A man's body was found floating in Lake Washington this afternoon near Bellevue, and authorities are trying to determine how he got there.

The body was discovered by a 12-year-old girl in the Pleasure Point Lane area, in the southwest corner of Bellevue.

The body, of unknown age and race, is wearing rain gear and apparently has been in the water between 24 and 48 hours, police said.

Officials said it’s hard to tell where the man might have been carried from, due to wave action.

There are no obvious signs of trauma on the body, but an autopsy will be performed to determine the probable cause of death.
