Teen Witnesses, a Lost Wrench, and the Nanaimo Harbour Murder of Mark Hanley

Water hides what killers hope to keep buried. In Nanaimo Harbour, it nearly does. A 13-year-old walks into the RCMP detachment with a story that redraws the map of a quiet marina night: a homeless man named Mark Hanley, a 30-foot dive boat, and a suspect, Stephen Bosch. As forensic teams uncover blood spatter and a rushed cleanup, security footage, late-night dock sightings, and two teen reenactments begin to align. But one detail threatens to upend everything: a text message that may never have existed. Meanwhile, divers scour the harbour for a two-foot wrench that could change the case—and never surface with it. Follow investigators as they sift conflicting teen accounts, a vanishing weapon, and surveillance gaps to build a case that pressures the suspect in the interview room. What really happened inside that wheelhouse, and how far can the truth travel without the proof sunk below? Watch the full episode of Dark Waters of Crime to see how the case turns. #TrueCrime #Nanaimo #RCMP #MarkHanley #StephenBosch #CrimeDocumentary #ColdWaterCases
