On the evening of February 24, 2019, a family argument at a home near Southwest 35th Street and Western Avenue in southwest Oklahoma City ended with 43-year-old Shane Bonitz shot dead. Police were called just before 6 p.m.; when officers arrived they found Bonitz mortally wounded and later pronounced him dead at the scene.

Investigators treated the death as a criminal homicide, documenting the scene, collecting shell casings and interviewing neighbors who heard the disturbance and gunshots. Guinn was taken into custody the same night and initially booked on a firearms-related complaint tied to a prior felony conviction; prosecutors later filed a first-degree murder charge against him in Oklahoma County. Did anyone see or hear details from that night that could clarify what happened?
