@Green-Edge0 You'll have to approach this with some awareness that a reimbursement request from a previously unreviewed listing will be treated very skeptically.
The most important evidence you'll need on your side is a police report. I don't know what went down that created so much bloodshed that several pieces of furniture had to be thrown away, but "brutalized human" seems like a far more pressing concern than "stained apartment." Whoever processes your claim might have some reasonable questions about how seriously you take the safety of future guests.
