Murder-Suicide Ruled Out in Ontario Triple Slaying

Investigators by late Monday had ruled out murder-suicide as the possible cause of death for a man discovered in the driveway of an Ontario home and two others found inside the residence.

Police responded to the home in the 1000 block of South Magnolia Avenue at 6:15 a.m. Monday. The man found in the driveway had suffered a gunshot wound, police said.

"As officers entered the rear house, they discovered two more deceased males lying on the floor of the residence. It is unknown at this time what injuries the two males suffered," Sgt. David McBride said in a statement released Monday afternoon.

Later in the day, police said the two men found inside the home also appeared to have been shot, adding that the coroner will determine the official cause of death. Police have not released the identities of the victims but did say two of them were African-American, while the third was Latino.

Investigators found "equipment for the cultivation of marijuana, several pounds of marijuana and several weapons," said Sgt David McBride, with Ontario Police.

Police said it's still too early to connect that evidence to the killings and are asking for the public's help to find those involved in the slayings.

"There must have been someone in the neighborhood who saw something unusual. We want to gather that info and work on finding a suspect," McBride said.

The slayings brought Ontario's number of murders for all of 2012 from two to five overnight, police said.

Andrew Jaquez said he thought he heard fireworks.

"It wasn't that loud. Didn't think it was gunshots until the morning ... when police were all over the place," he said.

But neighbor Dave Bylsma feared the worst.

"There was first one shot, then thirty seconds later two shots," he recalled. "Then another thirty seconds or so, three shots."

Anyone with information was asked to call the Ontario Police Department at 909-395-2764.
