At the request of police, the coroner has indefinitely delayed releasing the names of four people found shot dead Sunday in Northridge.

Assistant Chief Coroner Ed Winter said this morning there is a "security hold" on the names at the request of Los Angeles police.

Ordinarily, the coroner releases the names of homicide victims after their next of kin is notified. But Winter said it's not unusual for police to ask for a delay.

"It could be a few days, or they could go as far as asking for 90 days or more," Winter said.

Detectives from the LAPD's Robbery Homicide Division were not available for comment this morning. They had made no arrests in the case at last report, but said they did not believe the killings were random.

Police were called to a home in the 17400 block of Devonshire Street at 4:25 a.m. Sunday.

The bodies of two men and two women were found close together in a yard beside the five-bedroom house. Three were face down, and one man was face up.

City Councilman Mitchell Englander said the house was filthy, with mattresses scattered on floors and one bedroom door blocked by debris, meaning occupants must have had to enter and exit through a window.

More than a dozen people apparently lived in the house, which smelled of feces and urine, Englander said. He called it an illegal boarding house, something the city has been debating legislation to block.

The owner of the home, Yag Dutt Kapil, told the Daily News yesterday the home was not a boarding house. But he said he rented out rooms to others.
