On August 12, 1998, 81-year-old William Carroll of 1619 N. Boston in Tulsa answered a knock at his door and was stabbed twice in the chest by an unknown assailant. He was taken to a local hospital and died of his injuries on August 20, 1998, after eight days in care.

Investigators initially considered robbery a possible motive, but few clues were left at the scene. The Tulsa Police Department was unable to identify suspects or make arrests, and the investigation eventually grew cold. The case remains an open cold case, with the perpetrator or perpetrators still unidentified.

If anyone has information about the August 12, 1998 attack or remembers unusual activity in that neighborhood around that time, please come forward to help bring closure to the family of William Carroll.
