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 Episode 11 of Signal 51 Chronicles, John Henry and Jake White take you deep into one of the most chilling and perplexing true crime cases in Texas history — the 1987 strychnine poisoning of Dallas heiress Patsy Bolton Wright.

Born into wealth and legacy, Patsy Wright was the daughter of Texas oilman Tom Bolton and heir to the Palace of Wax Museum empire in Arlington, Texas. A Highland Park socialite turned cutting horse competitor, she was living between two worlds — high society galas and dusty rodeo arenas — when her life ended violently in the early morning hours of October 22, 1987.

Her final words:
“I’ve taken some NyQuil and something’s really, really wrong.”

On July 5, 2019, in the small lakeside community of Lake Bridgeport, Texas, Chasen and Helen Capehart woke up to the smell of burning plastic.

What they didn’t know was that their neighbor, Lauren Whitener, had been stabbed 18 times inside the adjoining duplex — and her home was set on fire.

In this gripping interview, the Capeharts recount what they heard on the night of July 4th… the arguments between duplexes… the moment they called the volunteer fire department… and what unfolded in their front yard as investigators worked the scene.
