(Associated Press) Police say a clerk at a Las Vegas Dairy Queen shot and killed a sword-wielding, masked man who tried to rob the restaurant.
Detectives say the suspect was shot twice and was lying just outside the doors when officers arrived around 12:15 p.m. Sunday.
The suspect died at a hospital.
Authorities say the shooting appears to have been in self-defense but that detectives were investigating whether the gun used was properly registered.
They say only two employees and no customers were present at the time of the shooting.
