BALTIMORE, Md. - Baltimore Interim Police Commissioner Gary Tuggle has fired an officer after he was charged with a DUI while on duty.

According to police, Southern District supervisors found Officer Aaron Heilman slumped behind the wheel of his running patrol car Tuesday afternoon.

They say that he was working three hours into his overtime shift of crime suppression in that area when he was found in his marked vehicle.

Supervisors at the scene immediately transported the officer to the Central District due to their suspicion that he was intoxicated.

Heilman gave consent to a breathalyzer and blew a .22 Blood Alchohol Content (BAC). A .08 BAC is the legal limit for a DUI in Maryland.

He was cited and Interim Commissioner Tuggle terminated him on Wednesday.
