A D.C. Superior Court judge has ordered a D.C. man charged with setting his home on fire, leading to his wife’s death, sent from jail to St. Elizabeths Hospital, the city’s psychiatric facility.

Judge Anita Josey-Herring issued the directive Tuesday after court psychiatrists who examined Robert L. Proctor found him incompetent to stand trial. Proctor, 76, is charged with arson in the Feb. 13 fire of his home in the 4600 block on Fourth Street NW. Proctor’s wife Lucille, 80, died in the blaze.

Proctor, who had been hospitalized in the past for mental illness, allegedly told police after the fire that he and his wife constantly argued, that she refused to divorce him and that he believed she was having an affair.

It was unclear whether Proctor would face additional ­charges. Although authorities say Lucille Proctor died from burns and smoke inhalation, the medical examiner has not issued a homicide ruling in her death.

The judge ordered a second mental evaluation and scheduled another hearing for June 3.
