ross apparently spotted the two girls hitchhiking along the border of rhode island and connecticut. >> i picked them up. they wanted me to drop them off at a gas station. i drove right by the gas station. one of them pulled a knife on me, like a kitchen knife type thing. and i almost drove off the road, i was so surprised. and i don't know what i said, but i said something and she gave the knife to me. obviously scared her. anyway, took them to a place, tied them up with some cloth that i had in the back seat. >> and he admitted that while he was sexually assaulting the first one, they were talking to each other. and all he said was that they were -- one was telling the other to cooperate and hopefully he'll let us go. >> i put the younger girl leslie shelley into the trunk of the car, and i took the other girl, april brunais out and i raped her and killed her and i put her in the front seat. >> then he went to the car and he took out leslie shelley who was 14 years old i believe at the time. a very tiny girl. and he said to me that he was already in so far he didn't know what to do.
