Curtis Lee Nolen, a 50-year-old White man, was killed during a violent weekend in Oklahoma City in the late summer of 2012. His death was one of five homicides that occurred over a 48-hour span that weekend, a cluster that contributed to a yearlong rise in violent crime in the city.

Authorities treated Nolen’s case as a separate investigation and did not publicly link it to the other four killings that weekend. Specific circumstances of his death were not widely publicized at the time, and his case drew less media attention than some of the other homicides. No suspect or suspects have been publicly identified or arrested, and the murder remains unsolved.

If anyone has information about Curtis Lee Nolen, his activities that weekend, or potential leads in his case, please come forward to help his family find answers.
