The tragic discovery comes after investigators found personal items belonging to the Thottapilly in the Eel River.
Authorities said they found "various personal items consistent with a family traveling on vacation" during the course of the two-day search. Relatives of the Thottapilly family positively identified the items as belongings of their family members, authorities said.
The family was scheduled to arrive to visit a friend in the San Jose area on April 6, but never showed up, authorities said. Sandeep, 42, Soumya, 38, Siddhant, 12, and Saachi, 9, were last seen in Klamath, in Del Norte County on April 5. They were reported missing on April 8.
A witness recalled seeing an SUV matching the description of a missing Valencia family's vehicle plunge into the Eel River in Northern California.
