The following article was in the paper yesterday: Boy dies after dirt-bike collision Accident - His father, riding a motorcycle up the opposite side of a sand dune, strikes the Aliso Viejo teen, who dies after surgery A 14-year-old Aliso Viejo boy was killed in an off-road motorcycle accident Sunday morning when he collided head-on with a motorcycle driven by his father just out-side Anza-Borrego Desert State Park in San Diego County. Jesse Davis, an eighth grader at Don Juan Avila Middle School and avid motorcyclist, later died at a hospital after surgery. ?They weren?t able to see each other because they approached the same hill from different directions,? said Jose Rocha, a dispatcher with the California Highway Patrol in San Diego. The accident occurred at 10:30 a.m. at the Ocotillo Wells State Vehicular Recreation Area, a massive desert park with sand dunes about 100 miles northeast of San Diego. The boy?s father, Steven Gonzalez, 40, of Aliso Viejo was riding a Yamaha YZ 125 at 40 mph up a dune, while his son, also on a motorcycle, approached the same hill from the opposite direction at about 20 mph, the dispatcher said. The father jumped his bike at the top of the hill and crashed into his son?s upper body as he reached the top of the sand dune, Rocha said. The boy was knocked unconscious; he was flown to Palomar Medical Center. He died after undergoing emergency surgery, said Tamara Hemmerly, a hospital spokeswoman. Gonzalez was treated at Pioneer Memorial Hospital in Brawley. The U.S. Consumer Product Safety Commission reported that there are more serious injuries and fatalities involving off-road motorbikes than in more common sports, but there are no statistics on dirtbike accidents and fatalities. Neighbors on Sunday night recalled the love of motorcycles shared by father and son. The pair often rode together in front of their house on Plateau Street. ?That?s all he wanted to talk about,? said friend Katie Graves, 13. "He did dirt biking and won trophies.? The girl said she last saw Jesse on Friday night. He was excited about the weekend family camping trip. She said Jesse enjoyed making milkshakes, listening to punk and rock music, and riding his skateboard. ?He was really sweet? she said. ?He liked to show everyone his bikes and his room.? Katie?s mother, Jennifer Graves, said Jesse had a happy disposition and lots of friends. ?He was always very nice to Katie,? Graves said. ?They talked on the phone almost every day.?
