Authorities today identified the boy killed in Saturday's personal watercraft crash at Alcova Reservoir as 11-year-old Brenton McCullar of Evansville.

McCullar was driving a Yamaha watercraft when it collided with a speed boat near the Oakie Beach region of the lake, said Natrona County Sheriff's Sgt. Mark Sellers. The boy was flown to Wyoming Medical Center in Casper where he was pronounced dead.

A 30-year-old man, whom authorities did not identify, was riding with McCullar. He was also taken to the hospital for treatment. An update on his condition was not available.

Sellers said the man was a family friend.

None of the people in the boat were injured.

The sheriff's office and Wyoming Game and Fish are investigating the cause of the collision. Once the investigation is complete, it will be forwarded to the Natrona County District Attorney's Office.
