COLUMBUS, Ohio — Special agents with the U.S. attorney's office will be heading to Columbus this week to investigate the case of a U.S. postal employee charged with killing two of his supervisors.
Deshaune Stewart, 24, was admitted to Twin Valley Behavioral Hospital Christmas Day.
On Saturday, police say he tracked postal inspector Ginger Ballard down at her apartment and threw her to the ground. The blunt trauma to her head killed her.
Ballard's death came three hours after police said Stewart walked into the Dublin post office fully naked and shot and killed his supervisor Lance Herrera-Dempsey.
The nine other employees in the facility ran and called 911. Those calls were released Tuesday. In one, an employee is heard telling dispatchers the shooter was one of their mail carriers.
"Yeah. He came in naked with a gun and he shot one of our supervisors," said the 911 caller.
Police said both Herrera-Dempsey and Ballard were investigating Stewart for alleged workplace misconduct. That investigation could have led to him being fired.
Police reports also indicate Stewart left the home that he shared with his wife two weeks ago. Reports state Stewart dropped off his two-year-old daughter with his sister one night before the killings.
