The Poisoned Heiress Mystery: Who Killed Patsy Wright? | Signal 51 Chronicles Case 4 Pt. 2

The mystery of the Poisoned Heiress continues — and the suspect list gets even darker.
In the final episode of the Patsy Wright case, hosts John Henry and Jake White return to one of the most baffling unsolved murders in Texas true crime history. Patsy Bolton Wright — a wealthy Dallas heiress and co-owner of the Palace of Wax Museum empire — was found dead in her Arlington home in October 1987 after ingesting NyQuil laced with strychnine, a rare and highly restricted poison.
What initially looked like a mysterious medical emergency quickly turned into a homicide investigation involving family inheritance disputes, suspicious business dealings, stalkers, and possible financial motives.
In Part 1 we explored Patsy Wright’s life, relationships, and the shocking discovery of poison in her medicine bottle.
In Part 2, the investigation turns toward the people closest to her — including family members, former husbands, and business associates who may have had motives worth millions.
The case becomes even more complicated when investigators uncover:
• A $500,000 life insurance agreement between Patsy and her sister tied to ownership of the Wax Museum business
• A looming board meeting that could change who controlled the museum empire
• Suspicious actions by brother-in-law Steve Horning, the man who discovered Patsy’s body
• Conflicting accounts about plates found beside Patsy’s bed, suggesting she may have had a visitor
• Questions about who had access to the poisoned NyQuil bottle
• A strange connection to another mysterious death involving a Wax Museum employee
• The suspicious timing of a museum fire and insurance payouts
As investigators dig deeper, every lead seems to circle back to someone who knew Patsy personally — reinforcing the classic rule in homicide investigations:
The killer is almost always someone close.
More than three decades later, the Patsy Wright murder remains unsolved, leaving behind one haunting question:
