WA Police are turning to true crime podcast enthusiasts in an effort to break cold case homicides, some of which have remained unsolved for more than 40 years.

Hosted by veteran crime reporter Neil Poh, the six-episode Cold Case Western Australia series was commissioned as a modern way of prompting anyone with vital information on unsolved murders to come forward.

Each episode is roughly 30 minutes and includes in-depth interviews with detectives investigating the cases, and with family members of the victims.

The series debuts with the confronting case of 19-year-old Felicia Wilson (pictured) who was brutally slain with a 27-kilo limestone rock near her Kwinana workplace in 1979.
