Contact your local police to get the paper work, find out how to fill it out and how to serve and file the notice.

Have you called the police WHILE the incidents are happening?

My wife did that about a year ago, about 10 seconds before the police shined their flashlights into the house with Arlo.I would suggest Arlo indoor cameras.  

Since it wasn’t a signed contract between us, we have gone ahead to report to all the authorities, fortunately, our local police is very diligent in investigations and we’re cooperating with them to fish these criminals out, but it doesn’t end there for me!

I work as a police officer out of Louisville.

The police basically told her even if they commit a murder you have to give them 30 days. 

She needs to get with the police to resolve this on her end and get rid of him.

If there is a party and underage drinkers, the police will ask who owns the house and you will be held liable.

Luckily if they do, most courts will give you the unlawful detainer if you request it, and setup another date for a hearing about the monies owed.Unless a judge gives you "immediate possession", the tenants has 10 days to get out from the court date, if they are not gone on the 10th day, you then have to wait 72 hours before filing a Writ with the clerk, which tells the police departments to setup a time to come out and remove anyone from the property.Once you have your writ, you will get a call from the PD to schedule a time to perform the eviction.

I understand how regulations are enforced as opposed to assuming how the fair housing police operate.
