Myers, who says he’s a licensed security guard, was sitting in his car Wednesday to conduct “overwatch” while his son trains because “he has seen numerous crimes occur” in the parking lot, according to the probable cause statement.

The surveillance footage shows Myers approach the teens with a gun in his hand, point it directly at them and then move quickly toward them, police said. One of the boys pulls a BB gun out of his pocket, lays it on the ground and extends his arms out as if to show he has nothing in his hands, police said in the document.

“Immediately after … it is clear that he has been shot because he abruptly jerks his body away from Myers and falls to the ground,” the document says.
