The Beast of Birkenhead: 7. The Profiler

A Geographical Profiler looks at the two locations connected to Diane Sindall’s murder. It’s suggested that Diane’s killer was local and may have struck before.

As new testimony suggests Diane may not have been attacked in the alleyway and emerging accounts name a local figure, the investigation edges closer to a new suspect.
