Joseph Christopher was an American serial killer who was active from September 22, 1980 until his arrest on May 10, 1981. He was known as the ".22-Caliber Killer" and the "Midtown Slasher." It is believed that he killed twelve individuals and wounded numerous others, almost all of them African American with one Hispanic male.  The motivation behind the attacks is generally accepted to be deep pathological racism. 
Joseph Christopher's homicidal rampage began on September 22, 1980 when he was twenty-five.  14-year-old Glenn Dunn was shot and killed outside a supermarket in Buffalo, New York.  Dunn was sitting in a stolen car when he died, and witnesses described his assailant as an unidentified "white youth."  The next day, 32-year-old Harold Green was shot while dining at a fast-food restaurant in suburban Cheektowaga.  That evening, 30-year-old Emmanuel Thomas was killed by a sniper while crossing the street to his home, seven blocks from the scene of Dunn's murder.  On September 24, the Christopher moved to nearby Niagara Falls, where he murdered a fourth African American male, Joseph McCoy.
