OMAHA, Neb. — An Omaha police detective has testified that old files on a former Indiana doctor led to his becoming a suspect in the killings of four people with ties to an Omaha medical school.

The Omaha World-Herald says ( ) Detective Derek Mois testified Friday in the murder trial of Anthony Garcia. Mois said the Creighton University School of Medicine files detailed Garcia’s problems with school faculty like Dr. Roger Brumback, who was killed along with his wife in 2013, as well as with Dr. William Hunter, whose 11-year-old son and housekeeper were stabbed to death in 2008.

Prosecutors say Garcia was motivated by lingering rage over being fired from the school’s residency program in 2001.

Mois said further investigation turned up cellphone and credit card records that put Garcia near Omaha the day the Brumbacks were killed.
