DENVER - A possible plea deal is in the works for the teenager accused of kidnapping and murdering Jessica Ridgeway.
A plea deal in the Austin Sigg case is expected to be revealed Tuesday afternoon in Jefferson County court.
Sigg is charged with first-degree murder, kidnapping and sexual assault, among other charges.
Investigators say Sigg confessed to murdering the 10-year-old Westminster girl who was kidnapped on her way to school last October.
Jury selection has been completed and opening arguments were set to begin Thursday.
9news legal analyst Scott Robinson anticipates the plea could also involve charges tied to an attempted kidnapping involving Sigg and a 22 year-old woman at Ketner Lake in May of 2012, about five months before Ridgeway disappeared.
Robinson said the Ketner Lake case could add several years to Sigg's sentence. For prosecutors to accept a plea, they would want to assurance Sigg would be getting as much jail time as possible.
If convicted, he would face life in prison but could be paroled after 40 years. He can't get the death penalty because he was 17 at the time of the slaying.
