What to know about the Arizona serial killings that resulted in the death penalty

An Arizona man was sentenced Thursday to death in a string of fatal shootings in metro Phoenix during a three-week span in 2017. Cleophus Cooksey Jr., 43, was found guilty in late September of murder in eight killings. Jurors agreed on the death penalty in six of the killings, but they were undecided on the punishment in the deaths of Cooksey's mother, Rene Cooksey, and stepfather, Edward Nunn.
