"Oh my god, I made a terrible mistake! I HAD BURIED THE MALICIOUS MONSTORIOUS DEMON ALIVE IN THE MALLABLE WALL WITH MY DEAD WIFE!"
The man accidently buried the cat alive with his dead wife in the wall, which revealed his previous crimes to the police. The police arrested him at the speed of light.
"You are under arrest for murder!!"
The man was arrested and taken to jail. He was furious with the cat because it exposed his crimes. He began writing his life story describing events that happened in his life, including why he ended up in jail.
If it wasn't for that annoying cat that got me caught, then I would have been the happiest person to step foot on earth.
"This is your punishment for murdering that lovely brown haired women."
