Washington: Three people, including the gunman, died in a shooting incident in the US state of Alabama, authorities said.
The gunman was wearing the uniform of the company where he was supposedly employed when he opened fire at the doors of its offices Tuesday, city police chief AC Roper told The Birmingham News.
The incident took place at a UPS facility in Birmingham, Alabama`s largest city, at 9.40 a.m.
Roper said the shooter was a white male some 40-years old, who shot himself before the police arrived on the scene.
The identities of the other two fatalities are not yet known, but both were also UPS employees.
"It is extremely troubling for the city, for the families involved. When they came to work today they had no idea it would be their last day alive on earth," Roper said.
"They were just people working at their jobs."
