Perez and his roommates Dorothy Grace Maraglino and Jessica Lynn Lopez have all pleaded not guilty to murder charges and are being held on $3 million bail each.

Perez told deputies he and Killgore went to downtown San Diego and he lost her at a club called Whiskey Girl. However, cell phone records for Perez and Killgore indicated they were in Fallbrook at the time, according to the search warrants.

Maraglino, 37, told deputies that she was a dominatrix, according to the search warrants. Lopez, 25, was interested in sadomasochism and had a collection of sex toys, according to the affidavits.

Prosecutors, deputies and Killgore's family have stressed that Killgore was not a willing participant in the sex games at the Fallbrook home.
