Sunday morning before the worship service, a 36-year-old man from St. Charles, Missouri, entered the church and asked to speak with the pastor. Church security personnel called police to communicate their suspicions about the man and his vehicle in the church parking lot. Law enforcement responded and discovered that the vehicle had been reported stolen. During the struggle, when police attempted to restrain the man, he produced a firearm, which discharged, and he was struck. He died the next day.

• Wesley Memorial Church, High Point, North Carolina, June 28, 2026
An armed 44-year-old man wearing camouflage clothing and body armor sat in his truck in the parking lot during the morning service. An observant person called 911, and an off-duty officer working at the church immediately responded to the parking lot. Additional officers arrived, disarmed the man, and took him into custody without incident. Upon searching his truck, officers found 2 flamethrowers, 2 crossbows, 3 knives, 500+ rounds of ammunition, a CO2-powered launcher, designed to resemble a handgun, rolls of black duct tape, oxycodone pills, and a notebook containing the addresses of churches, schools, and public buildings. The man, who authorities say has experience with bombs, also had two radios with police scanners, GPS coordinates, handcuffs and keys, and a copy of the North Carolina Tactical Interoperability Guide marked public safety sensitive.
