A Texas woman was convicted this week of killing her diabetic husband in 2023 through neglect as he suffered from an insulin overdose.

A jury found Sarah Jean Hartsfield, 50, was found guilty of murder on Wednesday, KFDM reported.

Hartsfield was arrested after staff at Houston Methodist Hospital noted suspicious circumstances surrounding Joseph Hartsfield’s death in January 2023, as CrimeOnline reported.

According to Law&Crime, prosecutors presented evidence showing that Joseph Hartsfield’s blood sugar dropped to dangerously low levels over several hours on January 7, 2023. Sarah Jean Hartsfield claimed she was sleeping while this happened, but her cell phone activity showed her on several apps during that time — and step tracking software showed her up and moving around.

Additionally, the husband’s glucose monitor went off more than 100 times times, each time alerting the wife’s cell phone.

Prosecutors acknowledged that they could not prove Sarah Jean Hartsfield had given her husband an overdose of insulin herself, but witnesses testified they believed that was what happened.

The jury took less than an hour to convict. She faces life in prison when she is sentenced.

Joseph Hartsfield was Sarah Jean Hartsfield’s fifth husband. She had previously shot a fiance to death in Minnesota. She claimed self-defense and was never charged in that incident.
