Search and Rescue teams covered 32 miles of Mendocino County coastline Wednesday morning but found no clue about the fate of three children missing since their family’s SUV was found half-submerged and upside down on tidal rocks north of Westport March 26.

Jennifer and Sarah Hart and three of their adopted children, Markis, 19, Abigail, 14, and Jeremiah, 14, died in the crash that authorities say happened sometime between 9 p.m. March 25 and 3 p.m. March 26, when a motorist who pulled over at a wide turnout along a remote stretch of Highway 1 spotted the Hart’s wrecked vehicle in the surf below.

A search right after the crash discovery, and a much broader effort Wednesday starting around 6:30 a.m. to take advantage of low tide, found no sign of three other Hart children, Sierra, 12, Hannah, 16; and Devonte, 15.

California Highway Patrol investigators believe the Harts were in Newport, Oregon on the morning of March 24, travelled south along the California coast, and spent time in Fort Bragg that night. The CHP identified Jennifer Hart in surveillance video taken at the Safeway grocery store in Fort Bragg March 25 about 8:15 p.m. and investigators believe they were in the Fort Bragg and Cleone areas until about 9 p.m. that night. Their car was discovered mid-afternoon the next day.

Lt. Shannon Barney of the Mendocino County Sheriff’s Office said Wednesday’s search, which included one state and seven Northern California county search and rescue teams, 74 people in all, divided into 16 groups that combed two stretches of rocky shoreline. A California Highway Patrol helicopter, but no watercraft, joined the effort as well,

One search area covered about 28 miles between Noyo Harbor in Fort Bragg and the crash site at Juan Creek north of Westport. Another, 45 miles south of Fort Bragg, covered around eight miles of coastline between the mouth of the Garcia River and Manchester State Park near the town of Elk.

The search areas were determined by ocean current estimates provided by the U.S. Coast Guard, according to Barney.

Barney said a dive team went into the water near Westport Wedneday morning not far from the crash site, where a resident reported seeing a bright object in the water that might have been clothing. Divers searched a 250-by-400 yard area with good underwater visibility, Barney said, but found nothing.

There are no plans to continue the large-scale search effort, according to Barney, which he said should now be termed “search and recovery” nearly ten days after the crash. Wet weather expected over the next few days, and a lack of evidence relating to the three unaccounted-for children has suspended the search for now, he said, with the main effort at piecing together the circumstances leading up to the crash being done by the California Highway Patrol. The CHP is exploring the possibility that the three missing Hart children weren’t with the rest of the family at the time of the crash, but investigators say they have no reason to believe they weren’t also in the vehicle.

The CHP asked Tuesday that anyone with information related to the Hart family’s travel, stops along the way, people they may have encountered, or any information about the family call the California Highway Patrol – Ukiah Area office at (707) 467-4000 or the Mendocino County Sheriff’s Office at (707) 463-4086.
