A family of four has disappeared while on a West Coast road trip from Southern California to Oregon.
The Thottapilly family left Valencia, Calif., on March 30, driving more than 900 miles to Portland and stopping at several destinations along the way.
But they never made a scheduled stop on the way back in San Jose and the family's contact there didn't hear from them as planned.
According to a missing persons flyer posted to social media, all contact with the family was lost April 5 after they were last seen in the Klamath - Redwood National Park area.
The flyer ID'd the family as husband and wife, Sandeep and Soumya Thottapilly, and their 12-year-old son Siddhant and 9-year-old daughter Saachi.
The California Highway Patrol responded Friday to reports of a vehicle falling off the side of a steep embankment on the 101 Freeway in Mendocino County, according to the LA Times.
The description of the vehicle, a Honda Pilot, matches that of the SUV the Thottapilly family was driving when they vanished.
Authorities now fear their vehicle went into a rain-swollen river in Mendocino County.
Search teams from multiple agencies were unable to search the river over the weekend because it was deemed unsafe for divers.
In a Twitter post, a user who identified himself as Sandeep Thottapilly's father in India pleaded with his country's minister of external affairs to work with California authorities to help find his son.
"I am a senior citizen and resident of Surat, Gujarat. My son Sandeep Thottapilly is residing in California, USA. He and his family are reported missing since last Thursday. Would request your good office to take up this matter with concerned authorities in USA and help find my son and his family as soon as possible," the post read.
