Murder and burglary charges have been filed in the killing of an "American Idol" music supervisor and her husband at their home in Los Angeles.

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.

Days after 22-year-old Raymond Boodarian's arrest in connection with the deaths of Robin Kaye and Tom Deluca, he is due for a first court appearance.
