A Colorado community sent into a panic over the kidnap-slaying of a 10-year-old girl may learn whether a teenager charged with the crime asks for a trial despite allegedly confessing to police.

Eighteen-year-old Austin Sigg is charged with the murder, kidnapping and sexual assault of Jessica Ridgeway in Denver's western suburbs.

The fifth-grader's disappearance last fall sparked a massive manhunt and fear among residents of Denver's west suburbs. Sigg was arrested after searchers found Jessica's dismembered body in a field.

Sigg was supposed to enter a plea at a March 12 hearing. But his lawyers asked for time to review evidence and analyze his mental state at the time of the crime.
