WATERTOWN - A local teen has been charged with attempted murder after using a hatchet to seriously injure an individual he knew Wednesday during a home invasion, police said. The 16-year-old was charged with criminal attempt at murder, home invasion, first-degree assault, first-degree reckless endangerment, first-degree stalking, first-degree burglary and risk of injury. He was ordered detained by a judge and was transferred to juvenile detention with a Thursday court date. Police responded to a Morris Town Line Highway home around 4 p.m. Wednesday for a reported home invasion where the suspect was said to be armed with a hatchet and had injured an occupant. Officers found the injured occupant, a juvenile, had serious injuries to the head, legs and hands consistent with those inflicted by an edged weapon, according to Detective Mark Conway. The juvenile was taken to the hospital. His injuries were deemed serious by not life threatening. Family members told police they heard the intruder and intervened in the assault, distracting the attacker, Conway said. One person called 911 as another chased the suspect, who jumped out a second-story window and ran into the woods with an individual from the house chasing after him, Conway said. Conway said responding officers set up a perimeter between Morris Town Line Highway and Bassett Road, with state police troopers and K-9 units responding to help in the search. As officers searched, they learned the juvenile in the home who was attacked knew the suspect's identity. Conway said the victim identified the suspect as a 16-year-old boy from Watertown. Police reached the teen by phone and he told officers where he was. When he was taken into custody, Conway said, officers recovered a hatchet, a large kitchen knife, a machete, duct tape and binoculars. "Based on the information we have at this time, it is believed that the suspect knew the victim, though (they are) not close friends," Conway said. "The suspect targeted this juvenile specifically and this was not a random home invasion."
