"They've been out here since early this morning," said Rosa Rodriguez who lives only a few houses away from the mustard-colored home in the 1700 block of S. Palm Avenue which had become the focal point of the investigation Thursday. "They were out here yesterday early, too and they didn't leave until almost 4 p.m."
Ontario police officials received information about 29-year-old truck driver Oscar Escobar which led them to the home, Sgt. David McBride, spokesman for the police department said.
"Right now we're not looking for a body," said McBride as a bobcat was brought to the scene to help move pieces of broken up pavement from the back yard. "At this point, we're just meticulously searching the scene for evidence in this case."
Officers served a search warrant at the home Wednesday and interviewed several people, but McBride said no one was arrested at that time. Neighbors said they saw at least three people, two women and a man, taken from the location handcuffed.
Escobar was reported missing to the Orange County Sheriff's Department in August of last year, McBride said. After the 29-year-old truck driver made a delivery, a friend dropped Escobar off at Mango Street and Foothill Boulevard in Fontana, he said.
Two cadaver dogs, one from the Orange County Sheriff's Department and another with the Los Angeles County Coroner's office, went through the home searching for any clues that may lead officials to Escobar's whereabouts, McBride said.
The residential street, which will usually allow children to play safely in the roadway with little threat from traffic, was overtaken by police vehicles, news vans and curious residents from surrounding neighborhoods. At least four news helicopters hovered over the area to the annoyance of some residents.
"I'm about done with all of the helicopters," said Laura Bedoy who lives on the northern end of S. Palm Avenue. "They've been out since earlier today and the sound is driving me crazy."
Bedoy and others out Thursday evening watching the spectacle unfold were shocked the search for the missing man had made it's way to their neighborhood.
"I'm out late sometimes and I don't ever feel scared," Bedoy said. "It's usually really calm around here. I can't believe it."
Ontario detectives said they expect to be at the Palm Avenue address until tonight and they will most likely return Friday.
