OMAHA, Neb. (AP) — A county judge in Omaha has removed himself from a murder trial involving a former doctor accused of killing four people with ties to an Omaha medical school.

Douglas County District Judge Duane Dougherty removed himself from Anthony Garcia’s murder trial due to health reasons during a Wednesday afternoon court hearing.

Judge Gary Randall will now be assigned to the case.

Garcia is charged with first-degree murder in the 2008 deaths of Thomas Hunter, the 11-year-old son of Creighton University pathologist William Hunter, and Shirlee Sherman, the family’s housekeeper, as well as the May 2013 deaths of Creighton pathologist Roger Brumback and his wife, Mary.

His trial was previously set to begin on April 4 but will likely be delayed.
