Xavier Alexander Parks had only been out of jail for two days when his girlfriend tried to break up with him.
Released from the Clayton County Jail, where he had been serving a sentence for violating a domestic-violence-related probationary sentence, Parks didn't have any place to stay, according to police. In court documents, he was called homeless.
Parks apparently went to see his 16-year-old girlfriend, the mother of his child, according to police, and she tried to end their relationship.
Parks, now 21, allegedly stabbed Antoinette McDonald multiple times in the neck and killed her. He was indicted by a grand jury on Wednesday on charges of murder and aggravated assault.
In court documents, Clayton County Police Detective David Robinson summarized the case simply: McDonald "wanted to end their relationship, due to their past problems" and Parks stabbed her "numerous times on and about the neck with a knife."
According to the indictment, McDonald's throat was cut, in the attack, and her jugular vein was severed.
When officers arrived at the Riverdale-area apartment where the two fought, McDonald allegedly gave her boyfriend's name to the police with her dying breath.
Witnesses -- who lived in the apartment with McDonald -- told detectives they saw a verbal argument between the pair escalating, and walked out to see the older Parks stabbing his teenage girlfriend. One witness, a 42-year-old woman who doesn't appear to be related to McDonald or Parks, told the police she grabbed Parks by the hair, dragged him out of the house, and locked the door.
Parks was arrested about three hours after the incident, according to police, when he called 911 and turned himself in.
He cooperated with the detectives to some extent, telling them where he had hidden the knife that is suspected of having been used to kill McDonald, and where he had hidden a bloody pair of pants.
Parks' next court date has not yet been set. He faces the possibility of a life sentence.
