A father and daughter were sentenced Monday for their involvement in a November 2017 killing in the town of Duane.

John Castner, 62, and his daughter Melissa Castner, 37, pleaded guilty in February: he to first-degree manslaughter and second-degree criminal possession of a weapon, and she to first-degree hindering prosecution.

On Monday in Franklin County Court in Malone, John was sentenced to 15 years in state prison for the manslaughter charge and 10 years in state prison for the weapon charge, to be served at the same time. Each charge also carried five years of post-release supervision.

“It was agreeable,” said county Public Defender Thomas Soucia. “Mr. Castner, at 62 years old, when you start talking about 15 years or longer time, you have to take into account that that might mean the rest of his life.”

Melissa was sentenced to one-and-one-third to four years in state prison for hindering prosecution in March and April 2018. Melissa was represented by Conflict Defendant Claire Knittel, who could not be contacted by press time.

The sentences were determined through conversations between the district attorney, Soucia and Judge Robert Main Jr.

Both Castners were charged in relation to the shooting death of David Carpin, 61, of Duane in November 2017. Carpin died of a gunshot wound to the chest from a .45-caliber Smith and Wesson on Nov. 28, 2017, State Police said in 2018.

State Police discovered Carpin’s body in April 2018 at 355 Old Meacham Road, a property owned by John Castner that is across the street from where the shooting happened at 344 Old Meacham Road, a home John had been renting for Melissa.

Melissa was alleged to have “wrongfully compelled or attempted to compel” another person with information relating to a “criminal transaction” to refrain from sharing that information with a grand jury, prosecutor, law enforcement officer or court. The crux of this alleged action was “by means of instilling in him a fear that the Defendant (Melissa Castner) would cause physical injury to such a person.”

Soucia said murder trials take a long time, involving thousands of pages, long negotiations and many county officials.

“Doing trials takes a lot of time on everyone’s part,” Soucia said. “I don’t have a problem with doing trials, but at the same time you have to take at look at the resources available to the county and you also have to look at what really serves justice.”
