2023 Lewiston shootings
In July 2023, while training at West Point, service members alongside Card noticed his strange behavior and asked for law enforcement assistance. Card had mentioned hearing voices and making threats to "shoot up" a military base in Saco. The New York State Police responded, and he was taken to Keller Army Community Hospital at the academy, where he was committed for two weeks for a medical evaluation. Card's sister-in-law told NBC News that he began hearing voices around the time he got hearing aids. She explained that he was hearing unfamiliar voices and his thoughts were getting mixed up, which was very distressing for him.
