OMAHA, Neb. (AP) — A jury has been empaneled in the case of former doctor Anthony Garcia, accused of killing four people with ties to an Omaha medical school.

Garcia is accused in the March 2008 slayings of 11-year-old Thomas Hunter and his family’s housekeeper, Shirlee Sherman, as well as the May 2013 killings of Dr. Roger Brumback and his wife. The boy was the son of Dr. William Hunter, who worked with Roger Brumback at the Creighton University School of Medicine’s pathology department. Prosecutors say Garcia was seeking revenge against the doctors over their firing him from the pathology residency program in 2001.

It took five days to whittle down a jury pool of more than 100 to six men and six women. The four alternates consist of three men and one woman.
