John Joseph Labbe was 54 when he was found dead on his property at 761 Texas Hill Road in Plymouth, New Hampshire. On September 8, 2011 a friend discovered his body in a shed; an autopsy determined the cause of death to be gunshot wounds and the manner of death was ruled a homicide.

The investigation remained active in the years afterward and was later handled by the New Hampshire Cold Case Unit. Despite public tips and a $10,000 reward offered by his family in 2013, no arrests have been announced and no suspects have been publicly named. Investigators have specifically sought information about Labbe’s activities between September 6 and September 8, 2011.

If anyone knew John Labbe or saw him in the days before his death, does any detail about his movements between September 6 and September 8, 2011 stand out?
