Ahead of the second episode, the fan said on Reddit: “There are multiple photos that indicate Jo replaces as acting superintendent.
“In the S6 EP2 trailer, we see Jo, Kate and Chris find a body with a very concerned looking face as the pathologist looks at it.
“Could this be Buckells and Jo killed him so she can take official control of the investigation?”
One fan responded: “I b***** hope so mate because the theories about him on Facebook are doing my nut in.”
Others are not convinced Davidson would hurt Buckells, but they hope the detective gets his comeuppance soon.
