Robert Pierog, a 22-year-old white man, was found outside an apartment building on West Main Street in Littleton, New Hampshire on the evening of May 27, 2016. Police responding to an emergency call at about 10:30 p.m. discovered Pierog suffering from multiple gunshot wounds; he was pronounced dead at the scene and an autopsy ruled the manner of death a homicide from multiple gunshot injuries.

Investigators identified and arrested three people in connection with the killing. Damion Yeargle, 21, of Littleton, was charged with first-degree murder and is accused of firing the shots. Eighteen-year-old Quade Kadle of Jefferson was charged as an accomplice to first-degree murder and later pleaded guilty to conspiracy to commit murder and conspiracy to commit witness tampering. A third man, 21-year-old Nick Skidmore of Littleton, was charged with conspiracy to commit murder and hindering apprehension or prosecution. Authorities described the motive as retaliation for Pierog’s cooperation with law enforcement as a confidential informant.

Does anyone have information about Pierog, where he spent his time around May 27, 2016, or anything that could help clarify the events that night?
