OPINION
Plaintiff-Appellant Veronica McQueen (“McQueen”), mother of the decedent Jane Doe (“Doe”), 1 appeals the district court’s order granting summary judgment in the underlying § 1988 action to DefendantsAppellees Alicia Judd (“Judd”) Jimmie Hughes (“Hughes”), and the Beecher Community School District (“the School District”). 2 McQueen contends that her daughter’s substantive due process rights were violated when she was fatally shot in school by her classmate John Smith (“Smith”), 3 and that the district court erred in holding that she had failed to show the genuine issues of material fact necessary to maintain a direct state-created-danger claim against Judd, a supervisory liability claim against Hughes, and a municipal liability claim against the School District. McQueen also appeals the magistrate judge’s order denying her motion for default judgment.
Because Doe’s substantive due process rights were not violated, we AFFIRM the district court’s judgment granting the defendants’ motion for summary judgment. We DISMISS for lack of jurisdiction the appeal of the magistrate judge’s order, because the parties did not first seek review in the district court.
I. BACKGROUND
“The facts of this case are undeniably tragic.”
DeShaney v. Winnebago County Dep’t of Soc. Servs.,
McQueen allegеs that during the 1999-2000 school year, in the months leading up to the shooting, Smith was involved in several incidents where he attacked other students, sometimes beating them up and other times stabbing them with a pencil. The School District had a policy of expelling students possessing dangerous weapons on school grounds. The School District’s current superintendent testified that a pencil could qualify as a dangerous weapon under the policy, as could a pen or a *463 book. Hughes never attempted to expel Smith for his attacks.
On the morning of the shooting, Smith brought to school a gun that he had obtained from his home. At about 9:45 A.M., Judd lined up her students in the hallway and led thеm to a computer class. Judd left Smith, Doe, and four other students behind as punishment for not doing their work. During this time, Smith took the gun out of his desk, inserted a magazine of bullets, threatened (but did not shoot) a student who had just entered the room, and finally shot Doe, who was sitting at her desk. At the moment of the shooting, Judd was standing about twenty-seven feet down the hall from the classroom.
McQueen brought suit under 42 U.S.C. § 1983, asserting that her daughter’s substantive due process rights were violated. McQueen alleged claims against Judd under a theory of state-created danger, against Hughes under supervisory liability, and against the School District under municipal liability. McQueen moved for default judgment. The district court referred the motion to the magistrate judge, who denied the motion and a subsequent motion for reconsideration. The defendants moved for summary judgment, which the district court granted. McQueen now appeals both decisions.
II. ANALYSIS
A. Summary Judgment of § 1983 Claims
1. Standard of Review
“We conduct de novo review of decisions granting summary judgment, drawing all reasonable inferences in favor of the non-moving party.”
Johnson v. Karnes,
2. Direct State-Created-Danger Claim Against Judd
McQueen argues that Judd violated Doe’s right not to be deprived of life without due process, as secured by Fourteenth Amendment’s Due Process Clause. “[I]t goes without saying that an individual’s ‘interest in preserving her life is one of constitutional dimension.’ ”
Kallstrom v. City of Columbus,
The state-created-danger doctrine has its roots in
DeShaney v. Winnebago County Dep’t of Soc. Servs.,
Every regional court of appeals, including this one, has walked through the door left open by the Court and recognized the state-created-danger theory of constitutional liability under § 1983.
Butera v. District of Columbia,
a. Affirmative Acts that Create or Increase the Risk
“Liability under the state-created-danger theory is predicated upon affirmative acts by the state which either create or increase the risk that an individual will be exposed to private acts of violence.” Id. at 1066. In Kallstrom, we held that this first requirement was satisfied where a city “releas[ed] private information from [undercover] officers’ personnel files” to defense counsel representing violent gang members whom the officers had investigated. Id. at 1067. Although we have sometimes assumed the affirmative-act-plus-risk-creation requirement to be satisfied, 5 *465 Kallstrom remains the only time we have explicitly held it to be met.
