A Texas woman will likely be spending significant time behind bars for killing her fifth husband with a surfeit of insulin.

On Wednesday, Sarah Jean Hartsfield, 50, was convicted by a jury of her peers in Chambers County on one count of murder for the January 2023 death of her husband, Joseph Hartsfield, 46.

Various aspects of the defendant’s past proved to be both a sideshow and used in the case against her by the time all was said and done.

“You can just look at her overall history and you can tell that there’s a very evil side to her,” Chambers County Sheriff Brian Hawthorne told an assemblage of reporters outside of the county courthouse as the murder trial began in Anahuac — a small town located along a bay off the Gulf Coast and part of the broader Houston metro area.

The Chambers County Sheriff’s Office was called to a hospital in Baytown after Joseph Hartsfield, a resident of nearby Beach City, died — with the illness reported as suspicious, Law&Crime previously reported.

The sheriff’s office said there were inconsistencies discovered during the investigation that “made the illness appear more suspicious in nature” and ultimately led investigators to believe the death was the result of “foul play,” Waco-based CBS and Telemundo affiliate KWTX reported at the time of Sarah Hartsfield’s arrest in February 2023.

Among the pieces of the evidentiary puzzle provided to the jury was a bevy of allegations not directly related to her husband’s death — including her military training and never-pursued allegations that she was responsible for the arson of her grandmother’s home, according to a courtroom report by Houston-based NBC affiliate KPRC.

Prosecutors also had the defendant’s own children testify against her — a tactic that particularly stuck in the craw of Sarah Hartsfield’s defense attorney Case Darwin, KPRC reported.

In May 2018, the defendant shot and killed her then-fiance David Bragg in self-defense, Law&Crime previously reported.

Notably, however, Sarah Hartsfield was never charged in any of the preceding events singled out by the prosecution.

“She’s not on trial for being a bad person,” Darwin told the jury. “That doesn’t make you a murderer.”

During the trial, prosecutors suggested Joseph Hartsfield died as the combined result of his wife’s intentional neglect of his uncontrolled type 1 diabetes — and likely the intentional injection of insulin.

On the morning of Jan. 7, 2023, the husband’s blood sugar was dropping to dangerously low levels for several hours. While the wife claimed she was asleep at this time, prosecutors showed several pieces of data from her cellphone — activity on multiple kinds of apps and step-tracking software — which showed she was actually awake, active, and had waited quite a while before calling 911.

Over the course of that morning, the victim’s glucose monitor went off over 100 times — and the defendant received alerts on her phone.

Sarah Hartsfield, for her part, was on prescription narcotics on the day in question to recover from a recent surgery; prosecutors, however, juxtaposed her drugged state with the proven ability of the defendant to repeatedly use her phone, use Facebook, and even record her husband as he slowly faded out of existence before her eyes.

By the time medical personnel arrived, Joseph Hartsfield was in the throes of an insulin overdose.

While prosecutors acknowledged it was all but impossible to know whether the defendant herself had administered the fatal amount of insulin, the state aimed to leave jurors with the impression — and witnesses testified they believed — that she had done exactly that.

“The defendant made sure he got enough insulin so he couldn’t recover,” a prosecutor argued, according to a courtroom report by Houston-based Fox affiliate KRIV.

One of the deceased man’s friends, Ivan Boots, testified the defendant expressed concerns people would be able to determine the level of insulin in Joseph Hartsfield’s body. The same friend testified the victim often had high sugar — expressing surprise he would be hospitalized with low blood sugar levels, KRIV reported.

As the eight-day trial drew to a close, Darwin argued the state had failed to connect his client to her husband’s death, relying instead on “a story, a narrative,” about her character with a “kitchen sink” strategy. Admittedly, the defense attorney said, Sarah Hartsfield might have failed to render aid but said she had “no duty to act.” And, in a sharp break, insisted: “Joseph administered that insulin to himself” and that there was “absolutely no proof that Sarah administered insulin.”

As for the large amount of insulin likely responsible for the man’s death, the defendant had, in fact, offered several pens to law enforcement who arrived at the home in the initial stages of the investigation. But those pens were not collected into evidence.

“One hundred percent an error,” former Chambers County lieutenant Robert Hemmenway testified during trial.

The state acknowledged some of those deficiencies during its own closing argument — while stressing the weight of the evidence suggested Sarah Hartsfield intentionally killed Joseph Hartsfield.

“You get the picture,” a prosecutor summed up.

In the end, after an hour of deliberations, the jury did.

The sentencing phase of the case began more or less immediately after the defendant was convicted. She faces life in prison.
