Sandra Duyst: Death of a Horsewoman

An Insurance Salesman Exercises Bad Policies
(‘Murder She Wrote,’ Forensic Files)

Many online viewers have expressed amazement that Sandra Duyst stayed married to a man who tried to kill her — particularly since he did so in a way that left no other interpretation.

David Duyst attacked his wife with an ax-hammer.

But instead of blaming him, Sandra told friends and medical professionals that her cranial injuries happened as the result of a horse-related accident. As sad as the case is, there’s nothing terribly surprising about it to me.

Kids in the equation. She appears to be the victim of a profound case of resignation fueled by low self-esteem and embarrassment.

But where did the low esteem come from? For this week, I looked for some answers.

There’s no need to check on her husband’s status — as the producers noted after the show, David Duyst ended up dying in prison. But the couple left three children, so I searched for information about how Erica, Timothy, and David Duyst Jr. handled the aftermath of their mother’s death.

So let’s get started on the recap of “Murder She Wrote,” along with additional information from internet research:

Sandra Anne Bos was born on Dec. 29, 1959, in Grand Rapids, Michigan. At the age of 3, she participated in her first horse show and went on to collect numerous equestrian awards. She was also MVP of her high school volleyball team.

She and David Duyst, the son of a history teacher and a librarian, met in high school and got married after they both attended Calvin College in Grand Rapids, Michigan.

The two had grown up in the area and had lots of friends, according to Beyond the Grave: The Murder of Sandra Duyst, an ID Network show produced in 2016.

The Duysts moved to a house in Alpine Township and built a stable on the property. She specialized in raising and training quarter horses and gave riding lessons.

Blame it on Dexter. David started his career as an Amway salesman, then joined his father-in-law’s insurance company, Northwestern Mutual Life. At one time, David also served as chairman of West Side Christian School, where Sandra coached girls volleyball.

It’s not clear exactly when trouble started brewing for the Duysts, but on Nov. 19, 1998, a severely wounded, bleeding Sandra crawled to a neighbor’s house for help, explaining that her horse Dexter had kicked her in the head while she was trying to feed him.

She would survive her injuries, but suffered from mood swings and depression afterward, according to people who knew her well.

Her personal physician, James Veldkamp, would later testify that she improved after he prescribed Paxil for her.

In 1999, she and one of her horses placed in the Top 5 at the All-American Quarter Horse Congress in Columbus, Ohio.

But on March 29, 2000, David Duyst called 911 and said his wife had committed suicide in her bedroom and was dead.

Improbable injuries. He told police that he had fallen asleep in the TV room and the sound of a gun woke him up. Sandra, 40, had shot herself with the couple’s Smith & Wesson 9-millimeter semiautomatic, he reported.

David, who admitted the couple had marital problems, told 911 that this was not Sandra’s first suicide attempt.

His story sounded credible until an autopsy showed Sandra suffered two bullet wounds. People don’t generally shoot themselves twice in the head.

Splatter revealed. David said the pistol must have double-fired, but testing of the gun disproved that theory. And two forensic medical doctors, Stephen Cohle and Vincent DiMaio, concluded that each one of her wounds was lethal enough to disable her immediately, which ruled out the possibility that she deliberately shot herself a second time.

She had no blood splatter on her arms or clothing.

Meanwhile, in another case of a murderer who didn’t watch Forensic Files often enough, David voluntarily handed over the clothes he wore on the night Sandra died.

They looked clean enough to the naked eye, but a lab found tiny drops of high-velocity impact mist blood on David’s shirt.

Financial woes. And more incriminating news: David was having an affair with his secretary, Linda Ryan, who for some reason wanted to have the jerk all to herself.

Ryan, who kept a collection of Beanie Babies on her desk at work, admitted that she and David planned to split with their spouses so they could be together. She divorced her husband and started checking out engagement rings online, but David dragged his feet, according to Beyond the Grave.

There’s more: David and Sandra were in debt, behind on tuition for their kids’ schools.

And to complete the Forensic Files homicidal-spouse package, David had recently taken out life insurance on Sandra that would pay out $579,000, even in the event of suicide.

Mary Ellen Spring, Sandra’s sister, chimed in with another revelation. Sandra had told her that if anything happened to her, she should look for a piece of paper hidden in a china cabinet.

Far-fetched explanation. The letter written by Sandra told a different story about how Sandra got those head injuries in 1998. The couple had been arguing in the barn about money, and David struck her on the head with an ax-hammer her while she was feeding Dexter.

The document was the kind of voice from the grave that makes a prosecutor’s day for a month.

David fought the accusations, playing an answering machine recording of Sandra saying that he had pushed her “beyond” and that their marriage was over and so was her life.

He claimed that she meant the second part literally. Defense lawyer David Dodge alleged that Sandra had shot herself twice in order to frame her husband as a murderer — an act of revenge for his infidelity.

