It happened Sunday afternoon at the Home Depot on Hesperian Boulevard when a man tried to walk out without paying for items.
Police say the loss prevention officers confronted the man, who then shot one officer in the shoulder and pistol-whipped the other.
Across the street police found a bloody shirt, a baseball cap, and what looked to be human hair. They believe the suspect has changed his looks.
Both security officers sustained non-life threatening injuries and will recover.
