The Cobb County Sheriff’s Office and the U.S. Marshals worked together to arrest a man accused of killing his ex-wife in Marietta.
According to a release sent by the U.S. Marshals, John Kristofak was arrested Thursday morning at a Union City motel. Kristofak was wanted in the death of his ex-wife, Donna Nations Kristofak.
Officials said John Kristofak was taken into custody after a brief struggle. A gun was found during the arrest.
Donna Nations Kristofak, 48, was found unresponsive in Marietta home on Saturday. She was taken to Wellstar Kennesaw Hospital, where she died from her injuries.
Sunday, Cobb County detectives issued a warrant for John Kristofak, 58, on aggravated assault and murder charges.
Monday, Channel 2 Action News found court records that reveal that John Kristofak sent his ex-wife a series of disturbing emails in March.
One read, "I warned you never to cut me off from my children -you did and you will pay. I am not living past tonight so I will do anything to get you back."
Another, written the same day said, "Have you ever been hit by a car going 140, not knowing where it is coming from?"
The paperwork showed Kristofak's ex-wife had a permanent restraining order against him, stating Kristofak should never come within 500 feet of his ex-wife.
