Anthony Keith Thurman was 24 when he was beaten to death with a pipe in Portland, Oregon. The attack occurred on April 5, 1990; his body was found later that month discarded beneath the concrete of a freeway overpass. Thurman was African American and, at the time of his death, part of a pattern of violence affecting transient populations.

Investigators later linked Thurman’s killing to a series of similar murders spanning several states. Authorities identified Andrew David Edwards as the suspect; Edwards, described as a jobless drifter, reportedly targeted other transients in alcohol-fueled attacks beginning as early as 1987. Edwards was arrested after an attempted murder in San Jose, California, in January 1993 and confessed to Thurman’s killing.

Did anyone who knew Anthony Thurman or who was in Portland that spring of 1990 notice anything out of the ordinary around April 5?
