The driver of a speeding pickup truck who lost control and crashed into a tree, killing two teenage passengers, has been released from the hospital and arrested.

Jared Berggren, 19, of Fullerton, was released Monday night from UCI Medical Center in Orange after being treated for head injuries, police said. Berggren was booked at the Orange County Jail on suspicion of two felony counts of gross vehicular manslaughter and one count of felony drunken driving, with a sentencing enhancement for causing great bodily injury. He is being held in lieu of $500,000 bail.

Jacquelyn A. Ardalan, 19, of La Habra, and Miles A. Christensen, 19, of Fullerton were ejected from the 2006 Toyota Tacoma that Berggren was driving, authorities said. They were pronounced dead at the scene.

The accident occurred around 2:30 a.m. Monday as the blue pickup truck was speeding eastbound on Coyote Hills Drive, west of Gilbert Street, and lost control, said Fullerton police Sgt. Mike MacDonald.

After losing control, the pickup started to skid, went off the road, flew up a hill and struck a Eucalyptus tree, which sheared off the top of the truck, MacDonald said.

It appears the teens were drinking in a cul-de-sac on Coyote Hills Drive where officers later found beer cans, MacDonald said.

Police are investigating where the teens got the alcohol.
