The death of a Montgomery County police officer was ruled a suicide Tuesday, officials said.

According to officials, the Office of the Chief Medical Examiner of the District of Columbia ruled Officer Thomas J. Bomba's death as a result of a self-inflicted injury.

On Monday, Bomba, 38, was found shot on the top level of a parking garage located at Ellsworth Drive and Fenton Street in Silver Spring, police said.

Police said they will continue to evaluate evidence collected at the scene as part of their commitment to completing a thorough and exhaustive investigation.
