Dive deep into the darkness of the Las Vegas massacre in this week’s episode of Dark Investigations. We unpack the deadliest mass shooting in modern U.S. history—step onto the Mandalay Bay concert grounds as gunfire erupts, hear harrowing dispatch calls and survivor testimonies, and trace the baffling timeline that left investigators and the public scrambling for answers.

Then, peel back the layers of official reports to examine the conspiracy theories that refuse to die: whispers of a second shooter, allegations of a Saudi royal hit, and claims of a CIA-backed arms sting.

 Across seven riveting acts, Bill Dunlap weighs each theory against the cold, hard facts—and exposes the power of silence when the truth is too dangerous to share. Tune in for a journey through chaos, intrigue, and the shadows that linger long after the headlines fade.

In this debut episode of Dark: True Crime Investigations, we unravel the mysterious death of investigative journalist Danny Casolaro, whose relentless pursuit of a shadowy conspiracy he called "The Octopus" led him into a web of danger and deceit. From uncovering corruption in the Inslaw PROMIS software scandal to exposing alleged connections between government operatives, organized crime, and international espionage, Casolaro believed he was on the verge of exposing a vast, interconnected network of power.

But before he could share his findings, Danny was found dead in a hotel bathtub under suspicious circumstances, his notes and manuscript missing. Officially ruled a suicide, his death raised more questions than answers. Was he silenced for getting too close to the truth? Or was the pressure of his investigation too much to bear?

Join us as we delve into the facts of Casolaro’s case, explore the enigmatic “Octopus” conspiracy, and examine the chilling aftermath of his untimely demise. A story of ambition, intrigue, and the perilous cost of chasing the truth, this episode will leave you questioning how far the reach of secrecy and corruption truly extends.
