COLORADO SPRINGS, Colo. — A gunman who police say staged a deadly attack on a Planned Parenthood clinic was a recluse who stashed food in the woods, avoided eye contact, warned neighbors about government spying and passed out anti-Obama pamphlets, those who knew him said. Authorities say Robert Lewis Dear, 57, killed three people, including a police officer, during an hours-long standoff before surrendering at the Colorado Springs clinic. Police have not disclosed a motive, but the city's mayor, John Suthers, said people can make "inferences from where it took place," referring to the clinic.
