Los Angeles Police Department officials said an arrest was made Tuesday in the killings of "American Idol" executive Robin Kaye and her husband, Thomas Deluca, who were found dead Monday in their Encino home.

Producers of the singing competition show “American Idol” are mourning the loss of one of their own.

Robin worked as the music supervisor on 'Idol' for at least 15 seasons, according to her IMDB page, and she won multiple Guild of Music Supervisors Awards for her work on the show.
