An 18-year-old man was fatally shot in the backyard of his home early Saturday in the Burtonsville area of Montgomery County during an encounter with one or more armed individuals, according to police.

Authorities identified the victim as Damion Callery Jr.

Police said they responded about 3:45 a.m. for a report of a shooting in the 14100 block of Angelton Terrace.

The rowhouse is in a cluster of eight other attached residences on a circular drive east of Columbia Pike and near the Fairland Recreational Park. Police initially said they believed the shooting had occurred inside the house but later said it happened outside. They said the wounded Callery ran inside, where he was found dead.

No arrests have been made. Police did not comment further on the case.
