A 39-year-old man died when his sedan slammed into the back of a motorhome on Interstate 215 in Riverside, authorities said Thursday.

Cory McClanahan of Riverside died about 11:30 p.m. Wednesday on southbound I-215 near University Avenue.

He was in the No. 3 lane of the five-lane corridor “traveling at a high rate of speed,” when he plowed into the rear of the RV, said Riverside Fire Department Capt. Jeremy Roberts.

“The impact trapped the driver in his vehicle, which was partially pinned under the motorhome,” Roberts said.

No RV occupants were injured.

Two engine crews and a truck company were sent to the crash, and firefighters used industrial cutting equipment to free McLanahan, peeling back the roof of the mid-size sedan to extricate him, Roberts said.

“The patient died at the scene,” he said.

California Highway Patrol officers partially closed southbound I-215 to remove the wreckage and conduct a preliminary investigation. The freeway was fully reopened within four hours.

Anyone with information was asked to contact the CHP’s Riverside office at 951-637-8000.
