"We've located some people independent of the house who saw someone leave,'' Sharon Police Chief Raymond C. Greene said Sunday evening. "It was one person. We don't have any names yet.''
Jeremy was shot at about 1 a.m. Saturday and died of a single shotgun blast to the right neck and shoulder area, police said.
The Sharon High School eighth-grader and three other teens were watching television in the living room when they heard the back storm door open, police said. Jeremy went to investigate and the other teens, two boys and a girl, heard a shot and saw Jeremy drop to the floor, police said.
Police were responding to a report of shots fired when they found Jeremy in an inside doorway. The weapon, believed to be a 12-gauge shotgun, had not been found.
