This true crime documentary series sheds new light on some of the most callous and violent crimes in recent years by examining What The Killer Did Next…

Season 1 is fronted by Life on Mars and Outcast star Philip Glenister and supported by compelling testimonies from serious crime detectives, defence lawyers and expert criminologists and psychologists. What The Killer Did Next provides a step change in true-crime storytelling by focusing on the behaviour of killers in the immediate aftermath of a murder to unpick their mind-set and understand their motive

Every episode hones in on the eeriest and most insightful part of a murder story; the time between the murder of the victim and the capture of the killer, when the killer remains at large to act freely and the authorities are in a race to catch them.

By focusing on this very specific window of a crime, we’re able to centre on the question we all ask when someone kills — what kind of person did this? And it’s the killer’s actions in the immediate aftermath that give us an insight into the answer.

The average audience share for Season 1 was 2.5x times higher than the channel's benchmark.

Season 2 returned to Sky Crime in November 2022.
