A former KBR firefighter maintained Thursday that he had consensual sex with a Houston-area woman who says she was drugged and raped while working for the defense contractor in Iraq.

Jamie Leigh Jones, 26, sued KBR in federal court in May 2007, saying she was raped by several Kellogg Brown & Root firefighters while stationed at KBR's Camp Hope installation in Baghdad in 2005.

Jones also is accusing the Houston-based firm of creating a "sexually hostile working environment" by neglecting to enforce their sexual harassment policies, according to court documents.

Charles Boartz, 34, the only alleged assailant identified in the suit, told jurors Thursday that he and Jones shared a drink at a party with several KBR employees before she invited him back to her barracks. He said the two had intercourse in her room and in the barrack's stairwell and that the only time Jones asked him to stop was when she became concerned that he was seeing another woman.

"I told her I was fine, and we continued," Boartz said.

Boartz also said that because he has been a firefighter since he was 17 and was trained as a first responder, he knows how to determine when someone is in shock.

Jones, he said, did not display symptoms of shock the next morning when they woke up.

He said the only time she was "a little bit off" was when she re-entered the room after visiting the bathroom and asked Boartz if they had unprotected sex.

"I said, 'Yes, are you joking me?' and then she said, 'No, I'm just kidding,' " Boartz said.

Jones has insisted throughout the trial that she has no memory of the alleged rape because her attackers spiked her drink with what she believes was a date rape drug called Rohypnol.

Boartz's attorney Andrew McKinney said Tuesday that a urine test given to Jones by an Army doctor after the alleged assault found no evidence of date rape drugs in her system.

Jones' attorney, Ron Estefan, said Thursday that Boartz, who said he was interviewed by State Department officials two days after the alleged attack, was not questioned as aggressively by KBR as Jones.

Boartz also said he was not disciplined by the company for the alleged rape.

Boartz said he quit KBR in May 2006, 10 months after Jones' allegations surfaced.

Jones told jurors during her testimony Monday that after being examined by an army doctor, KBR representatives and armed guards held her against her will in a shipping container for nearly six hours and denied her food, water and the opportunity to call home for help.

"Every minute I was in that trailer felt like forever," Jones said.

The trial will continue Friday in U.S. District Judge Keith Ellison's court.
