Foreseeability—Not “Special Relationship”—Controls Suicide Proximate Cause Under Tennessee Law, and Spoliation Suspicion Alone Cannot Defeat Summary Judgment

I. Introduction

In Tiffany Barringer v. Sara Jones, the Sixth Circuit (applying Tennessee law in a diversity wrongful-death suit) affirmed summary judgment for a stepmother accused of negligently failing to secure a rifle and ammunition that her stepson used to die by suicide. The plaintiff, the decedent’s mother and estate administrator, argued that the suicide was foreseeable because the stepmother knew of a prior suicide attempt, participated in a safety routine around insulin, observed depressive sleep patterns, and later deleted text messages with the decedent.

The central issue was proximate cause: whether, at the time of the alleged negligence (the night before the death), the suicide was a reasonably foreseeable probability rather than a remote possibility under Tennessee law. A related issue was whether Tennessee’s historically recognized “special-relationship” suicide doctrine could apply outside medical-type relationships (e.g., step-parent/child or homeowner/household member).

II. Summary of the Opinion

The court held that the plaintiff failed, as a matter of law, to produce affirmative evidence from which a rational jury could find the suicide reasonably foreseeable at the relevant time. The court emphasized that knowledge of a prior attempt, ongoing therapy, and generalized suicide risk did not establish the acute, contemporaneous suicidal frame of mind that Tennessee’s leading case Cotten v. Wilson requires for foreseeability in this context.

The court also rejected reliance on the stepmother’s deletion of text messages as a basis to survive summary judgment: while deletion could undermine credibility, it did not supply affirmative evidence of what the messages contained or of notice-level suicidal ideation. Finally, the court declined to expand the “special-relationship” pathway beyond medical-type relationships for suicide proximate-cause analysis, and affirmed judgment for the defendant.

III. Analysis

A. Precedents Cited

• Greer v. Strange Honey Farm, LLC, 114 F.4th 605 (6th Cir. 2024) and Biegas v. Quickway Carriers, Inc., 573 F.3d 365 (6th Cir. 2009)
  These cases provide the Erie framework the panel used: state law governs substantive issues (here, Tennessee negligence and proximate cause), while federal law governs procedure (here, Rule 56 summary judgment).
• Barr v. Lafon, 538 F.3d 554 (6th Cir. 2008), Anderson v. Liberty Lobby, Inc., 477 U.S. 242 (1986), Street v. J.C. Bradford & Co., 886 F.2d 1472 (6th Cir. 1989), Celotex Corp. v. Catrett, 477 U.S. 317 (1986), Goodwin v. City of Painesville, 781 F.3d 314 (6th Cir. 2015)
  These authorities shaped the court’s evidentiary lens. Most importantly, Anderson and Street grounded the key holding on the deletion-of-texts point: even if a jury could disbelieve the defendant, the nonmovant must still provide affirmative evidence to create a genuine issue on an element (foreseeability/proximate cause) on which she bears the burden. Goodwin was used to explain when credibility can be genuinely disputed, but the panel distinguished “credibility impeachment” from “affirmative proof” of foreseeability.
• Giggers v. Memphis Hous. Auth., 277 S.W.3d 359 (Tenn. 2009)
  This supplied Tennessee’s negligence elements, allowing the panel to focus the appeal on proximate cause.
• McClenahan v. Cooley, 806 S.W.2d 767 (Tenn. 1991), King v. Anderson County, 419 S.W.3d 232 (Tenn. 2013), Hale v. Ostrow, 166 S.W.3d 713 (Tenn. 2005)
  These cases provided the Tennessee proximate-cause/foreseeability standard: the injury must be a reasonably foreseeable probability; the defendant need not foresee the exact manner of injury, but must foresee the general type of harm that would be expected from the negligence.
• Cotten v. Wilson, 576 S.W.3d 626 (Tenn. 2019)
  This was the controlling substantive precedent. The panel treated Cotten as the “leading Tennessee decision involving suicide” and used it as the template for analyzing what evidence is sufficient (or insufficient) to show suicide as reasonably foreseeable. The opinion imported Cotten’s insistence on “solid evidence” that suicide was a foreseeable probability—especially because intentional acts are less anticipatable than negligence.
• Borne v. Celadon Trucking Servs., Inc., 532 S.W.3d 274 (Tenn. 2017), Cotten v. Wilson, 576 S.W.3d 626 (Tenn. 2019), Davis v. McGuigan, 325 S.W.3d 149 (Tenn. 2010)
  These framed superseding cause. Critically, the panel explained that in suicide cases the usual affirmative-defense allocation functionally collapses: because the “injury” and the “intervening act” are the same (the suicide), the dispositive question becomes whether the plaintiff can prove foreseeability as part of proximate cause, consistent with Cotten.
• Watters v. TSR, Inc., 904 F.2d 378 (6th Cir. 1990)
  Quoted through Cotten to reflect Tennessee’s historical reluctance to treat suicide as a proximate consequence of wrongful acts.
• Delaney v. Reynolds, 825 N.E.2d 554 (Mass. Ct. App. 2005)
  Used (again through Cotten) as a contrasting illustration of “acute suicidality”: repeated recent expressions of desire to die, including an instance where the defendant handed over a gun. The Sixth Circuit invoked this contrast to show what the record in Barringer lacked.
• Downs ex rel. Downs v. Bush, 263 S.W.3d 812 (Tenn. 2008) and Biscan v. Brown, 160 S.W.3d 462 (Tenn. 2005)
  Cited by the plaintiff to argue for a broader conception of “special relationship,” drawn from duty-to-act doctrine. The panel distinguished those duty cases from suicide proximate-cause doctrine and declined to extend suicide “special relationship” beyond medical-type contexts.
• Arnett v. Myers, 281 F.3d 552 (6th Cir. 2002)
  Mentioned in a footnote to explain why burden allocation matters at summary judgment; the court ultimately treated suicide foreseeability as part of the plaintiff’s proximate-cause proof burden.

