Recently acquired a duplex with one existing (tenant 1) vacant and one empty space. Last week, i received a call from a new tenant (tenant 2) that moved into the empty space reporting of a shooting that occurred in the early morning. When i arrived at the duplex, there was several bullet holes on the door, window and siding of tenant 1. I was also informed by neighbor across the street that in December there was disturbance with tenant 1 where people showed up and street fight etc... Btw tenant 2 moved out because they felt unsafe and have a couple month old kid. Tenant 1 has also said they feel unsafe and want to move out but i don't think they are serious. Is tenant 1 responsible for the damage to property? This is probably not going to be the last time there will be such damage to the property. How to deal with this situation?
