SAN JOSE(TIP): Four Indian Americans; Sandeep Thottapilly (42), his wife, Soumya (38), and their two children Siddhant (12) and Saachi (9) have been missing since April 5. They left for a road trip from Portland, Oregon, to San Jose, California, last month, but haven’t been seen or heard from in several days.

The family was supposed to visit their relative in San Jose on April 6 before returning to their home in Valencia.

The investigators are trying to locate the family by tracking their mobile phones. They have started the procedures to obtain search warrants for cellphone carriers. They are also checking to see whether the car the family was driving was equipped with a locating system.

A flier posted online by friends of the family says the Thottapillys were in a maroon Honda Pilot with a California plate (7MMX138).

The San Jose authorities, who are investigating the case, are checking if the car was swept away into the Eel River as a result of a massive storm in Northern California. An SUV matching the description of the family’s car was reportedly swept away into the river in Mendocino County on April 6. But, the car has not been recovered due to tough weather conditions.

The Santa Clarita Valley Sheriff’s Station is also on the lookout for the family.

While the authorities continue their search for the family of four Indian Americans who have gone missing, friends and relatives of the family are pleading for assistance of the community to locate them.

Meanwhile, India’s External Affairs Minister Sushma Swaraj informed the family members that she was “in constant touch” with the Consulate in San Francisco.

“They are coordinating with the police. Rest assured. We will spare no effort,” Swaraj tweeted.

Babu Subramaniam Thottapilly, the father of Sandeep Thottapilly, had tweeted seeking the help of Swaraj to locate his son and family. He has also requested Union Bank authorities to extend their help to “ensure that law authorities are able to track” Sandeep and his family.

Sandeep Thottapilly, who is from Surat, in the Gujarat state of India, is a vice president at Union Bank and the family lives in Los Angeles.
