin in Johnny's system. Ultimately, the medical examiner classified the death as an accident, hypothesizing that Johnny may have "mistakenly [taken] one of the medications by mistake, thinking it was Dilantin."

Johnny's mother, Elaine Thompson, commenced action against Saline County and several Saline County officers individually, alleging federal constitutional claims under 42 U.S.C. § 1983 and state law claims under the Arkansas Civil Rights Act and Arkansas' wrongful death law. The defendants moved for summary judgment, asserting qualified immunity. The district court concluded that Saline County and each individually named defendant, except for Officers Furr and King, were entitled to qualified immunity. Accordingly, the district court granted summary judgment and dismissed most of Thompson's claims but preserved the federal and state law claims against Officers Furr and King. Officers Furr and King now appeal, arguing that the district court erred in concluding they were not entitled to qualified immunity.

II. DISCUSSION

Pursuant to the collateral order doctrine, we have jurisdiction to review this interlocutory appeal only to the extent Appellants' qualified immunity arguments raise an issue of law. Robbins v. Becker, 715 F.3d 691, 693 (8th Cir.2013). We review de novo the denial of summary judgment on the basis of qualified immunity, viewing the evidence and drawing all reasonable inferences in the light most favorable to the non-moving party. Small v. McCrystal, 708 F.3d 997, 1003 (8th Cir. 2013).

When an official asserts qualified immunity in response to a § 1983 action, we conduct a two-pronged analysis: "(1) [whether] the facts, viewed in the light most favorable to the plaintiff, demonstrate the deprivation of a constitutional or statutory right; and (2) [whether] the right was clearly established at the time of the deprivation." Jones v. McNeese, 675 F.3d 1158, 1161 (8th Cir.2012) (alterations in original). As to prong one of this analysis, Thompson alleged that Appellants violated Johnny's substantive due process rights because they were deliberately indifferent to his serious medical needs.

A plaintiff claiming deliberate indifference must establish objective and subjective components. McRaven v. Sanders, 577 F.3d 974, 980 (8th Cir.2009). "The objective component requires a plaintiff to demonstrate an objectively serious medical need. The subjective component requires a plaintiff to show that the defendant actually knew of, but deliberately disregarded, such need." Id. (quotations and citations omitted). On appeal, Appellants only challenged the district court's conclusions on the subjective component. Thus, we limit our review to that issue, solely addressing whether Officers Furr and King actually knew Johnny presented a serious medical need but deliberately disregarded it.

"In order to demonstrate that a defendant actually knew of, but deliberately disregarded, a serious medical need, the plaintiff must establish a mental state akin to criminal recklessness: disregarding a known risk to the inmate's health." Vaughn v. Gray, 557 F.3d 904, 908 (8th Cir.2009) (internal quotation omitted). This onerous standard requires a showing "more than negligence, more even than gross negligence," Popoalii v. Correctional Medical Services, 512 F.3d 488, 499 (8th Cir.2008), but less than "purposefully causing or knowingly bringing about a substantial risk of serious harm to the inmate," Schaub v. VonWald, 638 F.3d 905, 914-15 (8th Cir.2011).

Circumstantial evidence may be used to establish the subjective mental state, and "a factfinder may determine that a defendant was actually aware of a serious medical need but deliberately disregarded it, from the very fact that the [medical need] was obvious." Vaughn, 557 F.3d at 908-09 (alteration in original) (internal quotation omitted). "But `[i]t is not enough merely to find that a reasonable person would have known [about the risk], or that [the officer] should have known' about the risk." Krout v. Goemmer, 583 F.3d 557, 567 (8th Cir.2009) (alterations in original) (quoting Farmer v. Brennan, 511 U.S. 825, 843 n. 8, 114 S.Ct. 1970, 128 L.Ed.2d 811 (1994)). Even acting unreasonably in response to a known risk is not sufficient to prove deliberate indifference. Id. However, if a response to a known risk is obviously inadequate, this may lead to an inference that the officer "recognized the inappropriateness of his conduct." Id.

