(CNN) -- Three people were dead Tuesday morning after a shooting at a UPS facility in Inglenook, Alabama, said Capt. Jerry Wiley of the Birmingham Police Department.
A Birmingham police officer responding to a report of an active shooter found three people dead, including the gunman from an apparent self-inflicted gunshot wound.
Police said there were no other suspects. Wiley said the motive was not known.
According to CNN affiliate WBRC, the shooter was a recently-fired former UPS employee. He was terminated Sunday, the affiliate said, and wore his UPS uniform when he returned to the facility Tuesday.
Citing a police lieutenant, the affiliate reported the two victims are believed to be higher-ranked employees.
The Birmingham Police Department identified the shooter as Kerry Joe Tesney, 45, of Trussville. The identity of the victims has not been released by police.
"It appears that the shooter knew exactly who he wanted to target at the time," said Birmingham police Lt. Sean Edwards, the affiliate reported.
The FBI in Birmingham had no immediate comment. An investigation is ongoing.
"Our thoughts and prayers are with the families and co-workers of those who died this morning," Alabama Gov. Robert Bentley said in a statement.
"State law enforcement resources are available and ready to assist if needed as investigators work to determine a cause in this deadly shooting," he said.
