GILLETTE, Wyo. (AP) - A former day care worker at Campbell County Memorial Hospital entered a no contest plea to a charge that he molested a child at the day care. Shawn A. Hart, 22, entered his plea Thursday to a charge of taking immodest, immoral or indecent liberties with a child. Two other molestation charges were dropped. The children involved were all under the age of 6. A sentencing date has not been set. Prosecutors say the molestation happened in either June or July of 2006 at the hospital's day care. Hospital spokeswoman Karen Clarke said Hart began working at the day care in May 2006 and was fired in December 2006, shortly after the abuse came to light. Clarke said the hospital conducted a criminal background check before hiring Hart. Hospital CEO Bob Morasko declined comment.
