He has returned and showed up outside of last night's NXT TV tapings.
The man who was shot by a police officer outside of the WWE Performance Center in 2015, Armando Alejandro Montalvo uploaded a number of videos onto his Instagram page of him talking about the WWE, discussing starting a "wrestling crew" and the last video that is shown will be of him outside of Full Sail yelling in public about how his private areas are bigger than D Generation-X's.
The reason that Armando Alejandro Montalvo was shot outside of the PC in 2015 is because he was reportedly being a major disturbance outside of the building; which caused for the police to be called. He charged at one of the officers and that led to the officer opening fire.
