LOS ANGELES , California ( CNN ) -- Paint markings found on pieces of two planes that collided over suburban Los Angeles indicate the nose of one aircraft slammed into the middle fuselage of the other , according to a federal investigator . Investigators on Monday walk past the tail section of a plane lying in a car dealership . Five people died in the accident in Corona , California , including a man on the ground who was killed when one plane 's engine crashed through the roof of a car dealership where he worked , said National Transportation Safety Board investigator Wayne Pollack . The NTSB , assisted by FBI evidence experts , completed the cleanup of wreckage and body parts that were spread over a commercial area of car dealerships , restaurants and other businesses near the Riverside Freeway Monday afternoon . Investigators do n't yet know if both single-engine planes were approaching the nearby Corona airport for landing , but it was apparently a Sunday afternoon pleasure flight for each . The two men in the Cessna 150 were ejected after the plane was struck broadside by the Cessna 172 , Pollack said . The bodies of the two men flying in the Cessna 172 were found inside the plane after it crashed to the ground , he said . The FBI helped the NTSB mark where each piece was found , although the investigation does not involve any criminal aspect , Pollack said . The wreckage was being trucked to Palmdale , California , Monday evening . Aviation experts there will examine it for more clues about what caused the collision , he said . There were two licensed pilots on board the Cessna 150 , which was rented from a local flight school , Pollack said . One of the two people on board the other plane -- a Cessna 172 -- was licensed to fly , he said . The victims from one plane were identified as Scott Lawrence , 55 , and Paul Carlson , 73 , both from Cerritos , California . The dead from the other aircraft were Brandon Johnson , 24 , from Costa Mesa , California . and Anthony Guzman , 20 , from Hesperia , Calif. , according to the Riverside County Coroner 's Office . The car dealership employee who died was Earl Smiddy , 58 , from Moreno Valley , California , the coroner said .