In contrast, on numerous occasions we have rejected claims because the challenged conduct either was not an affirmative act at all or did not create or increase the risk of private violence to the plaintiff.
Schroder v. City of Fort Thomas,
McQueen argues that when Judd left Smith and several classmates, unsupervised, in the classroom while taking the rest of her students to -another room down the hall, she cоmmitted a Kallstrom affirmative act that created a risk that Doe would be harmed by Smith. The district court rejected this argument, finding that it was mere “hindsight deduction” to posit that Smith would not have been able to fire the gun if Judd had been in the room. J.A. at 56 (Dist. Ct. Op. and Order at 10).
We have not previously considered whether it constitutes an affirmative-act-plus-risk-creation under Kallstrom for a teacher to leave students — and more pertinently, the student who ultimately causes the injury — unsupervised. 6 The decisions reviewed above, however, provide enough guidance to conclude that Judd’s leaving Smith and several of his classmates unsu *466 pervised in the classroom was not an affirmative aсt that created or increased the risk for purposes of Kallstrom. The cases most applicable to the situation here are those in which the state officials performed some act, 7 but we held that there was no affirmative act that created or increased the risk because the victim would have been in about the same or even greater danger even if the state officials had done nothing.
First, in
Cartwright,
the police picked up the plaintiff while he was walking at night on the side of the highway and dropped him off at a convenience store parking lot.
Judd’s conduct is analogous to that of the officers in Cartwright and Bukowski and falls far short of the city’s actions in Kallstrom. The danger to Doe was created by Smith’s possession of a gun and Doe’s presence in the classroom with him. This danger existed irrespective of Judd’s location. If Judd had been in the room, there is no guarantee that, upon seeing the gun, she would have gotten to Smith in time to prevent the shooting; indeed, in a busy classroom, she may not have even noticed Smith’s actions until the fatal moment. (Perhaps if Judd had been standing right next to Smith, she could have wrested the gun from him before he loaded and fired it. But there is no guarantee that Judd would have been so positioned if she had been in the room.) Also, there is no reason to believe that Judd’s presence in the room would have discouraged Smith from drawing the weapon, as Smith’s behavioral issues indicate that he did not shy away from misbehaving directly in Judd’s view. Therefore, just as the plaintiffs in Cartwright and Bukowski would have faced at least the same danger if the police had not acted, Doe would have faced the danger of Smith drawing his gun and firing at her even if Judd had not acted (i.e., if Judd had remained in the classroom at all relevant times).
McQueen relies principally on two decisions from other circuits to support her
*467
contention that Judd committed an affirmative act that created or increаsed the risk for state-created-danger purposes. McQueen first invokes
L.W. v. Grubbs,
Defendants knowingly assigned [the inmate] to work with [the nurse] despite their knowledge that: (1) [the inmate] was not qualified to serve as a cart boy; (2) [the inmate] had an extraordinary history of unrepentant violence against women and girls; (3) [the inmate] was likely to assault a female if left alone with her; (4) [the nurse] would be alone with [the inmate] during her rounds; and (5) [the nurse] would not be prepared to defend against or take steps to avert an attack because she had not been informed at hiring that she would be left alone with violent offenders.... The defendants also enhanced [the nurse’s] vulnerability to attack by misrepresenting to her the risks attending her work.
Id. at 121. The Grubbs defendants took the outright step of assigning an inmate with known violent tendencies toward women to work alone with the female plaintiff. Judd’s walking out of the classroom cannot be characterized as such an overt act of danger-creation.
McQueen also cites
Dorothy J. v. Little Rock Sch. Dist.,
In sum, McQueen has not shown sufficient evidence to raise a genuine issue of material fact as to an affirmative act that created or increased the risk of private violence to Doe.
b. Special Danger
In addition to an affirmative act, “plaintiffs alleging a constitutional tort under § 1983 [must] show [a] ‘special danger.’ ”
*468
Kallstrom,
As with the affirmative act requirement, we have set a high bar for the special danger requirement. In
Kallstrom,
we held that the second requirement was satisfied where the City’s release of private information from undercover officers’ personnel files “placed the personal safety of the officers and their family members, as distinguished from the public at large, in serious jeopardy.”
