Prince George's County police say homicide suspect is ‘armed and dangerous'

Prince George's County police are searching a man suspected of shooting two people - and killing one - at a home in Lanham early Sunday morning.

They say 20-year-old Osman Kalokah of the 12000 block of Quince Valley Drive in North Potomac should be considered armed and dangerous.

Police began investigating shortly before 3 a.m. when they responded to a home in the 9000 block of Alcona Street after a reported shooting.

They found two people suffering from gunshot wounds - a man and a woman.

The man - 69-year-old Alee Calokoh - was pronounced dead the scene.

Calokoh is the suspect's uncle.

A woman was taken to a local hospital. Police do not believe her injuries are life threatening.

Investigators believe the pair were shot during an argument before the shooting.

If you see Kalokoh, call 911.
