Deadly Shooting Spree Motivated by Hatred for Drugs and Homelessness, Court Docs Reveal.

Court documents reveal that a man's hatred for drugs and homelessness led him to go on a deadly shooting spree in two Arizona cities, killing four people and injuring one. The suspect, Iren Byers, allegedly shot his victims in the head after they talked about using fentanyl, a drug that Byers' brother also abused. Byers admitted to all five shootings and is being held with no bond on four counts of first-degree murder and one count of attempted first-degree murder.
