A teenager who graduated from Gonzaga College High School last month was fatally shot in Bethesda late Sunday in what Montgomery County police called a drug-related incident.

Bijan Manuel Nassirdaftari, 17, of Bethesda was found at Alta Vista Road and Alta Vista Terrace. He was pronounced dead at the scene by Montgomery emergency officials.

Residents nearby reported shots shortly after 11 p.m. Sunday. When officers arrived, they found Nassirdaftari.

Police said a preliminary investigation determined that Nassirdaftari was shot "during a drug-related incident." Police spokesman Eric Burnett would not provide more specific information.

Nassirdaftari's family, of the 7100 block of Plantation Lane, declined to comment. Officials at Gonzaga, in the District, confirmed that he graduated from the school in June but had no further statement.

Nassirdaftari's death marks the second fatal shooting in less than six weeks of a recent high school graduate in an apparent drug incident. Last month, Ezekiel Oak Babendreier, 18, a graduate of Damascus High School, was fatally stabbed after what police say was a conversation about buying marijuana outside a Germantown birthday party. Two teenagers have been charged in his killing.

Babendreier's killing came a week after two teenagers suffered gunshot wounds in a fight at a party in eastern Montgomery County.

Residents of the Bethesda neighborhood where Nassirdaftari was killed expressed shock that the crime took place so close to their homes, in a heavily wooded neighborhood where American flags adorn patches of grass near the curb.

Oscar Nunez, a student at the French International School in Bethesda who lives on Alta Vista Court, said he returned home about midnight Sunday to find emergency vehicles parked near his house.

"Right now I don't know what to say or think," said Nunez, 17. "The part that's really scary is I always walk these roads alone."

Marianne Ducout, who has lived on Alta Vista Court about a year, said the event is uncharacteristic for her calm neighborhood.

"I feel quite safe," Ducout said. "It's surprising. What else can I say?"
