You have to be stupid to hire a killer these days. Most of the adds online are fakes set up by the police and you can't even be sure if the guy won't scam you.
It's really funny why there are people who think that hiring killers online is legit, though I'm not really sure but logically how are these people gets the job done especially when you're from the other side of the globe. And yes, if there is going to be a killer for hire online that could be just an entrapment operation for the authorities trying to capture some criminals online.
What would she say? I hired a killer and he didn't do his job?

The story is really shady, I don't get to see the source, could have been a made up story. I'll buy into this story once a credible source shows up.
She couldn't find a better way, hiring someone who she personally met is more stupid.
If I have to put my self in her shoe, I couldnt find a better way than seeking an online hitman, most likely on the deepweb so it can't blackmail me to ask for more than $5k. If she just desperately wanna kill the husband, she should just be the one to do it. Its however going to take a pro of the pro to get away wit hthe forensic investigations.
