DALLAS — According to a criminal complaint, Chad Cameron Camp, 26, is accused of sexually contacting a 13-year-old girl as she flew from Dallas/Forth Worth International Airport to Portland last week.

As she sat in a window seat on her way back home to Portland, federal authorities say the teen was subjected to the sexual advances of 26-year-old Chad Cameron Camp. Authorities say Camp was sitting next to the girl in the middle seat on the American Airlines from D/FW Airport.

"She’s devastated," says the girl's attorney, Brent Goodfellow. "She’s hurt. She's sad. She's angry."

He says the girl was flying as an unaccompanied minor on the flight, which costs an extra $150.

Goodfellow spoke to reporters in Oregon Monday after Camp's appearance in federal court, where cameras aren't allowed.

"Their child’s life has changed forever," he says of the victim's family. "I don't know that justice will come in this lifetime for them."

According to the criminal complaint, Camp sat next to the girl despite there being open seats on the plane. The victim said Camp was mumbling and cursing, and began to brush up against her. The complaint says the victim felt "frightened" and "trapped" while Camp placed his hand on her upper thigh.

Eventually, the complaint says, a flight attendant saw Camp's hand in the girl's crotch area and a single tear ran down the girl's cheek. The attendant moved Camp and alerted authorities.

The complaint says another passenger on the flight told authorities they had seen Camp have four drinks at a bar at the airport before boarding the flight from D/FW to Portland.

For its part, American Airlines issued this statement:

"American cares deeply about our young passengers and is committed to providing a safe and pleasant travel experience for them. We take these matters very seriously and have cooperated fully and immediately with law enforcement officials in their investigation of the suspect. Due to the pending criminal case against the suspect, we are referring all questions to law enforcement."

Goodfellow says the whole thing is absurd and demands changes to keep kids safe on the airline.

"That they're not molested, that they're not harmed, that they're not injured when we allow others to take our children and be responsible for them," he says.

Camp, who has no criminal history of sexual offenses, will remain in custody. His next court appearance is July 15, according to our sister station KGW in Portland.
