What is it like to survive an encounter with a serial killer—and then learn what he did to the men who came after you?
In this episode of UNMARKED Case Notes, I sit down with Mark Henderson, a survivor of Toronto serial killer Bruce McArthur.

Mark takes us inside his encounter with McArthur: how they met, what happened between them, the details that have stayed with him, and what it was like to later discover that McArthur had murdered eight men.

We also talk about the Bruce McArthur investigation, the warning signs that were missed, and what Mark’s experience reveals about the man behind one of Canada’s most notorious serial murder cases.

This is a firsthand account of Bruce McArthur from someone who encountered him—and survived.

A deeply polarizing story is unfolding in Massachusetts, where a young mother is accused of killing her three children inside their family home. As the case moves forward, it has sparked fierce debate over mental health, motherhood, responsibility—and whether the devastating events of that day could have been prevented in the days leading up to the tragedy..

In this Friday edition of UNMARKED, producer Jon Nadeau joins me to break down the final arguments in the Lindsey Clancy case and what we know about the insanity defense.

Then we get into your questions: How did Charles McArthur hide in plain sight for so long, why do siblings of serial killers often have normal lives, and which serial killer would James would most like to sit.

How did Bruce McArthur murder eight men in Toronto’s Gay Village while hiding in plain sight?

In this episode of UNMARKED, James Buddy Day returns to Toronto to retrace the footsteps of one of Canada’s most notorious serial killers—speaking with people who knew McArthur, walking the streets where he found his victims, and revisiting the properties where he concealed their remains.

Drawing from Buddy’s original investigation for the Canadian Screen Award-winning documentary Catching a Serial Killer: Bruce McArthur, we examine McArthur’s double life, his psychology and evolving fantasies, the murders of eight men, and the extraordinary opportunities police had to identify him before his eventual arrest.

Why did investigators fail to stop McArthur despite witnesses, previous arrests, survivors, and his name appearing in an earlier investigation? And what does his case reveal about the vulnerable populations serial killers choose to target?
