An Arvada woman serving 30 years in prison for throwing parties for high school boys where she provided alcohol and drugs and had sex with some has pleaded guilty to a felony violation of conditions of her bond.
Silvia Johnson was awaiting sentencing in that case when she was involved in a traffic accident in September that injured her, a 14 year old girl who was driving, and two boys, ages 11 and 12, one of whom is her son.
While she was free on bond, she was supposed to avoid contact with those children.
Jefferson County district attorney's spokeswoman Pam Russell says Johnson faces at least one additional year in prison when she is sentenced May 19th.
In July, Johnson pleaded guilty to two misdemeanor counts of sexual assault and nine felony counts of contributing to the delinquency of a minor.
As part of her plea agreement, prosecutors dropped two counts of distributing methamphetamine.
