The Mysterious Disappearance of Dorothy Arnold
In December 1910, 25-year-old Dorothy Arnold, heiress to a wealthy New York perfume fortune, stepped out for a routine shopping trip on Fifth Avenue and vanished into thin air. Educated at Bryn Mawr, dreaming of a writing career, secretly involved with an older man her family despised—she left no note, no body, no clues. Her prominent family delayed police involvement for weeks, fearing scandal, while Pinkerton detectives launched a massive transatlantic hunt with unlimited funds. Theories range from elopement to botched abortion, suicide, or foul play, but over a century later, the truth remains elusive. Dive into this baffling historical cold case on Historical True Crime Tuesday.

The Silence of Beachview Avenue: The Murder of Leah Sousa
Labor Day 1990: Cumberland Beach was paradise—until murder struck. 13-year-old Leah Sousa, sexually assaulted and bludgeoned in her own backyard. Her mother Lora, left for dead in a blitz attack. Baby brother spared. No DNA, but a bloody shoeprint points to a size 10 or 9 Nike.
Suspects? Convicted killer Brian Ellson, just blocks away. Or 'Mister X,' a predator with ties to the family and other cold cases.
Retired cop Barry Ruhl says it's a serial killer hiding in plain sight. Lora's memory is gone—but justice isn't. Ontario Cold Cases: The Silence of Beachview Avenue.
Coming this Sunday January 18.

The Gravel Pit Murders of Kathy Potter and Lee Kirk
On a warm October night in 1971, two teenage girls set off for a visit that would change everything. Kathy Potter, 13, and Lee Kirk, 15, left their Toronto foster home heading for Richmond Hill. They never arrived.
Two days later, their bodies were discovered side-by-side in a Pickering gravel pit. They had been carefully placed, yet brutally strangled. The investigation that followed revealed a heartbreaking breakdown in communication by the Children’s Aid Society and a trail of forensic clues—orange paint chips, welding beads, and mysterious grey hairs—that led to more questions than answers.
Was it a biker initiation, a chance encounter with a predatory trucker, or a secret meeting at a wine party gone wrong? Join us as we re-examine the evidence, the suspects, and the cold reality of hitchhiking in the 1970s. We are keeping the memory of Kathy and Lee alive until justice is finally served.
Because every case deserves answers—and every victim deserves justice.
