LEGGETT, Calif. - Recovered vehicle debris and personal items confirm that an SUV seen plunging into a storm-swollen Northern California river belonged to a family that disappeared last week, authorities said Thursday.

The vehicle itself and the four members of the Thottapilly family have not been recovered from the Eel River, which remains too dangerous for divers to enter, but searchers along the banks located numerous items consistent with a Honda vehicle and interior, and items consistent with a family travelling on vacation, the Mendocino County Sheriff's Office said in a statement.

"Several items have been positively identified, by family members, as belonging to the Thottapilly family," it said. "These items were of a personal nature and will not be described further at this time, but it does confirm the fact the vehicle that was seen going into the river was that of the Thottapilly family."

The family from Santa Clarita in Los Angeles County was last heard from while driving along California's redwood coast, about 180 miles (290 kilometres north of San Francisco).

The family was travelling home from Portland, Oregon, and was reported missing April 8 by a relative in San Jose who had expected them to arrive for a visit two days earlier.

The family members were identified as Sandeep Thottapilly, 41; Soumya Thottapilly, 38; Siddhant Thottapilly, 12; and Saachi Thottapilly, 9.

The family was travelling as a strong storm dumped rain on Northern California.

Before the family was known to be missing, authorities in Mendocino County received reports that a vehicle southbound on U.S. 101 went off the highway and tumbled into the Eel River. The vehicle had submerged by the time rescuers arrived.

"The Mendocino County Sheriff's Office has been in contact with numerous other county dive teams and technical rescue responders that can be called upon, when the vehicle is located, to assist with recovery of the vehicle," the office said. "Once recovered the Highway Patrol will conduct a complete mechanical inspection of the vehicle as part of the accident investigation."

Farther south along the Mendocino County coast, authorities continue to look for members of a family missing since an SUV made a deadly and possibly intentional plunge off a towering ocean bluff along State Route 1 last month.

Sarah and Jennifer Hart and their six adopted children were believed to be in the family's SUV at the time. Five bodies were found March 26 near Mendocino, a few days after Washington state authorities began investigating the Harts for possible child neglect, but three of their children were not immediately recovered from the scene along the shoreline.

A body was pulled out of the surf last weekend but was not immediately identified.
