Mark Staudte Wikipedia- Diane Staudte Husband Murdered

Mark Staudte died of what looked to be natural causes; however, some blamed his death on his unhealthy lifestyle.

His bandmates noticed he was acting weird, saying he was slurring his words, and his complexion appeared yellow. According to police accounts, there was a ring of blood around his mouth at the time of his death.

Five months after Mark's death, tragedy struck again when Shaun Staudte, Staudte's son, died of flu-like symptoms.

According to his postmortem report, a ring of blood was observed around his mouth, although his death was caused by past medical concerns, including a seizure disorder.

When Mark Staudte abruptly becomes ill and dies, it leaves his friends and family with unanswered questions. But, when other family members display similar symptoms, doctors must solve the mystery before it’s too late. Something’s Killing Me with @BD_Wong, Sunday at 8p ET/PT. pic.twitter.com/5CvW973Ujw

The Staudte Family Murders Story Explored By ABC

Diane Staudte claims she is innocent despite confessing to authorities that she poisoned her husband, son, and daughter with antifreeze.

In an exclusive interview with "20/20," Staudte said, "She said what she was taught to say; she's suggesting there's more to that than what people know." There is no proof that anyone other than Diane Staudte and her daughter, Rachel, was responsible for these heinous atrocities despite her denials.

Diane Staudte said she's ready to reveal the line of events that led to her life without parole nearly six years after pleading guilty to two charges of first-degree murder.

"Tiny professors," Staudte said of her children, "who all had their little special interests, but boy did they know everything about them."

Sarah Staudte, Diane Staudte's eldest daughter, was rushed to the hospital by her mother and sister Rachel Staudte.

Sarah Staudte was taken to the ICU with a brain bleed and organ failure. Doctors began to suspect poisoning while she was in the hospital.

Simultaneously, samples from Shaun Staudte's autopsy were collected, and testing revealed the presence of ethylene glycol, one of the antifreeze's essential components.

Sippy stated he tipped the Springfield Police Department after Sarah Staudte was hospitalized.

Because ethylene glycol is not a common element of standard toxicological screens and requires special testing to identify, it was overlooked at the initial autopsy.

According to interrogation audio acquired exclusively by ABC News, Diane Staudte admits to poisoning her family by putting antifreeze in her children's Coca-Cola and husband's Gatorade.

McAmis questioned her about why she didn't bring her spouse to the hospital during the interview.

She despised his guts, and I suppose she'd had enough, Staudte told detectives.

Mark Staudte Brother & Family Today 2022

There is no information about Mark Staudte's brother in the media; however, the remaining family left was Briana Staudte.

It's unclear what happened to her after Diane and Rachel were arrested. Briana, a fourth-grader and small child at the time, had yet to be poisoned by her mother or sister.

Due to her age, the girl's new name has not been revealed by news outlets. She has been placed in foster care.

Sarah Staudte lived, but the antifreeze caused serious organ and neurological damage. Her symptoms, which were initially misdiagnosed as flu-like, were subsequently shown to result from the poisoning.

Sarah has a Facebook page dedicated to the murder case, complete with a profile banner photo of her father appearing in the film Messing With Destiny. 

Sarah had the chance to read the following statement in court: she would rather be a survivor than a victim. She accepts her mother's apology for what she did to her.

But she took away my father and brother and her way of life, livelihood, and independence.

Sarah, who had been on the Dean's List during her undergraduate years, was reported by Greene County Prosecuting Attorney Dan Patterson to require "a guardian and living in an assisted living facility" due to the poison's effects on her body and mind.
