Sean A. Jennings wanted to get rid of his wife, but didn't want to go through all the hassles of divorce (plus that pesky alimony thing). So he devised a clever plan to kill her. Here's the bizarre story of the haunted house attempted murder:
On the 7th of October, 2007, Sean Jennings started building a haunted house in the garage for his two kids to enjoy on Halloween.
Sean told his wife, who uses a wheelchair on a regular basis, that he needed her to take a few steps up on a ladder and measure a rope he was planning to use to hang a plastic skeleton from a beam in the garage ceiling. Of course he couldn’t just let her walk into the garage, he needed her to go in blindfolded.
He said that it was going to be a surprise. [...]
She was a few steps up on the ladder, with the blindfold still on when Sean Jennings put handcuffs on her and slipped a noose around her neck.

He had a change of heart and she tried to forgive him, but after a few days, called the police to report the crime and the evidence was found soon after
