Robert Eugene Singleton Jr. was 27 and working in construction when he was shot and killed in Tulsa on February 16, 2015. The shooting followed a domestic dispute tied to relationships: Singleton had spent the night at an east Tulsa apartment with his son and the child’s mother, who had recently ended a two-year, on-and-off relationship with another man, Cameron Jerel Hendrick.

The next morning Hendrick went to the apartment after learning Singleton had been there. An altercation occurred in the complex courtyard and Singleton was fatally shot. An arrest was made and charges were filed in connection with the killing.

Did anyone in east Tulsa at the time see or hear anything in the courtyard that morning who hasn’t yet spoken to investigators?
