A UPS truck driver enters a company

A UPS employee opened fire Tuesday morning inside one of the company's warehouses in Alabama, killing two people before committing suicide, police said, ABC News reported.
Birmingham Police Chief A.C. Roper told reporters that the gunman was wearing his uniform when he started shooting either in or near some offices inside the warehouse in an industrial area just north of the Birmingham airport. The sand-colored building sits on a hill and has UPS logos on the front and side. It has a parking lot surrounded by barbed wire.
The gunman had apparently shot himself by the time officers got inside the warehouse, Roper said.
Employees who were at the warehouse when the shooting happened were being taken to another location so that they could be interviewed by investigators and provided with counseling, Roper said.
