On Tuesday, jurors listened to the second day of testimony in the murder trail of 49 year old Peter Robinson of Bradford. Robinson is on trial at the Penobscot Judicial Center in Bangor for the beating death of 71 year old David Trask of Hudson. Neighbors and acquaintances of both men took the stand, talking about the history of land disputes between the two families.A former game warden who responded to an argument between Robinson and members of the Trask family in 2009 testified that Robinson told him, if he caught them down on his land again, “he would probably kill them.”Trask died in November 2011. The Medical Examiner who autopsied his body also testified saying the death was from blunt head injuries.Police say Trask came at Robinson with a crowbar during a dispute and Robinson grabbed the bar and beat Trask to death. Robinson is claiming self-defense.The trial resumes on Wednesday.
