A 24-year-old Yakima man died Wednesday after his car careened off Interstate 5 and sank upside down in a Federal Way retention pond, according to the Washington State Patrol.
Drivers started calling 911 about 5:30 a.m. to report a 1995 Honda Passport driving erratically.
By the time troopers arrived, the man’s car was in five feet of water in an icy retention pond near southbound I-5 and South 320th Street.
A helicopter flew overhead to detect heat sources that would indicate whether someone was in the car. A dive team recovered the man’s body.
He was pronounced dead at the scene.
Shortly before he crashed through a guard rail into the retention pond and drowned, the man posted on a social media account that he was going to take his own life, Sgt. Chris Walker said.
The driver has not been identified.
