DOWNEY, Calif. -
Four people were detained Thursday in connection with a shooting spree that killed three people and left two others injured at a Downey fire-prevention business and the nearby home of either the business owner or relatives.
None of the people detained by Downey police was immediately arrested in connection with the shootings, which police called a targeted attack against the family that owned the business where the initial shots were fired and the nearby home where more gunfire erupted.
Details of the arrests were not immediately released. Various media outlets reported that three of the detainees were men, and one was a woman.
The gunfire erupted around 11:10 a.m. Wednesday at United States Fire Protection in the 8700 block of Cleta Street, and a short time later at a home two blocks away, according to police.
Two people died at the business -- one male and one female -- while another female victim was killed at the home. Two other people were wounded and were listed in critical but stable condition. One of the wounded was a 13-year-old boy.
Downey police Lt. Dean Milligan said the victims were all members of the same family, leading police to conclude that the family was being specifically targeted.
"We do not believe that this was a random act of violence," Milligan said Wednesday. "We do believe that for some reason this family was targeted both at their place of business and their residence. We do not know why at this point in time. But that being the case, two specific locations this close to each other all involving family members, we do not believe this act was random. There is a direct correlation for some reason."
Officials said the gunman first went into the business, spoke with some people inside and then opened fire, then went down the street to the home, which police said was a residence of either the business owner or relatives.
Police said they received two 911 calls about the shootings, one at 11:12 a.m. telling them shots were fired at the business, and then five minutes later reporting shots fired at the nearby residence in the 8500 block of Cleta Street.
After the shooting at the home, the suspect drove away in a 2010 black Chevrolet Camaro with California license plate 6LEA010, police said. The car is owned by one of the victims or a relative of a victim, Milligan said.
The motive for the shootings remained a mystery. Milligan said none of the victims could identify the suspect.
Milligan declined to speculate on what might prompt someone to target the family. He said there was no immediate evidence that anything was stolen from either the business or home.
Unconfirmed reports circulated today that the shooting may have been related to a Craigslist ad offering the Camaro for sale. Meanwhile, an unnamed Downey City Council member told the Los Angeles Times he believed the shooting was a drug hit.
Earlier Thursday, police said investigators were reviewing surveillance video from businesses in the area in hopes of identifying a suspect.
