A dirt bike rider was killed in a crash Tuesday afternoon at the Slayground Motocross Park, a private motocross facility near Sutherland Dam Road, east of Ramona.
The 29-year-old rider performed a jump but missed his landing and the motorcycle appeared to fall on top of them, CHP Officer Jared Grieshaber said.
Witnesses at the facility, who reported the crash at around 3 p.m., gave the rider CPR until they were relieved by emergency responders, who continued CPR until about 3:40 p.m. when the rider was pronounced dead, according to Cal Fire San Diego spokesperson Brent Pascua.
The facility is privately owned by Encinitas-native motocross rider Axell Hodges and is regularly used for motocross training as well as some X Games events, according to the X Games website.

Because the collision occurred on private property, the collision and related death would be investigated by the San Diego County Sheriff's Department.
