A man was fatally shot inside his Seat Pleasant home Tuesday night in an apparent home invasion robbery, and investigators are exploring whether he might have been targeted for money he made working as a tattoo artist, law enforcement officials said.

The officials, speaking on the condition of anonymity because they were not authorized to release details of the case, said 23-year-old Michael Nolan Brown did tattoo work out of his home, and detectives were probing whether someone might have tried to rob him for money made in that business. The officials said that was only one theory, though, and they were still exploring others that might explain why Brown was shot.

The incident occurred about 10:15 p.m. inside Brown’s home at 606 Cabin Branch Drive. Lt. William Alexander, a Prince George’s County police spokesman, said more than one person made their way into Brown’s home and demanded money. That sparked a confrontation in which Brown was shot, Alexander said.

Alexander said police were seeking suspects in the case.
