The county medical examiner's office has identified a motorcyclist killed in a crash in Miramar Friday afternoon.

San Diego resident Jason Lee Hansen, 42, was killed in an accident with a truck just before 2:30 p.m. in the 8400-block of Miramar Road, in front of the Flying Leatherneck Aviation Museum.

According to officials, Hansen was traveling westbound on his Harley Davidson when a Chevy ST pickup truck crossed into Hansen's lane. The truck collided with the motorcycle, and Hansen did not survive the crash.

Witnesses called 911. When first responders arrived, they pronounced Hansen dead at the scene.

A medical examiner's report released Friday night says Hansen leaves behind a wife and daughters.

The accident is under investigation.

Following the collision, authorities issued a SigAlert and temporarily shut down Miramar Road between Camino Ruiz and Cabot Drive. Traffic backed up Miramar Road for hours, and drivers were asked to completely avoid the area if possible.
