PITTSBURGH (AP) – A man has been sentenced to a mandatory term of life in prison without possibility of parole in the death of a teenage girl shot on a Pittsburgh street in what authorities called a drug deal gone wrong.

The Pittsburgh Post-Gazette reports that 20-year-old Douglas Lockett Jr. was sentenced Monday on second-degree murder and robbery convictions in the death of 17-year-old Daija McCall.

Allegheny County prosecutors said she was meeting three men for a purported drug sale in the city’s Homewood section in September 2016, but they planned to rob her. Tests later concluded the substance she was carrying didn’t contain drugs.

Police said she was armed and fired three shots while two other guns fired eight shots. Defense attorney Randall McKinney denied that his client planned a robbery.
