HIALEAH, Fla. (AP) - Authorities say a South Florida police officer shot and killed a man armed with a flare gun.
    
Hialeah Police spokesman Carl Zogby tells The Miami Herald that police responded to a call Saturday afternoon about a domestic dispute involving 48-year-old Luis Enrique Nunez and his wife.
    
Zogby says neighbors called to report a man "running around the building with guns in the hallway."
    
Zogby says officers weren't able to calm down Nunez.
    
Both Nunez and the officers fired their weapons, but Zogby says it's not clear who fired first.
    
One officer suffered an injury to his finger, but it wasn't clear what caused the injury.
    
Nunez's sister says he had a history of substance abuse. She says police prevented her from approaching her brother to try to calm him down.
