A man was killed Saturday when his Cadillac Escalade overturned and crashed into a tree on the Sea World Drive on-ramp to northbound Interstate 5, the California Highway Patrol said.

The accident happened about 9 a.m. when the white luxury SUV, traveling at a high rate of speed according to one witness, overturned and hit a tree on the right shoulder of the on-ramp, according to CHP Officer Salvador Castro.

Units from the San Diego Fire-Rescue Department were also on the scene, near the Tecolote Canyon Natural Park and Nature Center.

The CHP had no immediate information on the identity of the victim. Castro said nobody else was in the SUV at the time of the crash.
