Fresno police have identified the man found dead at a North Fresno park over the weekend. Park goers found the body floating in the park's biggest lake about 15-feet from the shore.

Police said the man is 19-year old Brian Dhuyvetter. Investigators said he wasn't in the water long.

"I think the biggest challenge is make sure that we accurately determine what caused this death and then if there is someone to be held responsible that we find out who that is," said Lt. Tony Bennink with the Fresno Police Department.

The autopsy for Brian Dhuyvetter will be performed Monday afternoon.
