Police say naked Ohio postal worker fatally attacked supervisors

DeShaune Stewert is accused of killing his supervisor, Lance Herrera-Demsey, and Dublin postmaster Ginger Ballard.

"There had been some type of investigation into his misconduct and it had culminated into possibly him being terminated, and this was apparently the reason his response was very violent," said Sgt. Dave Sicilian with the Columbus Police Department.

Investigators believe Stewert shot and killed Herrera-Demsey first inside the post office.

Court documents state that another employee saw Stewert standing completely naked and pointing a gun at Herrera-Demsey.

That employee then said that he saw Stewert shoot Herrera-Demsey once while standing and another time when he fell to the ground. Then he says Stewert left.

"We received a call here at this apartment complex, where there was a male who was apparently causing alarm to a resident," said Sgt. Sicilian. Police say that's where they found Stewert and arrested him. After they searched the area, they found Ballard dead.

"It all occurred outside in the parking lot," said Sicilian.

Court documents state Ballard was thrown on the ground, where she hit her head and died instantly from blunt force trauma.

The local post office has temporarily suspended all delivery and mail collection operations.

A spokesperson from the post office released a statement that read, "We would like to apologize for any inconvenience and thank the Dublin community for their understanding and support. Our thoughts remain with the victims of this senseless act of violence and their families.

Stewert has been charged with aggravated murder for both killings.
