Columbus man accused of killing 2 post office supervisors found not guilty by reason of insanity

A Columbus man charged with killing two post office supervisors in 2017 has been found not guilty by reason of insanity, according to the U.S. Attorney’s Office.

DeShaune Stewart had been indicted on two counts of murdering an officer of the United States Government.

According to court documents on December 23, three witnesses said they saw a naked man, who they identified as Stewart, shoot 52-year-old Lance Herrera-Dempsey in the post office in Dublin.

Police say Herrera-Dempsey was Stewart’s supervisor and that Stewart was under investigation by the U.S. Postal Service.

Following the post office shooting, authorities say Stewart went to an apartment complex on Bowland Place in north Columbus.
