A teenage girl was tied up and raped at gunpoint during a home invasion robbery in West Philadelphia Wednesday, while her grandmother looked on helplessly. A neighbor said that she found the women tied up in their home about 10 a.m. when she became concerned after they did not answer her phone. Their phone line had been cut and the 13-year-old girl had been raped. "A black male entered the residence, with his identity concealed, through an open door," said Michael McCerric of the Philadelphia police. The women were taken to the hospital, and the grandmother returned to the house to help with the investigation. "(I) put the phone down, looked up and there he was standing there with a gun on us," said the grandmother, who did not want to be identified. Detectives from the Special Victims Unit said that the suspect was wearing a scarf on his head and on his face, when he entered the house. Police said that the man tied the girl and her grandmother, robbed them and then raped the girl. "I kept trying to tell her not to cry, because I figured the more she cried, the more she was going to make him mad and the more he was going to do and she finally stopped crying. You could tell she was very, very upset. She almost went catatonic, if you know what I mean," the grandmother said. The woman said that the torment lasted about an hour. She said that she was afraid he would kill both of them. "When he finally walked out the door, I was trying to loosen my hands, and (my granddaughter) kept begging me not to because he had told us not to dare try to loosen our hands," the grandmother said. A neighbor found them minutes later and called 911. But the suspect was gone. Other neighbors wondered if the attack was connected with some trouble at the house over the weekend. Rosetta Wright said that a gang of teens has been terrorizing the neighborhood. She said that she was attacked last September in her front yard. Police are investigating whether the girl or her grandmother might have known the rapist. They removed several bags of evidence from the scene, questioned neighbors and reassured the grandmother, who was still shaken from the attack. Authorities are looking for a black male in his 20s, wearing a black and white striped shirt, baggy light blue jeans, and Timberland boots. The suspect was wearing a yellow scarf on his head and a blue scarf covering his face, according to the police report.
