The End of the CraigsList Serial Rapist

Maj. Daniel Dusseau's head throbbed. It was 9 p.m. and nine months into the pursuit of a rapist whose attacks had haunted nearly a dozen of his detectives, sergeants and lieutenants. Only they and nine female victims knew all of the sadistic signatures of the serial rapist the police had been chasing: green rubber gloves, a ski mask, a digital camera and a .22-caliber handgun.

They knew that he had raped women for hours at gunpoint across Prince George's County, snapping pictures and threatening them with death. They knew that he had found them all, professional escorts, through online ads, all but one on Craigslist. They believed that his name was Mark Humphries and that he was so bold he would never stop until he was caught. They also knew that an arrest wouldn't come easily. He had proved so cautious that he left almost no evidence with each attack