We believe that when five children are left in a room alone with an armed classmate, as was the case here, the сhildren are much more like the few officers and family members at risk in Kallstrom than the general public at risk in Schroder, City of Carlisle, and Janan. Smith was much more likely to shoot the students in his immediate physical presence than a member of the general public. There are, of course, arguments to the contrary: (i) Smith could have walked out of the room and fired at those in the hallway or in other rooms; and (ii) he posed a risk to the general public both because he could have left the school with the gun and because even shots fired inside a school can pass through walls or windows to harm victims outside. The first counterargument is of no avail, because we have little difficulty assuming that if the relevant group included everyone in the school, the special danger requirement still would be satisfied. The latter argument misses the mark for a different reason. While we do not discount the risks Smith posed to those outside his school (i.e., the general public), those risks were smaller than and collateral to the risks faced by the five children present in the classroom with him. Surely an attack by the gang members in Kallstrom would have created analogous collateral risks to the general public, yet it was no bar to our holding that the officers and their families, who as the likely targets of such attacks were more likely to be harmed, faced a special *469 danger. Therefore, MсQueen has shown sufficient evidence to raise a genuine issue of material fact as to the existence of a special danger.
c. State Culpability
In
Kallstrom,
we characterized the third element of the state-created-danger theory as a requirement that “[t]he state must have known or clearly should have known that its actions specifically endangered an individual.”
We have equated deliberate indifference with subjective recklessness,
Ewolski,
McQueen argues that, based on Smith’s history of behavioral problems, Judd knew that Smith might violently assault another student and acted recklessly in conscious disregard of that risk by leaving leaving Smith and several other children unsupervised in the classroom. The district court rejected this contention.
McQueen has failed to produce any evidence showing that Judd acted with deliberate indifference. It is difficult to put it better than Judge Friedman ably did in his decision below:
[Although Judd was aware of [Smith’s] disruptive and sometimes violent behavior, no reasonable fact finder could conclude thаt she knew [Smith] would use a gun to kill another student if left unsupervised for a few minutes. Plaintiff does not claim that [Smith] ever specifically threatened to kill or seriously injure decedent [Doe] or any other student. Nor does plaintiff claim that prior to February 29, 2000, [Smith] had ever brought a gun or other dangerous weap *470 on to school. Absent such evidence, it is impossible to conclude that defendant was on notice of a substantial risk to the students left alone in the classroom.
J.A. at 57 (Dist. Ct. Op. and Order at 11). McQueen has not alleged that Judd knew or even suspected that Smith had a gun, knife, or other similarly dangerous weapon with him on the day of the shooting, nor did Smith’s history of behavioral problems suggest that he would escalate from hitting with fists, feet, and pencils to such weapons. Absent such evidence, McQueen cannot show that “the risk [of such a violent attack by Smith] was so obvious that [Judd] had to have known about it.”
Bukowski,
3. Supervisory Liability Claim Against Hughes
McQueen argues that Hughes is liable under § 1983 on a supervisory liability theory for her failures to expel Smith, to train teachers to deal with violent students, to adopt policies protecting students from violent assaults, and to prevent teachers from leaving children unattended in classrooms. The district court held that Hughes is protected by qualified immunity-
Respondeat superior is not a proper basis for liability under § 1983.
Leary v. Daeschner,
These principles make clear that a prerequisite of supervisory liability under § 1983 is unconstitutional conduct by a subordinate of the supervisor. For example, when we have addressed supervisory liability claims against principals and other school officials, it has been in the context of clear unconstitutional conduct by teachers.
See, e.g., Doe v. City of Roseville,
*471 4. Municipal Liability Claim Against the School District
Finally, McQueen argues that the School District is liable under a theory of municipal liability, alleging that it failed to supervise students, failed to expel Smith, and failed to train teachers to properly handle violent students. The district court rejected this claim.
