The police won't be able to help you unless you have evidence of who it is, and if you can get a license plate number then you can back track the issue.

Then, regardless of what happens with the police, I will start the eviction process.I don't really care about marijuana.

I would police the new PM to avoid this problem in the future.

Make it clear that an employee has already admitted to the theft of your property and you'd like to resolve this without having to file a police report. 

Call the police and report it.

Did you file a police report at the time you discovered the furniture missing?

Now in my neighborhood, if a child at the bus stop had a gun, and an adult knew about it, the adult would call 911 and report it, and let the Patrol Officers end the situation for the safety of others, vs breaking the lease and moving away.The Police will end it, and when it's done they will be holding that gun--as evidence.Does she have no Cellular Phone--to let the fingers do the walking--911(???)

But her sisters mom has history of not paying rent and making police kick them out which seems to be a long process.

We saw on our video camera a police officer knocking on our MTR's door when no one was home.

Obviously, if the noise is excessive, they should call the police to document a complaint.
