Six months after his death, David M. and Stacy L. Morse are still seeking answers about why their 21-year-old son died after having a medical emergency while training at the state Academy of Fire Science, Montour Falls, on March 3. Brian A. Benjamin asking for an independent investigation, Mr. Morse wrote that Peyton “was having trouble breathing, asked for help, and was placed at the back of the evolution box, and the instructor sat on the top.” Once the coroner’s office made its determination, the state police investigator might have decided that’s all he needed to conclude that there was nothing more to Peyton’s death and to decide not to pursue the investigation further, the parents surmised.
