Ever walk into a rental and say to yourself, "This is where a murderhobo lives?" Total "basement in Silence of the Lambs" vibe.
The kitchen bathroom had a sewer grate of metal. That's probably where they buried the children's bodies. Or it might have been in the shared central heating cubby with all the dust and cobwebs and killer clowns.
Nice kitchen though! For a murderbasement. But the lack of a walk in cooler and meat hooks kinda makes it tough to use the kitchen for it's intended purpose.