A. Officer Furr

After evaluating the evidence in the light most favorable to Thompson, the district court concluded that genuine issues of material fact remained as to whether "Officer Furr was subjectively aware of Johnny's need for medical attention and deliberately disregarded it." To reach this conclusion, the district court emphasized that Officer Furr knew that Johnny had an empty Xanax bottle that was filled with sixty pills two days prior and exhibited obvious signs of intoxication. Moreover, the district court highlighted that Officer Furr had asked Johnny if he had taken some of his medication, and Johnny answered in the affirmative. Based on these facts, the district court reasoned, Officer Furr's awareness of the risk could be inferred, and it remained a question of fact whether Officer Furr's response — doing nothing, according to the district court — represented deliberate indifference. Officer Furr asserts that the subjective component of deliberate indifference is not present in this case. We agree.

The present case does not require us to enter uncharted territory, as Grayson v. Ross, 454 F.3d 802 (8th Cir.2006), has already blazed the trail. In Ross, we confronted a situation where an arresting officer sought qualified immunity after a detainee he arrested died due to methamphetamine intoxication and other contributing conditions. Id. at 808. During the arrest, the detainee acted irrationally, informing the officer that his vehicle was going to explode, and became combative, which required the officer to subdue him with a service weapon. Id. at 806. Nevertheless, "once arrested, [the detainee] sat calmly in the back of the patrol car, followed directions, answered questions posed, and remained quiet and seated on a bench inside the jail." Id. at 809. Although the arresting officer likely knew the detainee was under the influence of methamphetamine, we found the subjective component not satisfied because "[the arresting officer] was unsure whether [the detainee] was hallucinating." Id.

Similar to our holding in Ross, the Fourth Circuit, too, has granted qualified immunity to an arresting officer in circumstances not unlike those Officer Furr faced. See Grayson v. Peed, 195 F.3d 692 (4th Cir.1999). In Peed, an officer arrived at a scene involving a detainee "acting crazy." Id. at 694. After searching the detainee, the officer discovered a canister containing marijuana and a canister containing a substance believed to be PCP. Id. The officer placed the detainee under arrest and transported him to a detention facility. Id. While sitting in a cell at the detention facility, the detainee became unconscious and eventually died. Id. at 694-95. In a subsequent § 1983 action against the arresting officer, the mother of the decedent claimed that the officer's decision to transport the detainee to the detention facility instead of a hospital constituted deliberate indifference. Id. at 695. The Fourth Circuit disagreed, concluding that no objective evidence informed the officer that the detainee had a serious medical need. Id. As the court explained, "at the time of their encounter, [the detainee] exhibited to [the arresting officer] no visible external injuries. He did not have trouble breathing. He was not bleeding, was not vomiting or choking, and was not having a seizure. Furthermore, [the detainee] was conscious, at least somewhat responsive, and able to answer questions." Id.

We see very little difference in the encounter between Officer Furr and Johnny, and the encounters illustrated in Ross and Peed. Here, Johnny presented no external injuries and nothing indicates his breathing was abnormal. Johnny was conscious during the initial encounter, answered Officer Furr's questions, and followed instructions. Although Johnny exhibited signs of intoxication by falling asleep in the patrol car and slightly slurring his words, Officer Furr easily awakened him and "[h]is symptoms hardly distinguish him from the multitude of drug and alcohol abusers the police deal with everyday." Peed, 195 F.3d at 696. Our precedent does not permit the presumption of actual knowledge based upon such minor symptoms of intoxication. See, e.g., Ross, 454 F.3d at 809 (finding no subjective knowledge where officer knew detainee was likely under influence of methamphetamine but was unsure if detainee was hallucinating); cf., e.g., McRaven, 577 F.3d at 981 (denying qualified immunity where "officers knew the cocktail of drugs taken by [detainee], and the drug intoxication evaluation showed a severely intoxicated detainee"). And, as Ross and Peed make clear, an officer does not lose the protections of qualified immunity merely because he does not react to all symptoms that accompany intoxication. Therefore, in light of Johnny's relatively innocuous behavior, we do not make much of the fact that Officer Furr discovered an empty Xanax pill bottle coupled with Johnny's indication that he had taken "a little" of his medication. See Ross, 454 F.3d at 810 (finding no deliberate indifference where detainee's behavior "did not suggest a high degree of intoxication"); Peed, 195 F.3d at 696 (finding no deliberate indifference where detainee "was found in possession of drugs while acting irrationally and slurring his speech").

