Investigators said at the time of Raymond Boodarian's arrest that they were working to determine if he had any connection to Kaye and Deluca, and if he was involved in any past calls for service at the couple's residence.

Charges have been filed against the man suspected of killing an "American Idol" music supervisor and her husband in their Los Angeles home.

In December, a judge dismissed the cases against 22-year-old Raymond Boodarian after a mental health evaluation was completed, and the court records indicated he was placed in a conservatorship, which puts another adult in charge of major decisions in a person's life if they've been diagnosed with a severe mental disorder.

Robin Kaye and her husband, Thomas Deluca, both 70, were allegedly killed following a suspected burglary at their home last week.
