This is where Mudgett and others say the mystery begins. According to newspaper accounts, Holmes was marched to the gallows at Moyamensing Prison where he was hanged. The prison was located on 1400 South 10th Street in Philadelphia before it closed in 1963 and was demolished in 1968. Holmes’ body was eventually interred at Holy Cross Cemetery in Yeadon. Holmes requested his casket be encased in concrete so no one would steal his body. However, an 1898 newspaper article sparked the conspiracy theory that Holmes somehow escaped death at Moyamensing and ended up in South America. Fast-forward to 2017 with Mudgett standing in what many believe to be the grave of his murderous relative. Descendants of Holmes were granted permission by a Delaware County judge to exhume the remains.
