Deion Patterson, 24, entered the United States Coast Guard in July 2018 and was discharged him from active duty. He last served as an an electrician’s mate second class and his last known address was in Clayton County, Georgia, USA.

Patterson was receiving from the U.S. Department of Veterans Affairs but he was dissatisfied with the care, according to his mother Minyone Patterson, 50, of Jonesboro, Clayton County. On May 3, 2023, she accompanied him at Northside Hospital Medical Midtown in Midtown, Atlanta for an appointment seeking new treatment.

When doctors at Northside Hospital Medical Midtown would not give Deion the anti-anxiety drug Ativan, he became agitated, according to Minyone. At around 12:37 p.m., he allegedly opened fire in the hospital’s waiting room, fatally shooting Centers for Disease Control and Prevention employee Amy St. Pierre, 39, and injuring four other women aged 25, 39, 56 and 71.

Dr. Robert Janson is treating the four injured victims at Grady Memorial Hospital in Atlanta. One of the victims was shot in the face and required an interventional radiology procedure. 

After the shooting, Deion allegedly hijacked a white Toyota Tacoma, dumped the car in Cobb County, Georgia and fled on foot. Deputies from the Fulton County Sheriff’s Office and hundreds of other officers, who were heavily armed, were stationed at the scene and traffic was shut down in the Midtown area.

Minyone cooperated with police as they searched for Deion. Just before 8:00 p.m., he was arrested in the pool area of an apartment complex on Killarney Drive in Cobb County.

Deion was booked into the Fulton County Jail in Atlanta. He was charged with one count of murder and four counts of aggravated assault.
