BALTIMORE (AP) — Charges have been dropped against a Baltimore man accused of killing an off-duty Maryland Transit Administration bus driver.

Thirty-four-year-old Kevin Carroll had been charged with first-degree murder in the February shooting death of bus driver Craig Ray in a dispute over loud music in south Baltimore.

Court records show prosecutors dropped all charges against Carroll on Sept. 15.

Carroll’s attorney, Lawrence Rosenberg, said Thursday that phone records and other evidence proved Carroll was on the other side of town with his girlfriend at the time of the killing. He says his client has maintained his innocence all along and is ecstatic about being released from jail.

Baltimore police say the investigation into Ray’s killing was closed after Carroll’s arrest and weren’t able to immediately say whether it would be reopened.
