A wedding reception in New Rockford, North Dakota, on the night of Saturday, September 5, 2015, ended in a fatal shooting. Donnie Perleberg, 41, of Pingree, was seated at a table with a woman when a man approached from behind and fired. Perleberg was struck in the back of the head and died at the Eagles Club; the woman beside him, later identified as Mary Seiler, was shot in the neck and stomach and taken to a Bismarck hospital.

Officers arrested 51-year-old David Troske of New Rockford at the scene without resistance and recovered a small-caliber handgun. Witnesses said Troske had been Seiler’s ex-boyfriend and had been seen earlier that evening with Seiler and Perleberg; reports indicate he left the reception, returned with a firearm, and opened fire.

Does anyone who attended the Eagles Club that night or knew Perleberg or Seiler have information that could shed light on what led to the shooting?
