DETROIT – A preliminary exam date has been scheduled for Mario Green, who is accused of killing his ex-wife at Henry Ford Hospital, and Anthony Barnett, Green’s alleged accomplice.
A preliminary exam is a legal hearing to determine if there’s probable cause to believe a felony was committed.
Both are set to appear in the 36th District Court on Nov. 6, 2025, at 11:30 a.m.
Green, 53, of Detroit, is accused of fatally shooting Latricia Green Brown, 40, on Aug. 22. Green allegedly entered Henry Ford Hospital on W Grand Boulevard with a gun at 9:45 a.m.
He reportedly went to Brown’s office, which was located in the basement of the hospital, and shot her, killing her.
The Wayne County Medical Examiner determined that Brown’s cause of death was a close-range gunshot wound.
Green then left the scene in a Dodge Charger, heading north on the Lodge Freeway.
He was later arrested just after 3:00 a.m. on Aug. 23 on Detroit’s east side.
Green was charged with first-degree premeditated murder, discharge of a firearm in a building causing death, aggravated stalking, possession of a firearm by a prohibited person, and four counts of felony firearm.
Barnett, 54, of Detroit, was also charged on Aug. 25 for allegedly helping Green leave the hospital after the shooting.
Barnett has been charged with accessory after the fact and lying to a police officer.
The 54-year-old man was arraigned in 36th District Court and received a $100,000 cash bond with a GPS tether and a curfew of 9 p.m. to 6 a.m.
During the probable cause hearing on Sept. 4, Barnett’s lawyers requested a reduction in his bond.
A probable cause hearing is a court proceeding that determines if there is sufficient evidence to justify proceeding with a felony criminal case to trial.
The court denied this request, citing concerns about flight risk and public safety.
