The incident reportedly began when other shoppers confronted Scavetta for not wearing a mask inside the store. Store security video shows the suspect pushing an older man in a wheelchair through the store. The man in the wheelchair pulls a red neckerchief over his mouth in the store.
A shopper wearing a mask approached the suspect, and the unmasked man gives the shopper the middle finger before pulling a handgun from his waistband, the sheriff's office said, and reportedly threatened to kill the other shopper.
Video shows the men were about 10 feet apart and yelling obscenities at each other, when Scavetta raised his middle finger at the other shopper, who advanced at Scavetta pointing his umbrella, investigators said. Another shopper interceded and Scavetta started to walk away. The first shopper said something more to Scavetta, who pulled a gun from his waistband and pointed it at the man, whose daughter grabbed him by the hand and tried to pull him away. Scavetta said the other man had threatened him and his father and hit him in the forehead with his umbrella's tip, WFOR-TV reports.
