Sgt. Tyson Kinney Friday detailed a gruesome scene at the family’s farmhouse, after police were alerted to the killings by the suspect.According to the affidavit, Crossman Jr. contacted police shortly before 4 a.m. Sunday to report he had discovered three family members dead from apparent gunshot wounds in the Pawlet home.The younger Crossman met up with police in the parking lot of the Wells Village School. He was driving his father’s truck, and his clothing was bloodstained, the affidavit said.The younger Crossman, who lives with his mother across the state border in Granville, had been staying with his father for the weekend, according to the affidavit. He told investigators that he went out for a walk hours earlier and returned to the home to find his family members had been killed.Brian Crossman Sr. and Erica Crossman were married in July, Kinney wrote.The affidavit detailed at least two shotguns that were allegedly used in the killings, which were stored in a “gun room” at the home. That room included a gun safe and several cabinets where guns and ammunition were stored, Kinney wrote.In interviews, other family members told investigators that the suspect had a long history of mental health issues. The suspect’s grandmother said her grandson had “a troubled relationship” with his father, which she attributed to those mental health issues, the affidavit said.She also reported that her grandson was “proficient with firearms,” Kinney wrote.Following evidence collection, the suspect was released later Sunday into the custody of New York State Police and was transported to a psychiatric hospital in Glens Falls, according to the affidavit. It was not clear if he was arrested Friday at that facility or elsewhere.In announcing the arrest, state police thanked residents of the small Rutland County community “for their continued patience and understanding as this case unfolded throughout the week.”Alan Keays contributed to this report.CORRECTION: An earlier version of this story had the wrong age of the suspect based on incorrect information provided by the Vermont State Police.Read the story on VTDigger here: Police arrest relative in Pawlet triple murder.
