The California Highway Patrol reported April 6 that a witness had seen a vehicle go over the side of a steep embankment on US-101, south of Dora Creek in Northern Mendocino County. Sandeep Thottapilly (41), Soumya Thottapilly (38), Siddhant Thottapilly (12) and Saachi Thottapilly (9) went missing after the auto in which the family was travelling fell into the river on April 6.

The body of Siddhant Thottapilly was found at about 4 p.m. submerged in the Eel River about 6 miles (9.6 kilometers) downstream from where the family auto reportedly crashed, Mendocino County Sheriff's Office Capt. Gregory L. Van Patten said in a statement. "An autopsy is expected to be performed this week as part of the Coroners investigation into the incident", it added.

The other, vehicle T therapy, genetically reprograms a patient's immune T-cells to find and destroy cancer. Their tumors lacked certain mutations that would have made them eligible for other, "targeted" treatments.
The body was found a day after the auto with Siddhant's father and younger sister inside were pulled from the river sediment. They'd been traveling south from OR along Highway 101 when the incident occurred, officials said.
Officials last week determined the vehicle belonged to the Thottapilly family.
The search team on board a boat had smelt gas below them Sunday, April 15. "Visibility was extremely poor and divers noted the vehicle was encased in a large amount of sediment from the river current", the statement said. That evening, at approximately 6:30 p.m., rescuers were able to partially remove the Honda Pilot from the river by using a tow truck.
Five bodies were found March 26 near Mendocino, a few days after Washington state authorities began investigating the Harts for possible child neglect.
