(Mendocino County, CA)  --  The California Highway Patrol says an SUV submerged in a Mendocino County river matches a vehicle belonging to a missing family.  The Thottapilly family was traveling from Portland to San Jose when a concerned relative told police they hadn't shown up on Sunday as expected.  Witnesses reported seeing a vehicle going over an embankment off Highway 101 near Dora Creek and the wreckage matched the description of the Thottapilly family vehicle.  Rescue crews are now searching the creek for any sign of the family.
