Tom Bennett said."The concern for foul play was increased due to an accumulation of mail (and) newspapers, and pets not being fed," Bennett said. "Based on the circumstances, the deputies decided to force entry to the home."Due to an array of household security equipment, including reinforced doors and grills over the windows, the deputies needed firefighters' help to get inside.The bodies of who authorities believe were Ochoa-Fernandez and her sons, Jose Jr., 10, and Angel, 3, showed no obvious trauma, Bennett said.The boys' father Jose Fernandez, was kidnapped in front of them in Tijuana, but the family was unable to meet ransom demands, neighbors told the newspaper.Susana Jimenez, the next-door neighbor, said she still can't believe what detectives found inside the house."I'm very shocked -- very saddened," Jimenez said."It really freaks me out. I don't know how to put it in words. It's gone to the heart, really," neighbor Brenda Jackson said.
