A convicted murderer who is locked up for killing an Alabama man was reportedly caught live streaming from inside his prison cell and the family of the man he murdered is furious.

"This ain't comfortable for me to be sitting here watching him like he is having fun. It ain't no fun when your family is dead," the murdered man's sister, Chiquita Mushat, told Montgomery's WSFA News when she was shown video of Devin Williamson live streaming from inside Montgomery's Kilby Correctional Facility.

WSFA News reported Williamson used Periscope, a live video streaming app, to broadcast from behind prison walls. The Periscope accounts Williamson was allegedly using have since been deactivated. It remains unclear how long the accounts were active, but it was reportedly long enough for him to amass more than 3,000 followers
