Previous tenant violent - claims to have prop inside

[Kimberly Fisher]

We bought our 1st rental property in March, 2022. Our current tenant, was in place when we took possession. She pays on time, communicates with us and seems to be fine.
Apparently, a former tenant, from before we owned the property, was incarcerated and has since been released. She claims that she has property inside the unit and has been harassing the current tenant. According to our tenant, the other woman has come to the house repeatedly and has been harassing our tenant. Tonight the former tenant became very agitated and threw a brick through the front window. Unfortunately, there is no proof that it was the former tenant.
Our current tenant notified the police, we plan to get a copy of the police report and we will replace the window first thing tomorrow. I think we will install video security cameras asap as well.

Has anyone encountered anything like this? Anyone have further advice? Crazy stuff…. Thanks for your ideas and advice!
