David Carpin, 61, was killed in the fall of 2017 in the rural Malone/Duane area of northern New York. He was missing for months before a tip in April 2018 led state police to a property on Old Meacham Road, where a shallow grave was found containing his body. The shooting itself reportedly occurred in November 2017 at a home across the street that John J. Castner was renting for his daughter.

Investigators focused on 61-year-old acquaintance John J. Castner and his 37-year-old daughter Melissa L. Castner. John Castner confessed that he shot Carpin in the chest with a .45-caliber Smith and Wesson. Melissa was initially charged with second-degree assault based on an allegation she had attacked Carpin with a knife, but that charge was dropped after an autopsy found no stab wounds. Both later avoided trial by pleading to reduced charges: John to first-degree manslaughter, receiving 15 years in state prison, and Melissa to first-degree hindering prosecution, receiving one-and-one-third to four years.

No definitive motive has been publicly released. Did anyone in the Malone or Duane area know David Carpin, his movements in late 2017, or have information about his relationships with the Castners?
