A Solana Beach man was behind bars Thursday on suspicion of fleeing on foot after his car hit and killed a young man changing a tire alongside a South Bay freeway.

A southbound Dodge Stratus struck 21-year-old Raymart Agsalon Martos of Imperial Beach in a center median on Interstate 5 near Mile of Cars Way in National City about 5:30 a.m. Tuesday, then crashed into a divider wall, according to the California Highway Patrol.

Martos died at the scene.

The driver of the Dodge, later identified as 29-year-old Christopher Ramirez Reyes, allegedly abandoned his car and ran off, CHP public-affairs Officer Tony Contreras said.

Investigators tracked down Reyes and arrested him the following evening on suspicion of hit-and-run causing injury or death.

He was being held at San Diego Central Jail on $50,000 bail pending arraignment, scheduled for Friday afternoon.
