NEW: Jesse Matthew arrives in Virginia and is booked into jail

Vacationer says he spoke with Matthew before arrest; "he seemed real nice"

Matthew was never charged in 2002 case due to lack of evidence

University of Virginia student Hannah Graham was last seen on September 13

(CNN) —  

Jesse Matthew, a suspect in the disappearance of University of Virginia student Hannah Graham, was questioned in connection with an alleged sexual assault nearly 12 years ago, authorities said Thursday.

Matthew had been taken into custody this week in Texas, 1,300 miles away from the town where Graham disappeared.

Matthew agreed not to fight extradition from Texas, and arrived by plane in Charlottesville, Virginia, home of the university. Officials at the Albemarle Charlottesville Regional Jail said Matthew was being processed on Friday night.

He has also been questioned in connection with an alleged sexual assault nearly 12 years ago, authorities said Thursday.

However, no charges were filed because the woman didn’t want to go forward with the case and investigators determined there wasn’t enough evidence to arrest Matthew, said Michael Doucette, the commonwealth’s attorney for Lynchburg, Virginia.

According to a statement from Lynchburg police, a woman reported she was raped on the campus of Liberty University on October 17, 2002.

Matthew told authorities that the woman consented, Doucette said, adding that there were no witnesses.

On Thursday, Matthew was sitting in a Texas jail cell, waiting for Virginia authorities to pick him up and take him back to Charlottesville, where he has been sought in the Graham case on suspicion of abduction with the intent to defile.

Jesse Matthew’s father spoke publicly for the first time Thursday since Graham disappeared about two weeks ago. He said his son would not have harmed Graham.

“For a big man, he’s as gentle as they come,” Jesse Matthew Sr. told CNN affiliate WTVR. “The only thing I could see, him, maybe trying to give the girl a ride or help her out.

“To kill or hurt somebody, that’s not my son.”

Found camping on the beach

Authorities found Matthew on a Galveston County beach some 1,300 miles from where he’s wanted in the disappearance.

Matthew did not resist arrest, Galveston County Sheriff Henry Trochesset told reporters Thursday. The sheriff added that investigators from Virginia were examining a car and a tent found at Matthew’s campsite and hoped to speak to Matthew later.

Mike Rodenberg, a vacationer who was fishing near the campsite when Matthew was arrested, said the big man came up to him to ask about why he was throwing some of his catch back.

“He seemed real nice. He was real soft spoken,” Rodenberg said. “(He) said he was down here from New Jersey and was looking for a job. I told him if I caught another red fish he could have it.”

Matthew told him that his name was George, Rodenberg said. Nothing really seemed out of the ordinary until the police showed up after a female caller reported a suspicious person.

Lawyer: No comment at this point

His comments came a day after authorities obtained an arrest warrant for his client, who police believe was the last person with Graham.

Matthew willingly went to a police station over the weekend, when there was no warrant for his arrest, Longo said. He asked for a lawyer. They spoke and then left, the police chief said.

Authorities are now offering a $100,000 reward for information leading to the safe return of Graham, 18, a second-year student at the University of Virginia.

The Northern Virginia native is 5 feet 11 inches tall with a slender build and has light brown hair, blue eyes and freckles. She was last seen September 13 wearing a black crop top and capri pants. She had an iPhone in a pink case.

They have received 1,500 tips so far in the case and are urging anyone with information to call the police tip line at 434-295-3851.
