Dale Hausner and Samuel Dieteman were a duo of serial killers, arsonists and thrill killers who committed several drive-by shootings and arson in Phoenix, Arizona, between May 2005 and August 2006. They targeted random pedestrians and animals, mostly doing so while under the influence of methamphetamine, and also set fire to multiple objects. Investigations of their crimes coincided with the search for the Baseline Killer, who was also committing random murders and sexual assaults in the Phoenix area.
