A Cobb County man facing trial for murdering his ex-wife, plead guilty on Tuesday May 21, to killing her in their once home. John S. Kristofak, 58, was married to Donna Nations Kristofak for 19 years before their divorce in August 2011. One month after the divorce, Donna filed for a restraining order. John S. Kristofak continued to harass her. He allegedly sent her threatening emails that contained comments such as, “You are in danger- No one can help you at this point. You won’t know where it is coming from.” He also would call her at work using vulgar language to her and her coworkers, and put up posters with vulgar things in the front of her house. He was arrested a few weeks later for chasing her through a WalMart parking lot. A butcher knife and suicide note were found by police in his car.
When he was released from probation, Donna said that she feared for her life. Her 17-year-old son then found her unresponsive in their garage three days before Christmas. She died later at WellStar Hospital in Marietta. John Kristofak was found and arrested 5 days later.
John Kristofak pleaded guilty to malice murder and possession of a firearm during commission of a felony. He is also sentenced to five years in prison for the weapon charge and another 10 years for the probation violation of stalking Donna.
