At the time of his murder, Grover was the head coach at Mr. Todd’s Gymnastics in Poughkeepsie. According to his obituary, Grover graduated from Red Hook High School in 2006. He previously coached gymnastics at Fly High Gymnastics in Red Hook. Investigators began what was described as a "painstaking six-month investigation" involving phone records, internet searches, computer forensics, dozens of interviews, and more to determine there were inconsistencies in Addimando's alleged history of abuse and her claims of self-defense. There was also overwhelming evidence the murder was intentional, officials say.
