In March 2008, Omaha was rocked by the grisly killing of an 11-year-old King Science student and his family’s house cleaner, a 57-year-old grandmother.
Over the years, police investigated various leads in the deaths of Thomas Hunter and Shirlee Sherman, the son and housekeeper of the then-director of Creighton University's pathology department's residency program, but arrested no one. In 2013 police got a break in the case, though not the kind they hope for. Someone killed two more people associated with the Creighton pathology department: Mary Brumback and her husband, Dr. Roger Brumback, a colleague of Thomas Hunter’s father.
Omaha Police Chief Todd Schmaderer formed a task force to look into the four deaths. Two months later, the chief announced that Omaha police had arrested a doctor in connection with Omaha’s four most high-profile homicides in recent years.
