PANAMA CITY, Fla. (AP) - A machete-wielding man was shot and killed by a Panama City police officer.

Police say the man was holding a machete and screaming in the middle of a street when officers arrived Sunday. They asked 40-year-old Clifton Delaine McKinney to put down the machete and surrender, but he refused.

The Panama City News Herald quoted neighbor Kathy Simmons saying it looked like McKinney planned to surrender until he charged the officers. Simmons says the man was swinging the machete wildly.

Panama City Police Chief John Van Etten says officers used a stun gun several times on McKinney, but it didn't have the effect it normally does. An officer then shot the man.

An investigation continues.
