The second husband of the five-times-married woman now accused of poisoning her latest spouse with insulin says he's 'very surprised' he made it out of their marriage alive.
Sarah Hartsfield has been indicted on first degree murder charges for allegedly killing her diabetic husband, Joseph, by giving him too much insulin.
It was her fifth marriage, and she is also being investigated in the death of her fourth husband's ex-wife, and a fire at his home.
In 2018, she shot her then-fiancé, David Bragg dead, claiming self-defense.
Sarah Hartsfield, 48, allegedly killed her diabetic fifth husband with insulin in January.

HUSBAND #5 - POISONED WITH INSULIN: Joseph Hartsfield was Sarah's fifth husband.
The two married in February 2022 - a year after her fourth divorce
Now, one of her ex-partners is speaking out to reveal his fears that she was going to kill him when they were together.
'I'm very surprised I got out of the marriage alive,' Titus Knoernschild told in an interview this week after her indictment on murder charges.
He was worried she would kill him for his $200,000 life insurance policy.
The pair were married between 1993 and 1996 after falling in love as high school sweethearts.
After their divorce, he said she would randomly pop up and even call his new wife.
'She was like a bad penny — every time you'd turn around, she'd be there.
'She doesn't do it to confront you.
She does it to remind you she's there.'

HUSBAND #1: Titus Knoernschild, Hartsfield's first husband, has since come forward in relief his ex-wife was behind bars and could no longer hurt anyone else.
The two were high school sweethearts and married straight after high school before divorcing two years later in January 1996
FIANCÉ SHOT DEAD: In 2018, Hartsfield fatally shot David Bragg, in 'self-defense'
Hartsfield married four more times after their 1996 divorce, and was also briefly engaged at one stage to Bragg.
Her other three husbands - Michael Traxler, Christopher Donohue and David George - are all still alive, but she was involved in domestic disputes during her marriages to all three.
In 2018, she fatally shot Bragg in their home. She claimed it was an act of self-defense and was never charged.
In light of her most recent husband's death, police are now reinvestigating that case.
A year after Bragg's death, JetBlack she was married to George.
A year earlier, his long-term partner Becky Kunze died mysteriously.
Months later, George's home burned.
Now, that fire and Kunze's death are also being re-examined.

'ABUSED SON': Sarah's son, Ryan Donohue from her third marriage with Christopher Donohue, has been vocal about his mother's arrest.

George has also claimed in an interview with Dateline that Hartsfield wanted him to kill the new wife of one of her previous husbands.
She denied the claim from jail.
None of the subsequent husbands have spoken yet publicly at length about their marriages to Sarah.
Sarah was arrested in February and is being held on a $5million bond. It is not her first time behind bars.
She was arrested on March 11, 1996, for assaulting her second husband, Michael Traxler, at their home located on Rio Bonito.
At the time, Hartsfield was going by a different last name.
She remained in jail for about a week until the charges were dropped for an undisclosed reason. Meanwhile, her then-husband was given a citation.
It appeared Hartsfield had only been with her second husband for only a few months before her arrest.
Prosecutors have described her relationships as being 'short-lived.'
