A 22-year-old San Diego man killed in an Otay Mesa crash over the weekend was thrown from his car and then run over and dragged by at least one other vehicle after his own car struck a tree, split in half and burst into flames, authorities said Wednesday.

Brian Isaac Lopez Ames was driving from southbound Interstate 805 to westbound state Route 905 around 1:55 a.m. on Saturday when, for unknown reasons, he left the roadway and his car struck a large tree, the San Diego County Medical Examiner’s Office said.

“The vehicle then split in two and he was ejected,” the medical examiner’s office said in a statement, noting that the rear half of the car remained near the tree, where it became fully engulfed in flames and sparked a small blaze in the nearby brush. The front end of the car ended up in the median south of westbound SR-905.

Lopez Ames was thrown onto the highway, where he was apparently struck and run over by at least one other vehicle and dragged along the right lane of SR-905, the medical examiner’s office said. Several motorists stopped and called 911, but Lopez Ames was pronounced dead at the scene without medical intervention “due to obvious fatal trauma.”

His cause of death was listed as multiple blunt force injuries.
