SAN DIEGO -- Carlsbad police said Sunday they are investigating the claims of a motorist, who says she may have unwittingly struck a teenaged boy on El Camino Real, but left the scene after failing to spot any victim.

Steven Anthony Kelley, 18, suffered mortal injuries around 9:45 p.m. Friday when he was struck by two vehicles on El Camino Real near Cassia Avenue. He died in an ambulance en-route to McClellan-Palomar Airport, where he was to be flown to a hospital, according to police.

Officers had stopped one car's driver near the scene, but the first vehicle that struck Kelley kept going.

On Saturday, Lisa Hutchinson, 44, came forward as the driver of one of two cars that may have struck the youth, said Carlsbad police Lt. Jarlath Eppel. The lieutenant said Hutchinson told officers she drove home and told her husband that she had hit something with her vehicle on El Camino Real, and both people returned to the area but couldn't find anything when they returned to the area.

Traffic investigators went to their house, took a statement from the woman and impounded her car, he said

Eppel said police will turn their case over to the District Attorney's Office, where prosecutors will determine whether to charge her in the death.

Police asked anyone with more information was urged to call them at (760) 931-2197.
