Final answer:
Floyd Wells was a key informant in the Clutter case, but his life after the case is not well-documented. Truman Capote included him in 'In Cold Blood' to highlight his role in solving the crime.
Step-by-step explanation:
Floyd Wells was a former employee of the Clutter family and an inmate at the Kansas State Penitentiary when he provided a tip to the authorities that led to the arrest of Richard Hickock and Perry Smith for the Clutter family murders. After the trial and execution of Hickock and Smith, Floyd Wells's life post-Clutter case isn't well-documented in Truman Capote's
In Cold Blood, as the book focuses more on the perpetrators and the investigation rather than the informants. Capote included information about Wells because his tip was instrumental in solving the case, providing insight into how the killers were identified and illustrating the importance of informants in criminal investigations.
