John Kim, the show’s executive producer, said they had never filmed in Oklahoma before, but that Tulsa had been under consideration for a while.

“(We) were impressed with the quality and the professionalism of the investigators and the whole department,” Kim said. “Their homicide unit’s effectiveness is reflected in their high closure rate of cases, so Tulsa PD was always on our radar as a department to feature.”

Roberson said the department did not take the show’s request lightly, and questioned the producers at length to ensure the investigation that will be covered would not be hindered.

“We asked (the producers) every question under the sun about how their presence could possibly damage our scenes, and we couldn’t find one,” Roberson said. “Their cameramen and camerawomen and producers know if they’re told ‘too much,’ they have to go. We’ve set boundaries for them and they know that. They’re experienced; they know what they’re doing.”

Residents who are near a homicide scene will be asked whether they will agree to be filmed, according to the release.
