Margarito Andres, a 22-year-old from Boynton Beach, is being sought by police after his 13-year-old stepsister reported Andres had been sexually assaulting her since she was 10 years old. In the probable cause affidavit, the victim told police that she'd been left home alone with Andres on Thursday and that he had told her to take off her pants.

Boynton Beach Police officers found evidence that the girl had been anally pentrated. In a taped interview, she told them that there had been at least 40 similar instances since she was 10 years old and that when she was 12 Andres told her he would kill her if she reported him to police.
