WRONGFUL EVICTION, Please HELP!?

My sister is a resident of Colorado. She has legal custody of our nephew (16) who resides with her. She had just renewed her lease with this apartment complex. After renewing the lease a burglary occured at the complex. My 16 year old nephew was accused of the burglary. Because of being in rehab the year before he was on probation he was immediately sent to a youth detention center. He insisted he had no involvement although his finger prints were on the accusers outside window. (He admitted staring in the apartment when it was empty prior to the tenant moving in.) When he was arrested my sister was given a 3 day eviction notice and was told she had to continue paying the $1300 a month rent until it was rented or the lease was up. She abided- and moved out, has paid one month rent since being gone. My nephew had a trial and was found not guilty. Does she have to continue paying this rent? Does she have a case for wrongful eviction since he was found not guilty? HELP!
