Police in Chesterfield County Virginia are seeking information that could lead to the arrest of whoever fired a shot into the air that struck and killed 7-year-old Brendon Mackey on July 4. According to the Richmond Times-Dispatch, the boy was walking with his father in a parking lot when he abruptly fell to the ground lifeless.

It was only after the boy was rushed to the hospital that health care workers found the bullet wound to his head. Police say that the projectile was likely fired randomly into the air by an Independence Day celebrant.

The Times reported that a nurse named Frances H. Derrer was nearby when the child was struck, but didn't notice anything out of the ordinary until she heard someone say, "He has no pulse."

Derrer and another nurse performed CPR on the boy until paramedics arrived, but to no avail.

"I just don't understand why anyone would shoot guns up in the air," Derrer told the paper.

Brendon's father said that his son was laughing before he abruptly fell to the ground. No one at the scene realized he had been shot. There was reportedly just a small amount of blood on the pavement where his head fell.

"Doctors discovered that Brendon had suffered an apparent gunshot wound to the top of his head," police said in a statement. "Police believe this wound was the result of someone shooting randomly into the air, likely from a distance, and not an intentional act. Police need the public's help to locate whoever fired the round."
