RICHMOND, Virginia - By all appearances, the man arrested in connection with the disappearance of a British-born University of Virginia student has led a fairly ordinary life: He worked at a hospital, helped coach youth football for a time and attended a Christian university.

Now, however, 32-year-old Jesse Leroy Matthew Jr. is a central figure in a case that has roiled the college town of Charlottesville. Police have charged him with abduction with intent to defile Hannah Graham, an 18-year-old sophomore who went missing on Sept. 13.

Charlottesville Police Police Chief Timothy Longo told a news conference on Wednesday night that Matthew had been captured and was in custody in Galveston, Texas. He said authorities did not know why Matthew was in Texas. He said they are now working on getting him extradited to Virginia.

Longo added that police were still searching for Graham.

"This case is nowhere near over," Longo said. "We have a person in custody but there's a long road ahead of us."

Matthew was captured at a beach in the community of Gilchrist about 3:30 p.m. after police received a call reporting a suspicious person, the Galveston County Daily News reported. The newspaper quoted Galveston County Sheriff Henry Trochesset as saying that a deputy responding to the call found a man who had pitched a tent on the beach with his car parked nearby. Trochesset said a check of the car's plates revealed it was the vehicle sought in connection to the case. Authorities were trying to get a warrant to search the car, he added.

Police believe Matthew was the last person seen with Graham, and obtained a felony warrant for his arrest late Tuesday. Matthew had sped away from a police station Saturday after coming with family members to ask for a lawyer. It's not clear whether the longtime area resident knew Graham, who was last seen in an area lined with shops and restaurants where police believe she went into a bar with him.

The case has spread fear through the quiet community about 70 miles (112 kilometers) west of Richmond. Authorities have increased patrols and a late-night transportation program for students, who also have begun walking in pairs at night and are paying closer attention to their surroundings.

According to police, Graham met friends at a restaurant for dinner on Sept. 12 before stopping by two parties at off-campus housing units. She left the second party alone, police have said, and sent a text message to a friend saying she was lost.

Surveillance videos showed her walking, and at some points running, past a pub and a service station and then onto the Downtown Mall, a seven-block pedestrian strip where police believe she entered a bar with Matthew.

The university said he's been employed at the University of Virginia Medical Center since Aug. 12, 2012, as a patient technician in the operating room.

The charges against Matthew surprised Dave Hansen, who first met him about 11 years ago when Hansen served as an assistant pastor at an area church.

"I always thought he was a gentle giant, just a nice guy," Hansen said. "He seemed genuine with his faith and spirituality. ... I don't see him doing this at all, but that's usually the case, I guess."

Hansen said he's only kept up with Matthew through Facebook, but ran into him at the university's medical center within the last year. He said the soft-spoken Matthew greeted him in an elevator with a high-five.

Matthew attended Liberty University from 2000 to 2002, said officials with the Lynchburg school founded by the late Rev. Jerry Falwell. The school's athletics website listed him as a defensive lineman on the football team.

More recently he also served as a part-time volunteer for the football team at The Covenant School, a private Christian pre-kindergarten through 12th-grade school in Charlottesville. Officials said his involvement with the school began last month following interviews with the athletic director and head football coach, as well as normal background and reference checks.

After Matthew was named a person of interest in Graham's disappearance, school officials said in a letter that he will "no longer be working with our football program while this matter is being clarified and resolved."

While Matthew has had past brushes with the law, the details of those cases are not clear.

The latest revelations came late Tuesday, when police, who have searched Matthew's car once and his apartment twice, decided they had probable cause to charge him in the disappearance. Longo declined to say what new information police had, but authorities sent several items, including clothing, to a state forensics lab for testing.
