The postal carrier accused of killing his supervisor and the Dublin postmaster will be prosecuted in federal court rather than state court, prosecutors announced Friday.

Deshaune K. Stewart, 24, is charged with fatally shooting his supervisor, Lance Herrera-Dempsey, 52, at 4:25 a.m. Dec. 23 at the U.S. Post Office on Emerald Parkway and killing Dublin Postmaster Ginger Ballard, 53, outside her Northwest Side apartment nearly three hours later by throwing her to the ground, crushing her skull. Police said Stewart been facing unspecified discipline at work.

He had been charged with the murders in both state and federal courts, but U.S. Attorney Ben Glassman of the Southern District of Ohio and Franklin County Prosecutor Ron O’Brien issued a statement saying that “justice would be best served if the case proceeded in federal court.”
