- "I just gotta wait a little bit longer so my biggest goal is to do as much damage as I can but the fact of the matter is you don’t have a lot of time."
- —Randy Stair explaining in a now deleted YouTube video how he hoped to carry out the shooting.
Randy Stair (September 17th, 1992 – June 8th, 2017), also known by his online pseudonym Andrew Blaze, was a mentally ill American who resided in Dallas, Pennsylvania. He murdered 3 of his co-workers at a local Weis Supermarket and shortly thereafter killed himself. After the shooting, it was discovered Stair had left a big social media footprint, especially on YouTube. He was most notably obsessed with the character Ember from the Nickelodeon cartoon Danny Phantom, and even went as far as to make a fictional group of girls all based on the character called "Ember's Ghost Squad". Though Stair did not commit a school shooting, he idolized the Columbine High School shooters Eric Harris and Dylan Klebold, wrote about committing a school shooting, made an animated video of a school shooting, and wrote that “Weis Markets is officially Columbine High School.”
He also believed he was a woman trapped in a man's body (Transgender) and would often cross dress when his family wasn't home, according to him in a video.
