Police say a young mother was killed and a man was hurt when they were struck by a vehicle on Montauk Highway in Eastport last night, and now the search is on for the driver who fled the scene.

Investigators say 27-year-old Erika Strebel, of Eastport, was struck at around 9 p.m. after she pulled her Jeep onto the shoulder due to car trouble. She was taken to Peconic Bay Medical Center, where she was pronounced dead.

Strebel's companion, Edward Barton, suffered head and leg injuries. He is being treated at Stony Brook University Medical Center.

Strebel leaves behind a 5-year-old son, named Ayden. Devastated friends and relatives have set up a Facebook page honoring her memory, and flowers have been placed at the spot where the crash happened.

Police say they are looking for a large vehicle with front-end damage that is believed to be metallic blue in color. The vehicle left the scene heading east on Montauk Highway.

Anyone with information is being urged to call Crime Stoppers at 1-800-220-TIPS.
