According to the paper today, the pizza guy worked for Pizza Hut. Their corporate policy is to not allow employees to carry weapons, but leave many things to the discretion of individual store owners. This policy is one of them. Though it was stated that the local store followed the corporate example and the employees sign a document explaining the policy, the store employees declined to comment on what action would be taken in this case.
BTW, the kids reported the incident to the police first and said they were the victims of a drive-by. The pizza guy reported a little later the robbery attempt and stated that he had shot two of them. His story seemed to be the more credible of the two, but so far, no charges have been filed against any of the parties involved.
It will be up to the Taylor County prosecuters to decide if the pizza guy will be charged for unlawfully carrying.
