Robert McKenna, a 43-year-old man, was found dead inside his home on Damons Point Road in Marshfield, Massachusetts on September 16, 2015. A friend discovered the body and investigators described the scene as horrific. The cause of death was listed as exsanguination from severe wounds to his arm and head.

Police said the attack began as a robbery that turned violent and that several firearms were later reported stolen from McKenna’s home. Investigators told reporters they did not believe the killing was random and that McKenna had been specifically targeted; neighbors mentioned McKenna’s past activities, including big-game hunting and dealings in diamonds, as background that surfaced during the inquiry.

The probe produced multiple arrests, including one tied to DNA found at the scene and others later accused of taking part in planning and carrying out the home invasion. Does anyone have information about McKenna, his household, or movements in Marshfield around September 2015?
