The investigation into the deaths of two children, a woman and a man in a home indicates a possible murder-suicide, a police spokeswoman said Tuesday.
The children and the woman had multiple gunshot wounds and the man had a single wound to the head, spokeswoman Martha Guzman-Hurtado said.
A handgun was found and no suspect was being sought, she said.
"Everything that has been confirmed so far indicates it could be a murder-suicide but that has not been confirmed," Guzman-Hurtado said. "They are questioning other people before making that conclusion."
Police responding to the home at 8:30 p.m. Monday found the bodies of a 12-year-old girl, an approximately 10-year-old boy and the two adults between the ages of 30 and 35.
They appeared to be a family but identification by the coroner was pending.
Police were called by a 16-year-old relative who did not live there but went to the home after being unable to make contact. It was not clear how long they had been out of contact.
Jonathan Garcia, 22, lives across the street and was watching television at about 8:30 p.m. when he heard yelling.
"I hear `get down, get down!' I recognize that as a cop's voice," he said.
Garcia looked through the window and saw police in SWAT gear with submachine guns.
"So I come outside. They're all rushing at the house. There's a younger kid, probably 16 years old. He's screaming and yelling ... he's saying `that's my mom! That's my mom!"
Police handcuffed the frantic teen.
"They were still trying to figure out what happened," Garcia said.
Also outside were a man and a woman. Garcia said the woman was crying and kept screaming in Spanish `They're all dead, they're all dead. He killed them all!"
Garcia said the family had lived in the home about three years.
"They were friendly. My dad talked to him (the husband) every now and then," Garcia said.
The bodies and blood were spread throughout the house, police Sgt. Doug Imhof told KNBC-TV and KABC-TV.
Guzman-Hurtado said records show the last time police visited the home was in June 2010 for an unspecified code-enforcement matter.
"It's a sad day in Fontana," Guzman-Hurtado said. "This is one of those days where we're all supposed to be celebrating with family, making new memories with family as we say goodbye to 2013 and welcome the New Year. It's not a day to be mourning lives lost."
Fontana is a city of about 200,000 people in San Bernardino County about 50 miles east of downtown Los Angeles.
