The suspect in a triple homicide on Saturday in Davenport, Florida was driving back home toward Pennsylvania on Friday when he hatched his deadly plan to kill co-workers, Polk County Sheriff Grady Judd said Monday. He got as far as Cordele, Georgia, before turning around and putting it into motion, Judd said. Three people were killed in the attack at a house that was shared by eight people, the Lakeland Ledger reports. Two were killed at the scene and another at the hospital. Another resident of the house was injured, but did not suffer life-threatening injuries. Three other people escaped without harm. 39-year-old Shaun Paul Runyon was arrested Saturday after a two-hour manhunt. He's charged with three counts of first-degree murder. Runyon was part of a group of electrical contractors working at a construction site in Lakeland on behalf of J-N-B Electric out of Pennsylvania.
