Deputy William Hauley Coleman, 50, a 20-year veteran of the Maricopa County Sheriff’s Office, was killed in the early morning of January 8, 2012, while responding to a burglary call in Anthem, Arizona. Deputies arrived around 4:15 a.m. at a medical building near Anthem Way and Gavilan Peak Parkway and encountered a man inside a van. As deputies attempted contact, the man opened fire with a rifle. Deputy Coleman was struck below his bulletproof vest, transported to a local hospital, and later died of his wounds.

The shooter was killed by return fire from other deputies at the scene and identified as 30-year-old former Marine Drew Ryan Maras. Investigators later linked the same rifle to the murders of a New Hampshire couple, James Johnson and Carol Raynsford, near Sedona two days earlier. Two other men, Michael Allen Pierce, 33, and Shawn Patrick Brannen, 23, were arrested in connection with the burglary at the medical center, though authorities said it was unlikely they were involved in Deputy Coleman’s killing.

Are there witnesses who remember activity around Anthem Way and Gavilan Peak Parkway that morning or who have information about the van encountered by deputies?
