Investigators with the Alabama Department of Corrections are looking into a video that has gone viral from inside one of their facilities, showing a large group of inmates taking part in the Mannequin Challenge. One scene seems to be acting out a stabbing, and in another three men pretend to beat another inmate on the ground. The original post on Facebook, uploaded by an unofficial account, read: ‘Free us… prison reform… free my family!’ The post, which alludes to being the work of a prisoner, included the hashtags #ALLlivesMATTER, #GodLovesAll, and #ChaingangChallange.
