It’s entirely possible, and if so, I’m sure they’ll get to the bottom of it soon. A medical resident named Anthony Garcia, carried out a series of revenge attacks against former faculty members. In one attack, he killed an 11 year old boy, and a housekeeper, who happened to be in the home at the time. Law enforcement did a deep dive into his (the boy’s) gaming system, including interviewing people he had played with. Ultimately it turned up nothing, but if she played games, I’m confident they would have explored that angle.
