Deadly Shotgun Standoff: FBI Manhunt For Double Homicide Fugitive

A fugitive drug dealer engaged in a shootout with state troopers, wounding two of them, and eluded capture after a high-speed chase, in this sneak peak from this weekend's Full Episode. Unravel the mystery alongside the FBI's greatest law enforcers and forensic scientists.

A respected dentist. A city on edge. And a trail of bodies stretching across decades. This chilling FBI investigation peels back the mask of Glennon Engelman, the St. Louis “deadly dentist” tied to car bombs, staged accidents, and cold-blooded executions for cash. From a Madison County farmhouse massacre to a body staged at a seedy motel, investigators chase a phantom who always seems one step ahead. A car bomb shatters the quiet south side, but a misfired device from months earlier reveals an unexpected link. An ex-wife’s terrified testimony opens locked doors: an alleged quarry “accident,” a drag-strip blast, and a suspicious 1958 killing that never sat right. Insurance windfalls, forged signatures, a bogus confession, and a killer’s arrogance converge as agents connect dots others missed. How did a mediocre dentist outmaneuver cops for years? What tiny forensic match finally cracks the case? And why did so many people closest to him keep paying with their lives? Watch the full story to see how investigators exposed the method behind the murders and the motive that never changes.

In May 2001, 11-year-old Leah Henry vanished just a block from her home in Houston, Texas. What started as an ordinary school day turned into a nightmare for her family and the beginning of one of the FBI’s most desperate hunts for a dangerous predator. With only a neighbor’s eyewitness account of a white hatchback, investigators feared the worst as Leah’s abductor carried her miles away.

A 727, a ransom, and a jump into the dark. What followed rewired aviation and ignited a nationwide hunt. This episode traces the real-life chase for Richard Floyd McCoy Jr., from the San Francisco ransom drop to that mysterious bump over Utah sky. Follow the search across Provo’s mud flats, the tip that changed everything, and the fingerprint and handwriting hits that cracked the case. Then the story swerves: a plaster-made .45 in a prison dental lab, a garbage truck jailbreak, a swamp pursuit, and a quiet Virginia stakeout that ends it all. Along the way, the shadow of D.B. Cooper looms large: the tie clip, the parachutes, the identical playbook, and a riverbank discovery years later that kept the legend alive. If you think you know the Cooper story, wait until you see how McCoy’s trail forced new aircraft design and left one question hanging in the air. Watch to uncover the choices, the luck, and the clues investigators still can’t shake. Watch now for the full investigation and decide for yourself.

A drifter with many faces finally had a name: Paul John Knowles. What followed pulled in multiple states, agencies, and a survivor who lived to tell investigators what he said next. From a failed roadside abduction in Palm Beach to a hostage taken from a quiet West Palm Beach home, the investigation widens with a chilling find: record albums in Macon that link Knowles to a double homicide in Marlboro, Connecticut. As alerts blanket the Southeast, a gas station sighting in Lakeland points to a blue Ford and a Florida trooper suddenly riding in the back seat. Then comes a desperate run on Georgia back roads, a shattered roadblock, and a tense search through woods and farmhouses. The final twist involves secret audio tapes, a lawyer who won’t hand them over without a court order, and a last, high‑stakes ride to recover a crucial weapon.

On October 2, 1987, a Boston police officer responding to a domestic disturbance call was fatally wounded. Local authorities launched a citywide manhunt, but were only able to find the fingerprints of the chief suspect.
