113 A.3d 564
D.C.2015Background
- Defendant Charles Coates was convicted of second-degree murder while armed and related firearm offenses after admitting he shot his cousin Eddie Leonard but claiming it was accidental/self-defense during a PCP-induced episode. The prosecution’s key evidence of an intentional killing was testimony from jailhouse informant Robert Bethea that Coates confessed to killing Leonard in a dispute over robbery proceeds.
- Bethea had an extensive criminal history and a record of cooperating with prosecutors in multiple homicide cases in exchange for substantial benefits; his testimony was uncorroborated and pivotal to the government’s theory.
- Defense presented an alternative account: Leonard, high on PCP, became violent, drew his gun, and the weapon discharged during a struggle; toxicology supported PCP use and only Coates saw the shooting.
- Defense attempted to impeach Bethea for corruption/bias by introducing evidence that Bethea previously reported another inmate, Travis Freeman, had confessed to a different murder—and the government acknowledged Freeman could not have committed that murder—yet the trial court barred proof (stipulation or other evidence) of Freeman’s factual impossibility to have committed the crime.
- The trial court admitted as extrinsic evidence a videotaped statement by Coates describing uncharged "trick" robberies to attack his veracity; defense objected under the rule prohibiting extrinsic proof of prior bad acts not resulting in conviction.
- The D.C. Court of Appeals held both evidentiary rulings erroneous, found the restriction on bias impeachment violative of Coates’s Sixth Amendment confrontation right and not harmless, and vacated convictions and remanded for a new trial; it also ruled the extrinsic-admission impeachment was improper.
Issues
| Issue | Plaintiff's Argument (Coates) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| 1. Whether court erred by excluding proof that Freeman could not have committed the prior murder Bethea said Freeman confessed to (bias impeachment of informant) | Coates: Excluding evidence that Freeman was physically incapable of committing the murder foreclosed the strongest proof of Bethea’s corruption/bias and violated his Confrontation Clause right to probe a crucial witness’s motives. | Government: The fact Freeman was innocent does not prove Bethea lied—Freeman could have falsely boasted—so proof of Freeman’s innocence is collateral and irrelevant. | Court: Error. Evidence of Freeman’s impossibility to have committed the murder was relevant to show Bethea’s corruption/bias; exclusion violated Confrontation Clause and was not harmless. |
| 2. Whether prosecutor could impeach Coates’s veracity with extrinsic evidence of prior uncharged “trick” robberies (videotaped confession) | Coates: Extrinsic evidence of prior bad acts not resulting in conviction cannot be used to attack witness credibility; only cross-examination is allowed and then only with a factual predicate; Sherer prohibits extrinsic proof. | Government: Statements were admissible to show dishonesty and assist jury in assessing credibility (and argued they evidenced consciousness of guilt). | Court: Error. Admission and use as extrinsic proof to attack truthfulness violated rule barring extrinsic proof of uncharged prior misconduct; such evidence cannot be used in prosecution’s case-in-chief to impeach veracity. |