Accordingly, within the confines of the circumstances Officer Furr encountered, we conclude he did not have subjective knowledge that Johnny required medical attention. It follows from this conclusion that Officer Furr was not deliberately indifferent to Johnny's medical needs and is, therefore, entitled to qualified immunity.1

B. Officer King

The district court determined that Officer King was not entitled to qualified immunity because the evidence revealed Officer King recognized that Johnny was intoxicated on prescription medication but failed to respond to Johnny's medical needs. Officer King asserts that the subjective component of deliberate indifference is not satisfied because Officer King did not know of Johnny's serious medical need. Like Officer Furr, Officer King believes Ross supports a grant of qualified immunity in his case. We disagree.

Although we have concluded that Ross entitles Officer Furr to qualified immunity, Ross does not compel the same conclusion for Officer King. Indeed, in Ross, the booking officer dealt with a detainee who was a "calm, non-combative person sitting on a bench answering questions." 454 F.3d at 810. This description lies in stark contrast to Johnny, who passed out in the booking area, nearly fell out of his seat, was unable to sign his name, and, according to plaintiff's version of the facts, "couldn't even answer questions that Officer King was asking him." In sum, Johnny presented a noticeably more intoxicated condition during his encounter with Officer King than the detainee in Ross. Therefore, distinguishing Ross, we turn to the specific circumstances Officer King confronted.

The district court properly highlighted the relevant facts: Officer King had to slam his hand on the counter to keep Johnny from passing out and was well-aware that Johnny exhibited a heightened intoxicated state, even writing "Too Intox To Sign" on Johnny's booking sheet.2 Further, in the incident report, Officer King admitted that he believed Johnny's intoxication stemmed from prescription seizure medication but could not confirm how much medication Johnny ingested. Not only did Johnny have noticeable symptoms of severe intoxication while Officer King booked him, a fellow detainee, Bobby Harrison, also later warned Officer King that Johnny needed help after Johnny's body slid down the window of his jail cell.3 According to Harrison, anyone witnessing Johnny's condition at the jail would have recognized he needed medical attention. Officer King did nothing in response. When these circumstances are viewed in combination, we think a reasonable jury could find Officer King had subjective knowledge of a serious medical need and deliberately disregarded that need.

Because we have concluded that a jury question exists as to whether Officer King violated Johnny's constitutional rights, we now move to the second prong of the qualified immunity analysis: "[whether] the right was clearly established at the time of the deprivation." Jones, 675 F.3d at 1161 (alteration in original). "In determining whether a right is clearly established, we ask whether it would be clear to a reasonable officer that his conduct was unlawful in the situation he confronted."4 El-Ghazzawy v. Berthiaume, 636 F.3d 452, 459 (8th Cir.2011) (quotation omitted). This question requires us to examine precedent to determine if the law "provided fair warning the officer's conduct was unconstitutional." Id. (internal quotation omitted).

The Supreme Court has declared that it is unconstitutional for prison officials to act deliberately indifferent to an inmate's serious medical needs. Estelle v. Gamble, 429 U.S. 97, 104-05, 97 S.Ct. 285, 50 L.Ed.2d 251 (1976). And, we have recognized that a reasonable officer would know that it is unlawful to delay medical treatment for a detainee exhibiting obvious signs of medical distress. Gordon v. Frank, 454 F.3d 858, 863 (8th Cir.2006). Given this precedent, a reasonable officer would have known that a constitutional violation occurs by deliberately disregarding Johnny's serious medical needs in the circumstances Officer King confronted. Therefore, because the constitutional right was clearly established, the district court properly denied Officer King qualified immunity.

III. CONCLUSION

For the forgoing reasons, we reverse the district court's qualified immunity determination as to Officer Furr, affirm the district court's determination as to Officer King, and remand for further proceedings.