David, 41, also contended that his wife had reason to be severely depressed at the time of her death, because he had just asked her for a divorce and told her that he “had an excellent chance of gaining custody of the children,” according to court papers.

Children faithful. His lawyer also said that the six-figure payday on Sandra’s life shouldn’t count against David: Insurance salespeople tend to take out large policies on their spouses to set a good example for their clients, Dodge contended.

The testimony of the couple’s children, who all reportedly believed in their father’s innocence, was a mixed bag that alternated between helping each side.

Erica Duyst, 13, testified that after Sandra recovered from the head injuries, she seemed depressed.

On the other hand, eldest child David Jr. and youngest Tim, 11, both said that on the day their mother died, her mood seemed fine. They also both testified that Sandra disliked guns.

But the boys also said that, after they awoke to the sound of gunshots on March 29, 2000, they heard their father’s footsteps coming from the TV room and moving to the bedroom — suggesting that Sandra was alone in the bedroom when the gun fired.

Forensic folks. Peter Duyst, the children’s grandfather, also supported David’s innocence. He had already suffered the death of his son Peter, a police officer who was electrocuted while trying to save a drowning man in 1994, according to the Grand Rapids Press.

Most of the testimony from forensic professionals helped the prosecution, however. Crime scene reconstruction expert Rod Englert said the death scene evidence was “consistent with someone firing the fatal shots while standing behind Sandra,” according to court papers.

Lovable guy? Sandra’s friend Cindy McCullough, who appeared on the episode, said that even after the horse stable incident, Sandra loved David and wanted to salvage the marriage.

As reporter Doug Guthrie wrote in the Grand Rapids Press, David Duyst did have some charm:

“Wearing a double-breasted blue blazer and looking every bit the insurance salesman he is, Duyst had jurors laughing and at ease almost immediately. Duyst exchanged smiles with his three children, who also appeared in the packed courtroom today. And he smiled as he told jurors that his eldest son — David Duyst Jr. — today is celebrating his 16th birthday. ‘He is getting his license today so watch out for the white Suburbans out there,’ Duyst said with a laugh, drawing smiles from jurors.”

But to others, his attitude didn’t sit right, especially when he unreluctantly badmouthed his late wife, alleging she had a negative attitude toward life.

Duplicate doubted. A jury found him guilty in March of 2001 and he received a sentence of life without parole plus two years for a felony firearms conviction.

In an interview with Wood TV8, juror Marie Hopkins commented that she felt David was cocky and overly relaxed on the witness stand. “No one could shoot themselves twice in the head,” she added.

The children the couple shared stayed with their maternal grandparents during the trial, but it’s not clear who took care of them long term.

Today, Tim Duyst appears to have a career in the military. Erica Duyst works in the health care industry. It’s not clear what David Duyst Jr.’s occupation is but, like the other two, he still lives in Michigan.

Their father’s obituary notes that both sons are married and that there are grandchildren in the family.

Finally, after researching Sandra Duyst’s life, I need to alter my theory that a typical case of low self-esteem made Sandra cling to the same man who struck her skull with a heavy implement.

The Grand Rapids Press reported that Ronald Baker, a pastor at the family’s church, said that “Sandra Duyst had been an assertive and confident woman before the incident, but became distant and timid after. He attributed her behavior to headaches she was suffering.”

It takes strength and initiative to exit a bad marriage, and the traumatic injuries Sandra suffered could have snuffed out her fortitude.

For all we know, Sandra at first covered up the ax attack because of embarrassment and then David Duyst begged her to forgive him — and put on a sweet, remorseful husband routine just long enough for him to figure out a way to finish the job.

Bids for freedom. He ended up serving his time at Saginaw Correctional Facility, which doesn’t sound like any country club prison. The facility is surrounded by a “buffer fence, double chain link fences, razor-ribbon wire, electronic detection systems, an armed patrol vehicle, and gun towers.”

But the convict never gave up hope. He busied himself with appeals, including the ever-popular ineffective counsel claim.

He had no luck with the legal maneuvering and died after a short illness at age 58 in 2018.

(Duyst was fortunate to pass away of natural causes — a Saginaw inmate was recently found dead of blunt force trauma in his cell after his roomie allegedly beat him with a Master Lock tied to an electrical cord.)

More family woe. Lawrence and Sarah Bos paid tribute to their murdered daughter via a $3,000 scholarship for physical education or recreational majors at Calvin College.

Even more tragedy was to strike Sandra’s parents, when yet another adult daughter, the aforementioned Mary Ellen Spring, died prematurely.

You can watch the Beyond the Grave episode about Sandra Duyst’s murder on Daily Motion. It’s more of a dramatization than a documentary, but it features commentary from some of the real-life professionals involved in the case.

That’s all for this post. Until next time, cheers. — RR
