A Cedar Rapids police investigator testified during a hearing Friday that Bobbie Little told him in June 2014 that he killed his “best friend” in a “rage” over drugs. Investigator Jeff Holst testified about an audiotape of the jail interview played for the judge. In the tape, Little repeatedly denied hurting Shanna Beyhl, 37, on April 4, 2014 but then when he was confronted by the fact that his shorts had blood on them that tested as being Beyhl’s blood, he admitted Beyhl wouldn’t give him drugs, so he grabbed her neck and stabbed her in the stomach on April 6, 2014.Holst also said Little, 32, of Cedar Rapids, understood his right to a lawyer and to remain silent and agreed to talk to investigators.
