A third victim of a brutal attack on contractors living in a shared home in Central Florida died of his injuries Saturday evening. According to the Polk County Sheriff's Office, two people were killed and another critically injured by a disgruntled co-worker early Saturday in Windsor Island Resort in Davenport. Another was beaten on the street while trying to flee, but did not suffer life-threatening injuries. The suspect, Shaun Paul Runyon, 39, has been charged with three counts of first-degree murder and one count of aggravated battery. The contractors, who worked for J&B Electric out of Pennsylvania, were staying together at the home while performing work for Publix Super Markets.
