Portland police advertise cold cases on buses



PORTLAND, Ore. (AP) — Portland police are trying something new to crack cold cases: a publicity campaign on TriMet buses.

The police bureau was announcing the the bus billboard campaign Friday. One of the first cases being advertised is that of Brian Todd Mitchell, who was killed in November 1995 in northeast Portland.

Portland police have nearly 300 unsolved homicides dating back to 1969. The department’s cold-case unit comprises a sergeant, four detectives and several retired investigators who are paid by a federal Justice Department grant.
