Deputies responded on Jan. 30 to a home in Ontario, 35 miles east of Los Angeles, just after 9 p.m. when they found three dead bodies. 

The victims were identified as Sonia Ramirez, 68, her husband George Ramirez, 66, and the couple's son David Ramirez, 43. Investigators said all three victims had been shot.

Neighbors told FOX Los Angeles they saw suspicious activity at the house, including cars and people going in and out.
