Kenneth Keeling Jr., 41, was shot and killed on December 14, 2015, at the Summerfield Village Apartments, 920 E. Lindsey Street, in Norman, Oklahoma. Police found Keeling suffering from a gunshot wound shortly before 10 p.m.; he was taken to a local hospital and died from his injuries. Keeling had been outside on the balcony of his apartment, smoking, when gunfire erupted. His wife Jeannie and their daughter attempted to save him, with Jeannie performing CPR as he lost consciousness.

Investigators concluded Keeling was an innocent bystander struck during gunfire directed at another group. The investigation focused on Mathiaz Oropeza, Anthony Bing Alexander Mundell and Tevin Kyreece Martin-Hicks. By early February 2016, police had arrested 17-year-old Mathiaz Oropeza and 19-year-old Anthony Mundell on first-degree murder charges; Martin-Hicks, then 18, was sought and a reward was offered. Martin-Hicks was located and arrested in Independence, Kansas, on June 6, 2016, and later charged in Cleveland County on June 20, 2016. Court records show Martin-Hicks pleaded guilty on March 29, 2018, and a final judgment filed in April 2018 imposed a life sentence with all but the first 35 years suspended, crediting time served. Reports do not provide clear final dispositions for Oropeza and Mundell.

Did anyone in the community know Keeling or have information about the night he was killed?
