Ralph Eldridge v. City of Warren, MI
655 F. App'x 345
| 6th Cir. | 2016Background
- On June 18, 2009, Warren officers Patrick Moore and Robert Horlocker tasered and arrested Ralph Eldridge, a diabetic who was experiencing hypoglycemia; officers later found an insulin pump and called an ambulance.
- Eldridge sued under 42 U.S.C. § 1983 alleging Fourth Amendment excessive force against Moore and Horlocker and Monell municipal liability against the City of Warren for failure to train.
- Defendants sought to exclude prior-act evidence; the district court initially allowed non-lethal force reports but later, under a new judge, excluded a video showing Moore tasering a different, apparently noncompliant detainee.
- At trial the jury found no excessive force by Moore or Horlocker; because no constitutional violation was found, the municipal liability claim was not reached.
- Eldridge appealed arguing the prior-taser-use video should have been admitted to show absence of mistake or modus operandi; the Sixth Circuit affirmed exclusion under Federal Rules of Evidence 404(b) and 403.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of video under Rule 404(b) for absence of mistake | Video shows Moore’s prior taser use evidencing absence of mistake about tasering Eldridge or officers’ knowledge | Video is improper prior-act evidence and not probative of mistake or knowledge about Eldridge’s medical condition | Excluded: not a proper 404(b) purpose; plaintiff failed to show how video proves absence of mistake |
| Admissibility as modus operandi (identity issue) | Video shows a consistent pattern/signature in Moore’s taser use | Identity is not at issue; taser deployments lack a striking, distinctive signature | Excluded: modus operandi inapplicable and similarity not sufficiently distinctive |
| 403 balancing — probative value vs. unfair prejudice | Probative value relevant to Monell and individual claims | Video’s prejudicial effect outweighs probative value and risks jury conflation | Excluded under Rule 403 as unfairly prejudicial |
| Effect on Monell claim if video excluded | Video necessary to prove municipal custom/policy or absence of mistake | Even if admitted, video alone insufficient to establish municipal policy; exclusion proper | Court affirmed exclusion; municipal claim moot because no constitutional violation was found |
