An 18-year-old who was 16 when she carried out a double stabbing that killed one teen and injured another will be sentenced as an adult next year.
Inessa Lyons pleaded guilty Friday in Omaha's federal court to voluntary manslaughter and a weapons count in the 2008 stabbing on the Omaha Indian Reservation in Macy, Nebraska.
The U.S. Attorney's Office says Lyons fought with the girls at a late-night party before stabbing them both, killing 15-year-old LaTressa Lee Walker and wounding another 18-year-old girl.
Lyons was charged as an adult. She faces up to 25 years in federal prison when she's sentenced on February 14th.
