Seung-Hui Cho hired an escort to dance for him in a motel room one month before the massacre at Virginia Tech's campus, dancer Chastity Frye said in an on camera interview with a TV station in Roanoke, Va.
"He was so quiet. I really couldn't get much from him. He was so distant. He really didn't like to talk a lot," Frye said in the interview. "It seemed like he wasn't all there."
Frye said that a "creepy" Cho called the escort service she works for and hired her to meet him for one hour at a Roanoke motel, about a 30-minute drive from Virginia Tech's Blacksburg campus.
About 15 minutes into the performance for Cho, Frye said, it appeared that her client had no interest.
"I danced for a little while and I thought we were done because he got up and went to the restroom and began washing," said Frye, a white woman with blond hair.
Frye told WSLS that she told Cho she was going to leave, to which he responded that he had paid for a full hour and she had only performed 15 minutes.
When she resumed dancing, Frye said that Cho touched her and tried "to get on" her before she pushed him away. Cho then apparently respected her wishes.
Frye said she thought Cho looked familiar when she saw his face in the coverage of the Virginia Tech killings.
She got a call from the FBI, which she said tracked her down through Cho's credit card receipts. Frye said that during a weekend interview, investigators asked her to describe Cho using three words. She chose "dorky," "timid" and a "little pushy."
An FBI spokeswoman from the Richmond, Va., field office, which is overseeing the Virginia Tech case, said the FBI would not comment on possible witnesses.
"I'm not able to comment on who we are and are not talking to," spokeswoman Dee Rybiski told ABC News. "I will confirm that I have had agents there since Monday of last week -- conducting all sorts of interviews."
