D.C. police on Friday charged a 21-year-old man with shooting a Takoma Park teenager once in the head and killing her on a residential street in Northwest Washington.
Authorities described the suspect as an acquaintance of the victim. They said they were still trying to determine a motive and to ascertain the relationship between 18-year-old Siobhan Nicole Lee and Alexander D. Buckley.
Police would not say whether Lee had been visiting the suspect Thursday night or early Friday.
Buckley, of Northwest Washington, was charged with first-degree felony murder. Authorities said they were exploring robbery as a possible reason for the killing.
Lee, who graduated last year from Montgomery Blair High School, was found Friday at 3:24 a.m. by a patrol officer responding to a call of an unconscious person lying on a sidewalk in the 5700 block of Fifth Street NW in the Brightwood neighborhood. Police said she was pronounced dead at the scene.
