Ann Plotkin plead guilty to three counts of complicity to murder Friday in Trigg County Circuit Court.
Plotkin was arrested in early 2015, accused of helping Ryan Champion plan the 2014 murders of his parents, Lindsey and Joy Champion, and his sister, Emily Champion.
After entering her plea she requested to be sentenced immediately, which Circuit Court Judge C.A. Woodall granted.
Judge Woodall sentenced Plotkin to 22 years in prison with credit for time already served. She must serve 85-percent of her sentence before she is eligible for parole.
