One of three teens who was charged with killing a 20-year-old woman while throwing large rocks at passing cars in Colorado pleaded guilty on Friday to reduced charges under a plea agreement, prosecutors said. The deal reached with Zachary Kwak, 19, requires him to cooperate in the prosecution of the two other teens still being prosecuted on first-degree murder charges in the death of Alexa Bartell.
In exchange for Kwak's guilty pleas to those charges, prosecutors dropped other more serious charges against him, including first-degree murder. Kwak faces between 20 and 32 years in prison, prosecutors said. He will not be sentenced until Sept. 3, after Karol-Chik and Koenig are scheduled to be tried separately. Karol-Chik's lawyer, Holly Gummerson, declined to comment on the plea deal or the allegations against her client.
