You mentioned "wack DA's"; made me think of Gricar:
"The district attorney who tried and failed to prosecute Jerry Sandusky in 1998 after reports of sexual abuse emerged, has been missing since 2005 and was declared legally dead in July. Ray Gricar disappeared on April 15 six years ago after telling his girlfriend he was going for a drive. His body was never found, only his abandoned car and his laptop which had been tossed in the Susquehanna River in Pennsylvania without its hard drive.
In 1998, Gricar had attempted to bring a case against Penn State former football defence coordinator Jerry Sandusky on child rape charges. "
