PHOENIX — A serial killer convicted of murdering six people in a shooting spree that terrorized Phoenix in 2005 and 2006 was found dead Wednesday in his death row prison cell, officials said.
Dale Hausner, 40, was found unresponsive around noon Wednesday in his one-person cell at the Eyman state prison complex in Florence, the Department of Corrections said. He was pronounced dead at a hospital about an hour later.
Hausner's death was under investigation and the cause was unknown.
Hausner, a former airport janitor, was given six death sentences and hundreds of years in prison for killing six people and attacking 19 others in a series of random shootings in the Phoenix area. He denied any involvement in the attacks and suggested his former roommate might have carried out some of the crimes.
Authorities say Hausner preyed on pedestrians, bicyclists and animals in attacks that ended in August 2006 when he and roommate Sam Dieteman were arrested at the apartment they shared in Mesa. Inside, police found guns, news clippings of the killings and a city map marked with the locations of some of the shootings.
Dieteman, who pleaded guilty in two of the killings and was sentenced to life in prison, testified against Hausner, saying they cruised around late at night looking for strangers to shoot.
The "serial shooter" attacks and an unrelated serial killer case kept neighborhood watch groups on high alert in the summer of 2006. Families stayed inside and authorities called meetings that drew hundreds of people who learned more about the attacks and were encouraged to provide tips.
Police said their big break came when one of Dieteman's drinking buddies, Ron Horton, called police to say Dieteman had bragged about shooting people.
