According to police, during an interview with Sanchez, she admitted her role in the murders and said she and Maldonado went to the apartment looking for money and that they didn't think anyone was home when they entered through a back window.

Once inside, Sanchez said they were confronted by the residents and that Maldonado shot them. They then took a box from a closet that they thought contained money and left the apartment through the front door. The box, according to the affidavit, was empty.

Sanchez, according to the document, is the ex-girlfriend of one of the victims and was involved in a contentious custody dispute over their son. It's not immediately clear if their son is the same child present and unharmed during the shooting and robbery.

The investigation into the quadruple homicide is ongoing, police said.
