United States v. Butler

Man is convicted of 1970 Washington, D.C. murder on the strength of testimony from two friends who said he confessed and an FBI agent’s hair microscopy analysis, the latter of which the FBI now admits is junk science. (The man escapes from prison in 1978 and isn’t recaptured until 2006.) Set aside his murder conviction? Indeed, says two-thirds of a D.C. Circuit panel: As we said when we first reviewed the case in 1973, the friends were quite likely unreliable. So the hair evidence was material.
