A teenage Texas girl received two life sentences and 25 more years in prison for her role in the murders of her mother and two young brothers in the family's home.
Erin Caffey, 17, could be eligible for parole when she's 59 under a plea agreement, according to her William McDowell.
Caffey's trial was scheduled to begin next month in Hopkins County.
Prosecutors didn't plan to seek the death penalty against her.
Co-defendant Bobbi Gale Johnson was sentenced to 40 years in prison and may be eligible for parole in 20 years.
Johnson was named in an affidavit as an accomplice who did not use a weapon.
Police believe Caffey and Johnson waited in a car down the road from Caffey's home in Alba during the attack in March.
Authorities say Charlie James Wilkinson, 19, who was Caffey's boyfriend, and Charles Allen Waid, 20, went on a shooting and stabbing rampage before setting fire to the home.
The attack left Penny Caffey, 37, and her sons Mathew, 13, and Tyler, 8, dead.
The father, 41-year-old Terry Caffey, was shot five times but got out of his burning house and reached his neighbors.
Authorities say the murder plot was hatched because Erin Caffey's parents didn't want Wilkinson to date their daughter, who was 16 at the time of the crime.
In November, Wilkinson and Waid avoided the death penalty by pleading guilty for their involvement in the killings.
McDowell said both would most likely receive life sentences with the possibility of parole.
