In Case 3 of Signal 51 Chronicles, John Henry and retired sergeant Jake White travel to Lake Bridgeport, Texas, where a quiet Fourth of July morning turned into a homicide that still haunts Wise County.

On July 5, 2019, firefighters forced entry into a dead-bolted duplex filled with smoke. Inside, they found 32-year-old Army veteran, nurse, and single mother Lauren Whitener lying on a burned mattress—stabbed repeatedly, with evidence suggesting the fire was set after she was already dead.

What followed was a tangled investigation marked by unusual evidence, complicated relationships, a possible “throuple,” removed smoke detectors, black latex gloves found hundreds of yards away, and a nine-hour interrogation involving a Texas Ranger and a DOJ polygrapher. Despite it all, no arrest has ever been made.

This episode walks step-by-step through the early hours of the crime, the neighbors’ statements, the evidence collected—and the evidence that raises more questions than answers.
