🕵️♀️ Mary Morgan Pewitt Murder — Comanche, Oklahoma (1988) | Case Summary
Who:
Mary Morgan Pewitt, age 25, was a young mother of two daughters and a resident of Comanche, Oklahoma. She had been married three times by her mid-20s and was known for her strong personality and sometimes turbulent relationships.
When & Where:
On June 4, 1988, Mary was discovered dead inside her home in Comanche, Stephens County, Oklahoma.
What Happened:
Mary was found brutally stabbed more than 30 times — primarily in the chest and neck — indicating an extremely violent attack. The injury pattern suggested defensive wounds, meaning she likely fought back against her assailant.
Discovery of the Body:
Her mother and two young daughters (ages 6 and 7) discovered her in the early morning. One of the daughters looked through a bedroom window and saw her mother covered in blood.
Last Known Movements:
The night before, Mary worked closing shift at Harold’s Club, the only bar in town. She reportedly dropped receipts off for the bar owner, returned home late at night, and was last seen alive around 12:45 a.m. with a friend. What occurred between then and the morning remains unknown.
Investigation & Leads:
– The murder was initially handled by Comanche Police Department, then the Stephens County Sheriff’s Office, and eventually taken over by the Oklahoma State Bureau of Investigation (OSBI) cold case unit.
– Despite multiple suspects being considered — including men from past relationships and acquaintances — no arrests have ever been made.
– The brutal nature of the crime and lack of solid evidence left the case unsolved. The OSBI even featured Mary in their “cold case playing cards” deck to solicit information from inmates.
Family & Legacy:
Mary’s daughters grew up without their mother and have been outspoken in seeking justice and renewed investigative attention. The community continues to remember her case as Comanche’s only unsolved homicide from that era.
Reward & Public Appeal:
The OSBI at times offered rewards (up to $10,000) for information leading to an arrest, emphasizing that it’s never too late to come forward with tips.
