The shooting happened Tuesday afternoon on a USPS carrier annex.
Two US Postal Service employees died after being shot in the Memphis area, authorities said.
The alleged shooter, who was also a USPS employee, died of gunshot wounds, FBI spokeswoman Memphis Lisa-Anne Culp said during a demonstration on Tuesday.
The shooting happened Tuesday afternoon at the East Lamar Carrier Annex, an area with no buyers to sell. Around 2:50 pm local time, the Memphis Police Department said it had secured the area and there was no threat.
A witness told Memphis ABC affiliated WATN saw people fleeing saying the guns had been fired.
USPS is working with the FBI, Memphis Police department and the Bureau of Alcohol, Tobacco, firearms and explosives in the investigation, Postal Inspector Susan Link told reporters.
USPS and FBI spokespersons did not share any information about the shooting, including the names of the injured or suspected.
“The Postal Service is saddened by the events that took place today in Memphis,” said a USPS spokesman. “Our thoughts are with family members, friends and colleagues of the people affected. The Post Office will be providing resources to all staff at the East Lamar Carrier Annex in the coming days and weeks.”
This is the second-highest job experience in the Memphis region in recent weeks. Last month, one person was killed and 18 others were injured in a shooting at a Kroger store in Collierville. A suspected gunman, Kroger’s third-party dealer, died of a gunshot wound, police said.
