Three people killed, four injured as jet ski collides with boat

Three women were killed Saturday afternoon in San Dimas when their jet ski crashed into a powerboat, injuring four others, authorities said.

The collision between the Sea-Doo watercraft and the boat occurred about 4:30 p.m. in Puddingstone Reservoir at Frank G. Bonelli Regional Park, said Matt Levesque, a Los Angeles County Fire Department inspector.

"It was a pretty severe accident in the middle of the water," Levesque said.

The three victims killed -- ages 25, 35 and 60 -- were not identified, he said. They were pronounced dead at the scene.

Three male occupants on the boat -- ages 22, 35 and 36 -- suffered critical injuries and were taken by helicopter to a trauma center, Levesque said. A 22-year-old female passenger suffered minor injuries.

The crash is being investigated by the Los Angeles County Sheriff's Department and the Parks and Recreation Department.

"It was a tragic, tragic accident," said Imee Perius, a spokeswoman for the parks department.
