AURORA, Ore. -- An Aurora man faced a judge in court Tuesday for allegedly raping a 13-year-old girl he met on MySpace.

Scott Knight, 28, of Aurora was arrested and booked into the Marion County Jail on Sunday.

Outside the courtroom Tuesday, Knight’s mother told KGW that her son didn’t know the girl was only 13 and that she had identified herself as an 18-year-old. However police said it was very clear she was not 18.

“That’s not Scott, Scott may do things, but this is not Scott. He met this girl on a Web site, it happened to be a Web site that only 18-year-olds can go on, He doesn't understand and I don't understand. He doesn’t do that,” said Knight’s mother, Janice Abraham.

"She set him up and it's not right. She should be under house arrest or something, she should be stopped," added Knight's sister, Angelica White.

Police said they learned about the abuse after someone living with the girl noticed she was using their cell phone to send text messages to Knight after the two met on the popular Web site MySpace. That sparked a six-month police investigation.

Police said Knight chatted with the girl a few times online and then the two met, which was when the alleged abuse occurred.

He faces several charges, including sex abuse, kidnapping, rape and sodomy, all in connection with the abuse of a child. Police said they were also investigating a possible second suspect in the case.

Knight lives in the 13500 block of Wisteria Court NE in Aurora. He was also facing a felony theft warrant out of Multnomah County on unrelated charges.
