>In June 2021, police in Broome County were called by officials of a local high school who told them Gendron had threatened violence in comments made to fellow students.
>“A school official reported that this very troubled young man had made statements indicating that he wanted to do a shooting, either at a graduation ceremony, or sometime after,” the same government official familiar with the case told The News.
>State Police were sent to investigate and Gendron, under a section of state mental health laws, was referred for a mental health evaluation and counseling, the official said.
He was already on law enforcement's radar almost a year before this happened.
