Soul Sucker

My name is Archibald Mayweather, I was 7 years old when I watched my mother suck the soul out of a gentlemen, whom she had bed thrice that month alone, for the first time. Leaving him an empty shell. He was found a day later crumpled and deformed, deposited by the river on a sandy bank. Though no one knows for sure, he was thought to have simply jumped off the bridge into the rushing white water. His body mangled by being crushed and sliced by sharp rocks down the river. Suicide ? Maybe. But I know that's not what happened, it's too much of a coincidence, with three other suicides shockingly so similar in the towns near to mine, it's reasonable cause for suspicion.
