Prince George’s County, Maryland, police have arrested a teenager they believe murdered a family member earlier this month.

Police said Jammi Cooper, 36, was killed in a shooting on Oct. 5, at around 10:50 p.m. while in the unincorporated portion of Capitol Heights. Both he and the teen are residents of the District.

Preliminarily, investigators believe that the teen — an unidentified 17-year-old male — was in a dispute with Cooper when the shooting occurred.

The teen was arrested in D.C. and charged with first- and second-degree murder in relation to this shooting. Officials said that he is awaiting extradition to Prince George’s County to face those charges and will be charged as an adult.
