Police responded to the girl's home in the 4000 block of Rio Vista Avenue and she told investigators he had forced his way through the front door of her home as she went inside. She fought him off and he fled before police arrived.The girl then locked the door after he left, hid in a closet and texted her father: "DADDY COME HOME NOW. SOME GUY TRIED TO RAPE ME."He is described as a white man about 30 years old with a medium height, a thin build and a beard. When he followed the teen girl home from school, he was wearing a black beanie, a blue long-sleeved button-down shirt, light-colored cargo shorts and a dark messenger bag.
