ATLANTIC CITY — A convicted murderer who was released Friday after 30 years in prison was arrested Sunday for allegedly beating his mother to death in her home reports authorities.

Steven Pratt, 45, of Atlantic City, faces murder charges for the second time after having been free for less than 2 days.

Authorities are trying to figure out what exactly went wrong with this reunion, what drove a man who had just spent 3 decades behind bars to do such a horrific thing to his own mother; or did it have something to do with him and her before his incarceration?
