A disturbing video posted online in 2016 by Randy Stair, who later killed three co-workers at a Pennsylvania supermarket, contained graphic threats directed at an online friend.

The revelation comes from an online acquaintance of Stair's, who spoke about the video and its contents in the wake of the 2017 shooting. The video, which has since been removed from public view, reportedly depicted Stair in a violent and threatening manner, specifically targeting the friend with whom he communicated online.

According to the friend, the video was deeply unsettling, featuring explicit threats and disturbing imagery. While the exact nature of the threats remains undisclosed, the friend described it as a clear indication of Stair's escalating distress and violent intentions. This online communication and the subsequent video serve as a chilling precursor to the events that unfolded less than a year later.

The existence of this threatening video raises significant questions about the potential for early intervention and the ability of online platforms to identify and report such dangerous content. Experts in online behavior and threat assessment note that while not all online threats lead to real-world violence, they can be crucial indicators of an individual's state of mind and potential for harm.

Stair carried out the deadly attack at the Weis Markets in Tunkhannock, Pennsylvania, on June 7, 2017. He shot and killed three colleagues before taking his own life. Investigators at the time pieced together Stair's background, looking for motives and any signs that might have predicted the violence.

The online friend's account of the 2016 video provides a new, disturbing layer to the understanding of Stair's mental state and his interactions leading up to the massacre. The friend indicated that while they had communicated with Stair online, the graphic nature of the video was a significant escalation that caused them considerable fear.

This information highlights the complex challenges faced by law enforcement and social media companies in monitoring online activity for potential threats. The difficulty lies in distinguishing between expressions of anger or distress and credible threats of violence, as well as in having the legal and technical means to intervene effectively.

Further examination of Stair's online footprint and the content of the video, as described by his online acquaintance, could offer crucial insights into the psychological factors that contributed to the supermarket shooting, potentially informing future prevention strategies.
