Chakaya Brittney Folborg, 24, pleaded guilty to killing her sister,
Kourtney Dyches, at their Mableton home on Feb. 20, 2012.
The case had been set to go to trial on Monday, April 28.
“This victim was a vibrant young lady with the rest
of her life ahead of her. The defendant, without any provocation, took a
knife from the kitchen some two hours before the killing and waited
until the victim was in the shower before viciously
stabbing her at least six times,” Sherwin Figueroa, assistant
district attorney, said in a news release.
The sisters were both 21 years old at the time. Folborg had been adopted into the family as an infant.
After accepting the plea, Cobb Superior Court Judge S. Lark Ingram sentenced Folborg to life in prison. She will be eligible for parole after serving 30 years. She has been held at Cobb Jail without bond since her arrest at the scene.
