A former North Carolina police officer was arrested in Florida after authorities said he planned a mass shooting at a New Orleans music festival.

Christopher Gillum, 45, of Chapel Hill, North Carolina, was taken into custody around 6:40 p.m. Wednesday at a hotel in Destin, Florida, the Okaloosa County Sheriff’s Office said.

Authorities said Gillum was wanted for making "terroristic threats" and was believed to be traveling to a festival in New Orleans to "conduct a mass shooting."

Investigators recovered a handgun and about 200 rounds of ammunition from his hotel room.

Gillum’s family reported him missing Tuesday, telling authorities he had a history of self-harm and had made threats to harm "Black people," according to a police bulletin from Burlington, North Carolina.

Lt. Clint Lyons of the Alamance County Sheriff’s Office said Gillum left the state before authorities could initiate an involuntary commitment, adding there were no legal grounds to detain him at the time.

Earlier Wednesday, Gillum had been stopped by law enforcement in Okaloosa County but was released because he did not meet criteria for arrest or commitment, according to the bulletin.

Deputies later conducted surveillance after learning he was under investigation and arrested him once a warrant was issued from Louisiana, authorities said.

Gillum is expected to be extradited to Louisiana to face charges, the sheriff’s office said.

Authorities did not name the event, but the New Orleans Jazz & Heritage Festival — known as Jazz Fest — runs through May 3 and draws hundreds of thousands of attendees annually. Louisiana State Police said "there are no known direct threats" to any festivals in the state.

Gillum served as a sworn police officer in Chapel Hill from 2004 until his resignation in 2019, according to a town spokesperson.

He later worked as a police officer in Carolina Beach from October 2019 to October 2020, then became a detention officer with the Orange County, North Carolina, Sheriff’s Office in October 2023, leaving in July 2024.
