OMAHA, Neb. (AP) — Trial for a former doctor accused of killing four people with ties to an Omaha medical school has been rescheduled for later this year.

The trial for Anthony Garcia is now set to begin Sept. 14. His trial had been set for Feb. 17. In December, Garcia waived his right to a speedy trial.

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.

Authorities contend that Garcia was motivated by revenge for being fired from Creighton’s pathology department in 2001.
