(CNN) -- There is a $25,000 reward for information leading to the arrest and conviction of whoever fatally shot two female postal workers Monday morning in a western Tennessee post office, federal postal authorities said.
The incident in the town of Henning, about 50 miles northeast of Memphis, was reported shortly before 9 a.m. (10 a.m. ET) in a 911 call to the Lauderdale County Sheriff's Department, said District Attorney Mike Dunavant., who would not divulge who made the call.
About five people typically work in the post office at any given time, though Beth Barnett, the U.S. Postal Service's manager of communications, said she did not know how many were on duty at the time of the shooting.
Hours after the shootings, neither she nor Dunavant reported much new information. He would not identify the victims of what he called "disturbing violence," pending notification of their families.
"We're not releasing any other information pending further investigation and notification of family members," Barnett told reporters.
