FINKSBURG, Md. (AP) - Two teenagers are dead after a one-vehicle crash in Finksburg.

State police have identified the victims of Saturday night's crash as 15-year-old Emily Burke of Sykesville and 14-year-old Rudolfo Calderon of Finksburg. Both were pronounced dead at the scene.

Police say the two victims were passengers in a van being driven by 17-year-old Paul Burke, Emily's brother. He was driving his sister, Calderon and another passenger, 15-year-old Alison Hird, to their homes when he lost control of the van on Louisville Road and hit a tree.

Paul Burke and Hird were taken to Shock Trauma for treatment. Police say it's possible Burke fell asleep at the wheel, and there was no immediate indication of alcohol or drug use.
