6News has obtained a copy of the coroner's report, which lists the cause of death for Dr. Roger and Mary Brumback of Omaha.
According to the coroner's report, 65-year-old Mary Brumback was stabbed to death and 65-year-old Roger Brumback died of a gunshot wound. Both were found dead in their home near 114th and Shirley on May 14.
Police have been trying to determine if this double-homicide is related to another double-homicide five years ago. Eleven-year-old Thomas Hunter and his family's housekeeper Shirlee Sherman were found dead inside the Hunter home near North 54th and Davenport streets on March 13, 2008. That case remains unsolved.
Both sets of murders have a connection to the Creighton Pathology Department where Thomas' father was a colleague of Dr. Brumback.
No arrests have been made in either case.
