True Crime with Kendall Rae
Journalist Writes Eerie Facebook Post Hours Before Death: Who Killed Sarah Greenhalgh?
01 May 2025
Who was Sarah Greenhalgh and what happened to her?
Thankfully, though, by this point, police sirens could be heard approaching their house. And of course, when John heard that, he decided to leave. But before he did, he slashed her tires and knifed the side of her car before quickly getting into his own car and speeding off. And Debbie did end up filing an emergency protective order right after this incident, but of course, that did not stop John.
Before their first court hearing, he called her to let her know that he had burned all of her stuff. And truly, he did. He burned everything down to her wedding dress. And maybe that wasn't a memory that she even wanted to keep, but still, it just shows you the lengths that this guy was willing to go.
So she knows that she needs to get as far away from John as possible, and thankfully her parents were able to get her out of the state just while the protective order was being finalized, which, by the way, of course made him even more angry. And it turns out two days after the order was served, he got into a road rage incident with a motorcyclist who cut him off.
Apparently, he got the motorcyclist to pull over and then he just started wailing on him, like beat the living shit out of him. And thankfully, he was arrested for assault. Now let's just stop for a second here and put ourselves in the shoes of the detectives on this case, okay?
They have a murdered woman who had some kind of relationship with this guy who has a detailed history of violence and at least one documented instance of arson. And then get this. So Debbie also told them that when she was married to John, he admitted to her that he had committed arson on buildings before and that he had tortured animals.
And so, of course, it makes sense why they thought of him as a person of interest. Now, I guess he was ordered to take anger management classes in October of 2011, so maybe you could say that he worked through those problems by July of 2012. Maybe. But in May of 2012, he stopped going to those classes.
And not only was he not going and therefore not getting any help or making any improvement with his anger issues, but he also lied to his probation officer about not going. So a week after Sarah was killed, he was actually arrested and put in jail for like two weeks before he posted bail. And that wasn't his first time in jail that year.
He had actually been sentenced to 90 days earlier that year in April for violating his protective order against Debbie and calling her 23 times in a row. Now, 86 of those days were suspended, so he was only locked up for four, but the dude was clearly on a downward spiral. And so with all of this considered, detectives felt, understandably, that it was plausible that he was somehow involved.
I mean, you're looking at a man who is clearly prone to violence against women, but also has had violent episodes against men as well. And his life was going less than great. He has a history of arson. I don't know if things are starting to add up here. And again, of course, I have to be really clear, I'm not saying that he did it.
