The Hour Delia Adriano Vanished: A Cold Case in Oakville
September 26, 1982. Oakville, Ontario.
Delia Adriano was twenty-five, engaged to be married, and just days from her birthday. Dropped off by her fiancé at 9:30 PM, she took the few steps toward her family's door.
She never made it inside.
What happened in the crucial missing hour that followed?
Around 10:30 PM, witnesses report a frantic scene less than a kilometer away: a petite woman matching Delia's description was being forced into a dark, sub-compact car. An intense argument was heard inside the vehicle before it sped away, headlights off, leaving Delia's purse behind in the dark.
Six weeks later, a gruesome discovery: Delia’s body, naked and abandoned in a Milton woodland known as a “Lover's Lane.”
For over forty years, the police have had no answers. They cleared her fiancé, but a detective and Delia's own sister share a chilling conviction: Delia knew her killer.
Was it a stalker, a spurned co-worker, or an obsessive ex-partner, comfortable enough to approach her during that critical hour?
Or did Delia fall victim to a much darker force?
The killer is still out there. The case is still open.
Do you have information about Delia Adriano's murder? Contact police, Crime Stoppers, or Nicoll Investigations.
Because every case deserves answers—and every victim deserves justice.

THE GIRL IN THE BOILER ROOM: The Murder of Andrea Atkinson
A Toronto nightmare, a shocking betrayal, and a mother's decades-long fight for justice.
In October 1990, six-year-old Andrea Atkinson left her Toronto apartment to play. Just hours later, she was gone. Ten agonizing days of frantic searching ended in terror when her body was found in the most unthinkable place: the boiler room of her own building. She had been sexually assaulted and murdered.
The killer was no stranger. It was John Carlos Terceira, the building's 18-year-old caretaker—a familiar face who shattered a community’s trust. Convicted through groundbreaking forensic evidence, Terceira was sentenced to life.
But for Andrea's mother, Ruth Windebank, the battle for justice was just beginning. For over three decades, she has stood as a relentless advocate, ensuring her daughter's killer remains behind bars.Now, revisit the chilling case that defined a generation. Explore the meticulous investigation, the cutting-edge science that secured a conviction, and the ongoing fight against a killer's attempts at freedom.
Join us as we uncover the full, haunting story of Andrea Atkinson.
Because every case deserves answers—and every victim deserves justice.

Midnight on King Street - Available Now!
A Mick & Mack New Year’s Caper
New Year’s Eve, 1950s Toronto.
Snow drifts along King Street. Fireworks wait their turn. And inside the Royal York Hotel, a perfectly ordinary briefcase sparks extraordinary suspicion.
When detectives Mick McCathie and Archie “Mack” MacNeely are assigned light duty at a glittering New Year’s party, the last thing they expect is a room full of nervous glances, whispered theories, and one misplaced object that sends half the city into quiet panic.
Is it mob money? Blackmail? State secrets?
Or something far more dangerous… like sandwiches?
Midnight on King Street is a light-hearted Mick & Mack mystery — a celebration of postwar Toronto, human embarrassment, and the truth that not every mystery ends in blood. Sometimes, it ends at a diner, just after midnight.
🥂 A Whodunnit Wednesday New Year’s special.
