The FBI joined Tulare County Sheriff's Deputies and other law enforcement officers in searching the home on "Bee" Street near Walnut in Exeter.
Tulare County investigators served a search warrant at the house after getting a disturbing report. They tore out a lemon tree in the backyard and left piles of dirt where they dug.
The FBI worked with specialized dogs from the Santa Clara County Sheriff's Office. Hayward Police also came looking for possible connections to crimes there.
For now, Tulare County investigators are sorting through the evidence and planning to refer the case to the district attorney's office.
