Baltimore man tried four times for same killing sees all charges dropped

Keith Davis, 31, shot by police, was repeatedly charged over shooting at Pimlico race track in June 2015

A Baltimore man who stood trial four times for the same killing had all charges against him dropped on Friday.

In a statement, the Baltimore state attorney, Ivan J Bates, said his office had dismissed all charges against Keith Davis, 31, who was accused of the 2015 killing of Kevin Jones, a security guard at Pimlico Race Course, after police alleged Davis's gun matched casings found at the scene of the shooting.
