WAVY.com located the 911 caller and spoke to her. She confirmed Khalid was taking target practice using a zombie hunter airsoft gun to kill the zombies. There was also a net behind the target to catch the plastic pellets.
The caller also knew the gun wasn't real and said so, "This is not a real one, but it makes people uncomfortable. I know that it makes me (uncomfortable), as a mom, to see a boy pointing a gun," she told the 911 dispatcher.
The airsoft guns are designed to be non-lethal. Plastic pellets are used, and not copper bb's.
