NOT GUILTY: A Princeton man on trial for the killing of his brother has been declared legally insane by a Trenton judge. The ruling means that Matthew Hertgen will be committed to a mental health facility instead of serving life in prison for the murder of his brother Joe Hertgen. Doctors who examined Hertgen, from both the state and defense, agreed that the 32-year-old has been suffering from schizophrenia for several years. They say those symptoms led to delusions and paranoia, leaving him unable to comprehend what he was doing when he attacked his brother with a golf club and knife on Feb. 22, 2025. . . . #News12NJ #NotGuilty #NewJersey #Princeton #News12
