Authorities said that a note was found in Scott's black Prius listing contact information. Investigators later found a suicide note at his office, according to the Los Angeles Times.
A joint task force of LAPD, California Highway Patrol, firefighters and the Coast Guard recovered his body from the water at approximately 3 p.m.
"It's a dolorous task and we're working to treat the deceased with the utmost dignity and respect," Los Angeles Fire Department spokesman Brian Humphrey said.
