Northampton County authorities are looking for additional victims of a 20-year old man who has already admitted to two rapes.
David Martinez met the girls on Facebook and then took them to his home in the 700 block of Maple Street in Bethlehem and raped them, police said. One of the girls was 14-years-old; the other is 17.
Police and District Attorney John Morganelli said they believe Martinez, 20, may have done this to other girls. He told police, "There may be other victims out there."
Martinez also told police he is a sex addict and could not control himself; when he was in the presence of a woman, he felt compelled to have sex with her.
The sexual assault of the 14-year-old took place in February of 2012 and the rape of the 17-year-old took place last September.
Martinez may be preying on young girls 18 and under, Morganelli said.
Martinez is being held in the Northampton County Prison.
Bethlehem officials are looking for any other possible victims. Anyone with information is asked to contact Detective Moses Miller at 610-997-7674 or the Northampton County district attorney's office at 610-559-3020.
