(Portland, OR) -- An autopsy is scheduled tomorrow for a body believed to be that of one of the three missing Hart children. Police in Northern California say some tourists found the body Saturday afternoon floating in the surf near Juan Creek in Mendocino County. Police say the body appears to be that of a black female. Search crews are still looking for three children who are missing after Jennifer and Sarah Hart crashed their car off a cliff along the coast two weeks ago, killing themselves and at least three of their children. Police believe all six of their children were in the car at the time of the crash.
