'American Idol' music supervisor and husband killed with their own gun: DA

The gun allegedly used in the killing of an "American Idol" music supervisor and her husband at their home in Los Angeles belonged to the victims, according to prosecutors.

Robin Kaye and her husband, Thomas Deluca, both 70, were found shot to death in their Los Angeles home during a welfare check on July 14, authorities said. Kaye had been with "American Idol" since 2009, according to a spokesperson for the ABC television show.

Responding officers found the victims dead with multiple gunshot wounds, including to the head, police said.

It is believed the couple was killed four days earlier, when the Los Angeles Police Department said it received a 911 call about a possible burglary at the Encino address.

The suspect -- 22-year-old Raymond Boodarian -- is accused of scaling a fence onto the property that day, entering the home through an unlocked door and then shooting and killing the couple when they arrived home from the grocery store about 30 minutes later, authorities said.

A firearm recovered from the suspect's Encino residence came from the victim's home, according to Los Angeles County District Attorney Nathan Hochman.

"It was a gun that he had recovered from the actual house. It was Robin and Tom's gun," Hochman said during a public safety forum in Encino on Monday. "It wasn't his gun. Which is exceptionally tragic."

Boodarian was arrested on July 15 and has since been charged with two counts of murder and a count of residential burglary, with the special circumstance allegation of multiple murders and murder during the commission of a burglary, the district attorney's office said. He has not yet entered a plea to the charges. He is being held without bail and his next court hearing is Aug. 20.

Hochman said officers were led to Boodarian after the suspect called police.

"Mr. Boodarian got caught because he used his cellphone to contact police concerning this situation," Hochman said during Monday's meeting. "Police were able to ping the cellphone, find out where he lived, go to his residence and arrest him."

Police had previously said they received two 911 calls regarding the residence on July 10. In an update on Tuesday, the LAPD said that one call was from a neighbor reporting a potential burglary in progress, and the second, subsequent call was "from an individual claiming to be a resident inside the location."

"The caller eventually advised that police response was not necessary and follow-up attempts to reach the caller were unsuccessful," police said.

The first caller was also unable to be reached during attempts to follow up, police said.

Responding officers were unable to make entry into the home, which was "secured with surrounding walls," and an aerial check from a helicopter saw no signs of a break-in, the LAPD said. After making additional attempts to reach the 911 callers and residents at the location, officers cleared the scene, police said.

LAPD Deputy Chief Marla Ciuffetelli told attendees of the packed forum that police are continuing to assess the initial July 10 response to the couple's home, which she said was "quite fortified."

"We're always striving to try to respond better," Ciuffetelli said. "We're taking a very close look at the response. I'm not saying that there was any mistakes made, but we're making sure that in similar circumstances, that we respond appropriately."

In the wake of the killings, LAPD Capt. Michael Bland said the department was upping patrols overnight in Encino.

"This is not something we take lightly," he told the crowd.