B. Legal Reasoning

1. The controlling substantive test: foreseeability as a probability at the time of alleged negligence

The court applied Tennessee’s proximate-cause formulation requiring proof that the harm was a reasonably foreseeable probability, not merely possible, and that foreseeability is assessed as of the time of the acts or omissions claimed to be negligent. In practical terms, the panel—tracking Cotten v. Wilson—asked whether the defendant should have perceived the decedent as being in an acute suicidal frame of mind or actively contemplating suicide during the relevant window (here, the night before death).

2. Why the evidence did not reach “acute, contemporaneous” suicidality

The plaintiff’s evidence established generalized risk factors: (i) the stepmother knew of a prior suicide attempt by insulin overdose, (ii) she knew he was in therapy, (iii) she participated in a routine to supervise insulin administration, and (iv) she observed persistent poor sleep and depression.

The panel held this was still insufficient under the Cotten framework because it supported, at most, a conclusion that the stepmother perceived a lingering, appreciable, stable risk—not that she should have perceived imminent suicide. The insulin routine, instituted after the earlier attempt “because he was suicidal,” showed caution but did not prove she perceived active contemplation a year later. Likewise, the “identical” sleep pattern across a long period suggested stable depression rather than escalating, time-linked crisis.

3. The deletion of texts: impeachment is not affirmative proof

The court treated the deletion as a specific fact that could undermine credibility (a jury could disbelieve the stepmother’s account). But it held that this did not create a genuine issue on foreseeability at summary judgment because it did not supply affirmative evidence of what the texts said or that they contained suicide threats or other notice-triggering content.

Put differently, even substantial suspicion of spoliation cannot substitute for evidence establishing an essential element; the nonmovant cannot survive by hoping the factfinder will disbelieve the movant and then speculate to the contrary.

4. Superseding cause “collapses” into proximate cause in suicide cases

The panel explained that although superseding cause is generally an affirmative defense in Tennessee, suicide cases are structurally different: because the “intervening act” (suicide) is the very injury complained of, the same foreseeability question governs both proximate cause and superseding cause. As a result, on summary judgment the decisive inquiry becomes whether the plaintiff has evidence that suicide was reasonably foreseeable.

5. “Special relationship” not expanded beyond medical-type relationships for suicide proximate cause

The plaintiff attempted to invoke Tennessee’s “special-relationship exception” historically used to avoid the suicide rule, arguing that step-parent/child or homeowner/household-member relationships should qualify. The panel declined. Reading Cotten v. Wilson as leaving suicide “special relationship” cabined to medical-type contexts, the court refused to assess or recognize new non-medical categories.

C. Impact

• High evidentiary bar for suicide foreseeability in negligent-access-to-firearm cases (Tennessee).
  The decision reinforces that knowledge of prior suicide attempts and generalized depression, even paired with safety routines, may not establish foreseeability absent evidence of contemporaneous escalation, active ideation, threats, or other crisis markers close in time to the alleged negligence.
• Spoliation-style facts may impeach but not necessarily create a triable issue on essential elements.
  The opinion underscores a procedural lesson: credibility attacks (even with troubling deletion conduct) do not automatically satisfy the nonmovant’s burden to produce affirmative evidence of proximate cause at summary judgment.
• Doctrinal clarity after Cotten v. Wilson: “exceptions” remain rhetorically present but do not displace the controlling foreseeability inquiry, and federal courts may be reluctant to expand “special relationship” categories in the suicide proximate-cause context absent Tennessee Supreme Court direction.
• Practical litigation consequences: plaintiffs will likely focus on obtaining (and preserving) concrete, time-specific evidence of ideation (texts, notes, disclosures, clinical records, recent attempts, explicit threats, last-days behavior changes) rather than relying on generalized risk history.

IV. Complex Concepts Simplified

Proximate (legal) cause

A limit on liability: even if conduct contributed in fact, the law imposes liability only for harms that were reasonably foreseeable results of the conduct.

Reasonably foreseeable probability vs. remote possibility

Tennessee requires more than “it could happen.” The evidence must support that the harm was likely enough—given what the defendant knew at the time—that a prudent person would anticipate it as a real probability.

Superseding cause

An intervening act that breaks the chain of legal responsibility. In suicide cases, the intervening act is the injury itself, so the analysis often reduces to whether the suicide was foreseeable.

“Suicide rule” and its evolution

Historically, suicide was treated as automatically severing liability if it was a deliberate choice. Cotten v. Wilson aligns suicide with general tort principles by making foreseeability the central question, while still demanding “solid evidence” because intentional acts are harder to anticipate.

Summary judgment

A pretrial decision for the moving party when the opposing party lacks evidence on an essential element. The court does not decide credibility, but the nonmovant must present affirmative evidence, not speculation.

Impeachment vs. affirmative proof

Showing a witness might be lying does not automatically prove the opposite fact. The court required evidence of what would make suicide foreseeable, not just evidence that the defendant’s account could be untrustworthy.

V. Conclusion

The Sixth Circuit’s decision applies Tennessee’s post-Cotten v. Wilson approach: suicide liability in negligence turns on whether the suicide was a reasonably foreseeable probability at the time of the alleged negligence, with “solid evidence” required to show acute, contemporaneous suicidal risk. The court further clarified that suspicious deletion of communications may undermine credibility but does not, without more, supply the affirmative evidence needed to defeat summary judgment on proximate cause. Finally, the panel refused to extend the suicide “special relationship” concept beyond medical-type relationships, leaving any expansion to Tennessee courts.
