The trial of a District man charged in the 2011 death of his socialite wife in their Georgetown home may not begin until December or even March — months after the October date the judge overseeing the proceedings had hoped for.

D.C. Superior Court Judge Russell F. Canan had pressed prosecutors and attorneys for Albrecht Gero Muth to prepare for an Oct. 9 trial. But doctors at the District’s St. Elizabeths Hospital continue to request more time to evaluate Muth’s mental health and establish his suitability for trial and, at a Thursday hearing, Canan pushed back that date.

Another hearing was scheduled for early September. At that meeting, Canan may rule on whether to set a new trial date of Dec. 3 or push the trial back to March 25.

Muth, 48, has been charged with first-degree murder in the Aug. 12, 2011 fatal beating of Viola Drath, 91.
