Just a room with blood splattered everywhere.

This is my first relevant post to Reddit, but I beleieve it to be legitimately WTF worthy.

So I was working in Fitchburg, WI the other day installing some washers for my job. There was a leak and I needed to get a mop so I started looking around the basement for one. I went down to the storage area which was completely dark. I could just make out the mess on the wall when I found the light switch. after looking around for a corpse, which I did not find, I took some pictures and filmed this for my boss who later called the police, I don't know what happened with it yet. If it is legit blood, I'm guessing that person is pretty dead right now. Not just slightly.

Sorry for the long delay. I never did hear back from the police, but what my co-worker said (he's a tech for the company and frequents the property) was he talked to the building manager and they said some tenant had cut off a couple fingers with a circular saw while working on a project down…
