CLAYTON — A former St. Louis County police officer accused of firing several shots at a Kirkwood elementary school’s Halloween event was indicted Wednesday by a grand jury.
The indictment moves the case forward against Matthew McCulloch, 39, who now faces six counts of child endangerment, one count of making a terrorist threat and several weapons offenses.
McCulloch was originally charged last month, but the indictment added two more child endangerment counts because additional victims agreed to testify, according to prosecutors.Â
St. Louis County Prosecuting Attorney Wesley Bell assigned the case to his office's Conviction and Incident Review Unit, an independent unit that handles cases involving police officers and other public figures.Â

On Oct. 15, McCulloch attended a Tillman Elementary School trunk-or-treat event full of hundreds of children and parents in the parking lot of North Kirkwood Middle School, according to court documents.Â

Police said McCulloch approached several people and made death threats. Someone eventually shoved McCulloch after he threatened the person and their wife, an affidavit said.
He then fell to the pavement and, while surrounded by “hundreds of children,†stood up and pulled up his shirt to display a handgun and badge, the affidavit said.
McCulloch then fired into the air at least a dozen times while shouting again that everyone would die, police said.
Several people tackled McCulloch and took his gun from him, according to court documents.
No one was injured.
McCulloch’s family has held leadership positions for decades in local law enforcement. His father, Bob McCulloch, served 28 years as St. Louis County’s elected prosecutor before losing his reelection bid in 2018. His uncle, Joseph McCulloch, is a retired St. Louis city police officer and was appointed earlier this year as the top prosecutor in St. Charles County. His grandfather, Paul McCulloch, was also a police officer and was killed while on duty in a shootout in 1964.
A judge set McCulloch's bail at $500,000 cash-only with a condition that he undergo a mental health evaluation. His attorneys wrote in court documents that he "is in urgent need of mental evaluation and treatment."
McCulloch was no longer employed with St. Louis County police within days of the trunk-or-treat event, according to the department.
