Vacaville detectives said that with the use of phone records and analytics software, they were able to start a grid search on September 2 near Lake Berryessa, where the burned remains were located and found on September 10 to be Castro’s body.

The Solano County Coroner’s Office ruled the death a homicide but the exact cause of death is still unknown, police said.

Authorities said Serriteno was located in the city of Santa Clare Friday morning through several interviews, cell phone records, city camera footage and other evidence.
