Defendant in stabbing case pleads not guilty by reason of insanity.

HART — A 46-year-old Detroit man accused of stabbing a man and assaulting another man and woman at the Lucky Lake Campground in Grant Township a year ago pleaded not guilty by reason of insanity in 51st Circuit Court Monday, Aug. 1.

Mario Louis Corsetti will remain in the Oceana County Jail until a bed is available at the Center for Forensic Psychiatry in Saline, Michigan, said Oceana County Prosecutor Joseph Bizon. Corsetti will be subject to a 60-day hospitalization for diagnostic testing. Psychiatrists will determine if he needs to stay for further treatment. 

“The judge has to find based on some evidence that the defendant meets the statutory requirements,” said Bizon. “In this case, there was a forensic report from a doctor. The forensic center will make that determination. I have never seen anyone released after 60 days. Even when he is released, he must be under supervision for at least five years after release.”

Corsetti was charged with assault with intent to murder, which carries a maximum sentence of life in prison, and two felonies of assault with intent to commit great bodily harm less than murder, each of which are punishable by up to 10 years. 

Stabbing victim Patrick Peereenboom of Pontiac, Michigan, who was 30 years old at the time, was in an intensive care unit. Peereenboom sustained a stab wound near his heart where the knife hit a major artery and a stab wound to one of his lungs. Peereenboom was being called a hero, because he was trying to deescalate the dangerous situation involving strangers.

Corsetti was arrested by Michigan State Police troopers following the stabbing at the campground in the early morning hours of June 20, 2021. A 33-year-old woman and a 39-year-old man were identified as victims but were not stabbed or hospitalized.

Corsetti underwent a psychiatric exam at a state forensic center and was found “competent and criminally responsible,” said Bizon. However, the defense requested an independent evaluation.

Police were called to the scene located in the 3200 block of Winston Road at 1:30 a.m. There was a “gathering of people” at the campground, said Michigan State Police Sgt. Dan Thomas.

The campground is the site of the Lakes of Fire event, which normally occurs the third weekend in June. However, it was canceled in 2020 and 2021 due to COVID-19. The gathering that took place that weekend was not sponsored by Lakes of Fire, which is an official Burning Man event. 

“The Center for Forensic Psychiatry is a 272-bed psychiatric hospital that provides diagnostic services to the criminal justice system and psychiatric treatment for criminal defendants adjudicated incompetent to stand trial or acquitted by not guilty by reason of insanity,” states the facility’s web site.
