An active duty Marine based in Camp Pendleton seen lying on the freeway was struck and killed by a car early Sunday morning.
The 28-year-old man, who has not been identified, was seen lying across the number one lane of westbound Interstate 8 in the College Area of San Diego, east of Mission Valley, at approximately 3:21 a.m., according to the Medical Examiner's office.
The man was hit by at least two cars, California Highway Patrol (CHP) officers said.
The driver or one car left the scene, officers said.
Then, a Sedan approaching the lane early Sunday morning was unable to stop after seeing him, and struck him, according to the ME's office.
The driver called 911 after the collision, the ME said. Once first responders arrived, they pronounced the man dead at the scene.
CHP officers say they do not know why the man was on the freeway in the first place. They do not believe his car was broken down, as there was no car in the area.
The investigation is ongoing. Officers are asking anyone who may have witnessed the collision or unknowingly been a part of it to come forward and call them.
