If I were in CO it would be a very different story as I understand they are much more tenant friendly.Contact your the city police and ask if there is a landlord training program.

Unless you’re one of the ones partying hard and running away from the hundreds of police officers, it’s just not that much fun to be in that atmosphere.

Yes you should be able to evict the tenant where incident occurred,, They are responsible for actions of guests.A Crime free / Drug Free addendum spells it out but I'm sure you have Cause.The police will probably issue you a notice saying they want the people in that apartment to be evicted.I've gone thru a murder in my complex guy shot for 400.00 dollars worth of pot his girlfriend was given choice to move in 5 days or we would file eviction she left.We gave her deposit back to her.

We moved them to a hotel for the week and had our team descend upon the apartment.

@Rachel Pivonka google his name, as well as call the police station what they can recommend. ...

When I reported it to the police they said it was a you say she say thing and had to take her to civil court.  

Do I have the right to contact the police to ask this tenant to leave or is my only way out of this an official eviction?  

I'm a police officer and resident in central NJ and wondering about loan rates for officers?

Great advice, you may also be overvaluing a police officer as a tenant. 

We can analyze people movement and report incidents like this in real time.4) Alert immediately if a police car shows up, hear police sirens in the property or hear gunshots.5) (Controversial but likely legal): Monitor how many unique people are entering/leaving each door daily (from cameras in parking lots or corridors) and log that information.
