A Bay Area woman using an phone tracking service to search for her missing husband made a sad and gruesome discovery over the weekend, when the app led her to the site of his body.

49-year-old Pacifica resident Jayesh Patel didn't come home as expected Friday night, California Highway Patrol spokesperson Officer Art Montiel tells the Chron. His wife, who was not identified by name in media reports on the incident, reported him missing that day, and launched her own investigation Saturday morning.

Using a cell phone tracking app, she determined that Patel's phone was near a San Mateo freeway. Traveling to that location, she "discovered his body in the crumpled wreckage of his car below an elevated ramp at the interchange of Highway 101 and state Highway 92," CBS 5 reports.

She remained at the scene and called the police, the Chron reports. When responders arrived at around noon Saturday, the wreck was severe enough that they had to use "the 'jaws of life' to tear off the doors" and pull out Patel's remains.

According to CBS 5, Patel has been headed east on the 92 connector to 101 when his "2000 Mercedes-Benz struck a concrete barrier and then ended up being launched over it, falling into a patch of open field under the highway interchange" then "came to rest behind a fence and some bushes that apparently blocked it from the view of drivers in the area."

It's still unclear why Patel crashed, police say, estimating that the wreck occurred between 10 p.m. Friday and early Saturday morning. Anyone with information on the collision is urged to call CHP Officer K. Steinkraus at (650) 369-6261 to assist in the investigation.
