The Douglas County teenager accused of murdering his great-grandmother with a sword and wounding his grandmother has appeared before a judge to hear the charges against him.

Fourteen-year-old Gevin Allen Prince faces a count of malice murder, and four counts of aggravated assault.  David McDade, the Douglas County district attorney, says two of the assault charges involve Prince allegedly chasing two young neighbors with the sword as they tried to stop the attack.  Neither was injured. 

Prince told the judge, when asked, that he did understand the charges being brought against him.

Chief Deputy Stan Copeland with the Douglas County Sheriff's Office tells WSB the motive behind the stabbing on Spring Ridge Drive Monday afternoon was because Prince did not want to halt his leisure time to begin doing his chores.

"It appears that the defendant was upset over a conflict with the grandmother over a video or computer game," said Copeland.

The victim has been identified as Mary Joan Gibbs, the teen's 77-year-old great grandmother.  Inside the house, they found the teen's 55-year-old grandmother with a stab wound to her arm.  Copeland says Laura Prince managed to survive by barricading herself inside a room.  Both had been stabbed with a sword.

Copeland says when they went to arrest the teen, he was not going down without a fight.

"He was in the doorway.  He was actually utilizing a pellet rifle and shooting at deputies, but it was with a pellet rifle. He shot a couple of patrol car windows out and was threatening with a sword, so he was a little agitated," said Copeland.

Copeland says the teen was arrested in June on a similar incident in which he was wielding a different sword.  He got into trouble again in July.  Both times he was sent to a mental institution but was eventually released.
