Noel Betrand, Accused Of Sexually Assaulting A Woman At DIA, Will Stand Trial

DENVER — A Denver judge has ordered a man accused of sexually assaulting a woman at Denver International Airport to stand trial.

Twenty-six-year-old Noel Bertrand of Portland, Ore., is charged with sexual assault and kidnapping.

Bertrand's defense attorney said Thursday the sex was consensual.

Authorities say Bertrand promised during the attack to teach her about pleasure and pain and to make her his sex slave, according to the Denver Post.

Bertrand was accused of assaulting a 22-year-old woman just after midnight April 12 after she missed a flight. Authorities say they struck up a conversation at an airport restaurant before he attacked her at nearby gate. They say airline employees saw the assault through a window and intervened.

In June, Mark Adams and Kris Musil, aircraft mechanics, witnessed the April incident from the jetway through a window and ran to help the woman. Police say Adams and Musil detained the suspect until security could arrive and helped the victim go through her luggage as she looked for an inhaler to calm her shallow, rapid breathing, The Huffington Post/AP reported.

Adams said the suspect tried to play off the incident by pretending he knew the woman and telling them they "don't know the difference between rough sex and fighting."
