Roger, Mary Brumback Murder: Killings of Creighton Univ. professor and wife may be linked to cold case, police say

(CBS/AP) OMAHA, Neb. - Omaha cold case investigators are looking for links between the murders this week of a Creighton University professor and his wife, and the unsolved 2008 slayings of an 11-year-old boy and his family housekeeper.

Professor Dr. Roger Brumback and his wife Mary were found dead in their west-central Omaha home Tuesday. Their bodies were discovered by a piano mover who arrived and found the door of the home slightly ajar.

Roger Brumback worked with Drs. William and Claire Hunter at Creighton's medical school. Their son, Thomas Hunter, and their housekeeper, 57-year-old Shirlee Sherman, were stabbed to death at the Hunters' home on March 13, 2008.

Police have not said how Roger and Mary Brumback were killed.

No arrests have been reported in either case.

Police won't say whether they found any links, other than the professional relationships between Roger Brumback and the Hunters.

According to CBS Pittsburgh, the Brumbacks were getting ready to retire and planned to relocate from Omaha to West Virginia next month. The station says Roger Brumback was from Monroeville, Pa., a PIttsburgh suburb.
