Question: what happened to morgan on criminal minds when he was young

title: Derek Morgan (Criminal Minds)
text: Years later , Morgan 's past would come back to haunt him when he was arrested by the Chicago Police Department for the murder of the unidentified boy and two others . The lead detective , who had arrested Morgan several times for juvenile misdemeanors when the latter was young , believed Morgan was guilty and used a BAU profile done by Jason Gideon ( Mandy Patinkin ) to support his case . Believing he was being framed by the real killer , the BAU searched through Morgan 's life and background to prove him innocent , which discomfited Garcia as Morgan had been generally reticent about the details of his past . They later identified Carl Buford as the man who set Morgan up to take the fall ( Buford was friends with the lead detective ) . When Hotch asked about Buford , Morgan told him to back off . He then escaped police custody and spoke to a local boy who was friends with the latest victim . The boy revealed he was currently being molested by Buford and that the latest victim knew about it . Morgan confronted Buford , who at first denied anything happened between them , and told Morgan the other boy was lying . Refusing to back down ( and wishing that he had told someone about Buford when he was a kid ) , Morgan eventually got Buford to admit to the abuse . Buford 's admission was overheard by Chicago PD detectives who were lying in wait nearby , and they arrested Buford . Buford pleaded with Morgan to help him , to which Morgan replies , `` You go to Hell , '' leaving the child molester to his fate .
