Dennis Whitney

Dennis Manaford Whitney (August 15, 1942 – April 24, 2005) was an American spree killer who shot and killed seven people in early 1960. Whitney then progressed his way to Phoenix, Arizona, where on February 20, he shot to death 55-year-old Ira Lee Hardison and 40-year-old Spencer Frazier hours apart from one another. Whitney stole Frazier's car and drove until it broke down the next day in Tucson.

With a broken down vehicle and stranded 470 miles away from home, Whitney resorted to another gas station robbery, which ended with 27-year-old Glen B. Smith being killed and Whitney pocketing $104.

In 1972, Whitney's death sentence was commuted to life imprisonment after Furman v. Georgia ruled that the death penalty was unconstitutional. Whitney died of unspecified causes in 2005, after serving 44 years in prison.
