The man known worldwide as the "bin Laden hunter" has been arrested on investigation of domestic violence after a one-vehicle crash on a Colorado mountain road, authorities said Wednesday. State Troopers found an injured woman driver and Gary Brooks Faulkner in a blue Ford Explorer that ran off North Spring Gulch Road into a ditch about 4 p.m. Tuesday in Clear Creek County, said Colorado State Patrol spokeswoman Trooper Heather Cobler. The driver, Jennifer Logie-Oliver, 51, had four fresh bruises on her head and initially told a trooper she struck her head on the dash during the crash, according to Faulkner's arrest affidavit, obtained by the TheDenverChannel.com. "Faulkner explained that he was upset with Ms. Logie-Oliver about the way she was driving down the hill and was in a heated argument with her" when the accident happened, the affidavit said. Then the woman started to cry and changed her story, saying she got the bruises "when I fell down the hill" while the pair was walking, the affidavit said. "Ms. Logie-Oliver pleaded with me not to arrest Mr. Faulkner," a state trooper wrote in the affidavit. Both denied there was any physical violence.
