SALTON CITY, Calif. -

Authorities are looking for help to find an 87-year-old Salton City man who's been missing since Saturday.

Jim Baker was last seen by his daughter at his home on Harlequin Court at around 10:30 a.m. Saturday morning.
He was wearing a tan T-shirt and tan shorts.
Along with Baker, his 2008 white Toyota Scion disappeared sometime during the day.