In
Monell v. Dep’t of Soc. Servs.,
As with supervisory liability, “[w]here ... a municipality’s liability is alleged on the basis of the unconstitutional actions of its employees, it is nеcessary to show that the employees inflicted a constitutional harm.”
Ewolski,
5. Summary
Because McQueen has failed to show sufficiеnt evidence to raise a genuine issue of material fact with respect to two of the three requirements under the state-created-danger theory, she has no viable direct claim against Judd. Without an underlying constitutional violation, McQueen cannot maintain her supervisory and municipal liability claims against Hughes and the School District, respectively. Therefore, the district court properly granted the defendants’ motion for summary judgment on all three claims.
B. Magistrate Judge’s Denial of Motion for Default Judgment
Finally, McQueen argues that the magistrate judge erred in denying her motion for default judgment. If a magistrate judge is given plenary jurisdiction pursuant to 28 U.S.C. § 636(c)(1),
10
then “appeal to this court is ‘in the same manner as an appeal from any other judgment of the district court.’ ”
McGraw v. Connelly (In
*472
re Bell & Beckwith),
Here, the district court referred McQueen’s motion for default judgment to the magistrate judge for hearing and determination pursuant to 28 U.S.C. § 636(b)(1)(A). 11 In other words, the magistrate judge was not given plenary jurisdiction under § 636(c)(1). Because the parties did not seek review of the magistrate judge’s order in the district court, we lack jurisdiction to review the magistrate judge’s order denying McQueen’s motion for default judgment.
III. CONCLUSION
Jane Doe’s senseless death was an undeniable tragedy, and we offer our most heartfelt condolences to those who knew and loved Jane. “Judges and lawyers, like other humans, are moved by natural sympathy in a case like this to find a way for [Jane] and [her] mother to receive adequate compensation for the grievous harm inflicted upon them.”
DeShaney,
Notes
.We use the pseudonym Jane Doe to protect the identity of McQueen’s minor child.
Hodge v. Hurley,
. Before the district court, McQueen did not contest the motion for summary judgment as to Defendants Ira Rutherford, Casandra Ingersoll, and Cassandra Coney-Stewart. Although McQueen initially pursued an appeal as to Defendant Elaine Childerhоse, she has now abandoned that claim.
. We use the pseudonym John Smith to protect the identity of a minor child.
Hodge,
. The parties agree that this exception does not apply in this case, presumably in recognition of our prior holdings that there is no "special relationship” between a school and its students that gives rise to a constitutional duty.
Soper v. Hoben,
. In
Ewolski v. City of Brunswick,
. Indeed, it appears that we have only once addressed the state-created-danger theory on facts fitting the general pattern of this case (i.e., a statе official allegedly creating the danger by leaving the violent private actor unsupervised). In an unpublished opinion, we simply assumed the existence of an affirmative act that created the risk but rejected the claim under the third
Kallstrom
prong.
See Duvall v. Ford,
No. 98-5777,
. The cases in which the state officials did nothing, see Union County; Weeks; Sheets; Sargi; Gazette, are inapplicable here because McQueen complains that Judd did something, i.e., leave the classroom.
. In
Union County,
where the police failed to serve in a timely manner an ex parte order obtained by the plaintiff against her ex-husband, we held that the police did not commit an affirmative act, nor did it “place her
specifically
at risk.”
. Because Hughes did not violate Doe’s constitutional rights, "there is no necessity for further inquiries concerning qualified immunity.” Saucier
v. Katz,
. Section 636(c)(1) provides in relevant part, "Upon the consent of the parties, a ... magistrate judge ... may conduct any or all proceedings in a ... civil matter and order the entry of judgment in the case, when specially designated to exercise such jurisdiction by the district court ....”
. Section 636(b)(1)(A) provides in relevant part, "a judge may designate a magistrate judge ... to hear and determine any pretrial matter pending before the court, except [for certain enumerated motions]. A judge of the court may reconsider any pretrial matter under this subparagraph (A) where it has been shown that the magistrate judge’s ... order is clearly erroneous or contrary to law.”
