CHEYENNE, Wyo. (AP) - The Wyoming Supreme Court has upheld a Laramie man's attempted-rape conviction in a cold case dating from 1972.

A jury last year acquitted Lance David Bean of Laramie of charges of rape and murder in the death of 20-year-old Sharon Reher.

The jury convicted Bean of attempted rape. A judge sentenced Bean to five years of probation.

Prosecutors said Bean was at a party at Reher's Laramie residence the night before she was found dead from a stab wound.

Investigators testified during Bean's trial that recent testing showed DNA from Bean's skin on Reher's clothing.

Bean appealed his conviction to the Wyoming Supreme Court. His lawyer argued on appeal there was no proof Bean was involved in any crime.
