Talk:The Columbine Killers' 3 Unreleased "Basement Tapes" (Recorded in 1999)/@comment-26991402-20170410162551/@comment-26991402-20170509053409

I forgot where I read it but they did keep a backup. But the police MUST keep a backup file of the basement tapes as they are used for police training. A friend of mine has a father in the police force there and her brother just joined and he told me that for training, they watched the basement tapes and analyzed signs and such and focused a lot on the tape where they made the bombs and all. They must keep this as evidene as the case hasn't exactly been solved yet for motive has not been found.
