Estate of Eric Jack Logan v. City of South Bend, 50 F.4th 614

At ~3:30 a.m. Officer Ryan O’Neill investigated reports of items being stolen from parked cars and encountered Eric Jack Logan, who picked up a hunting knife and approached O’Neill.
O’Neill ordered Logan to drop the knife, stand still, and get down; Logan ignored commands, held the knife up, advanced within a few steps, and then threw the knife, striking O’Neill’s arm. O’Neill shot Logan; Logan later died.
The Estate sued under 42 U.S.C. § 1983 claiming excessive deadly force in violation of the Fourth Amendment; the district court granted summary judgment for O’Neill and the City.
The Estate does not dispute many core facts but argues O’Neill’s varying descriptions could mean Logan threw the knife before O’Neill fired (so O’Neill was no longer in danger) and points to delayed bodycam activation and O’Neill’s felony (ghost employment) conviction to attack credibility.
The court emphasized that when the officer is the lone surviving witness, plaintiffs need independent physical evidence to contradict the officer’s account; here the physical evidence (e.g., bullet track) is consistent with O’Neill’s version.
The court held that a reasonable officer could conclude the threat persisted (knife plus possible concealed weapons and Logan’s size/advance), and disbelief of the sole witness without independent proof cannot overcome summary judgment.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether O’Neill used excessive (deadly) force in violation of the Fourth Amendment	Logan threw the knife before O’Neill fired, so O’Neill was no longer in danger and deadly force was unreasonable	O’Neill reasonably perceived an ongoing threat: Logan had a knife, advanced after ignoring commands, could have other weapons or used hands/feet, and remained dangerous when shot	Court held force was reasonable; even on the Estate’s favored sequence a jury could not find O’Neill was out of danger before shooting
Whether credibility challenges (inconsistent statements, delayed bodycam, felony conviction) create a genuine issue of material fact to survive summary judgment	The inconsistencies, late bodycam activation, and O’Neill’s conviction undercut his credibility and warrant a jury trial	Credibility attacks alone, without independent contradictory evidence, cannot defeat summary judgment; physical evidence aligns with O’Neill’s account	Court held credibility challenges insufficient; plaintiff failed to produce independent facts to create a triable issue
