Detectives in Prince George’s County canvassed an Adelphi neighborhood Saturday as part of their probe into the murder a 22-year-old the night before.

Mamadou Bah was found at 7:25 p.m. Friday in the 1800 block of Metzerott Road, according to Prince George’s police officials. He had been shot several times.

He was pronounced dead at the scene.

“Detectives are actively working [to] find out who killed Mamadou and why,” Maj. Brian Reilly, commander of the county’s Criminal Investigation Division, said in a statement released by police. “What we know so far is the 22-year-old worked as a delivery driver and had only lived at the apartment on Metzerott Road for two weeks. Mamadou is from Guinea and we’re told he came to the country to attend school.”

Reilly said detectives had not discovered a motive or identified anyone who may have wanted to hurt Bah.
