Episode 155: Dinah Peterson | The Backyard Murder

Located in the northwest corner of King County in Washington State, Richmond Beach was a neighborhood in the city of Shoreline.  The driftwood scattered beaches of the Richmond Beach Saltwater Park created that quintessential northwest waterscape. In the 1970s, when the case took place, Shoreline was a world away from the hustle and bustle of Seattle, located just 35 miles south. It was a tight night community where everyone knew everyone and the residents of the town slept with their windows open allowing the cool breeze from the Puget sound to wash over them as they slept. 

But on Valentine’s Day 1975 the coastal community would be shaken to its core when a teenage girl is murdered just feet from the safety of her house.
