Redner had been in Ganly's Pub & Restaurant less than a quarter-mile from his house on the night before he was found dead.
But authorities say they are not aware of any trouble at the establishment before he left.
State police say they are working around the clock to try to solve the murder. Lt. Thomas G. McDaniel says investigators are looking at a variety of possible motives.
The family has put up $10,000 to raise to $20,000 the reward offered for information leading to an arrest.
