Tenant is in mental hosptial and threaten to kill me, any advice

[Kevin Huang]

Hello, I have a tenant who rents out a room in my house. He has been involuntarily admitted to a local mental hospital twice because he is a threat to others (5150) this week. He just got out 3 days ago from his first 5150. Last night, I went and checked upon him. He became very violent threatening to hit and kill me. He pulled out a gun (police later found out it was a fake) and pointed it at me while threatening to kill me and my family. I manage to deescalate the situation and called the cops. They booked him and took him to the hospital for another 5150. I have the whole thing recorded on my phone and sent everything to the police officer.

I have pressed the criminal threat against him. I am also looking to evict him from my house. I also heard it may be faster to get a restraining order and get an immediate move out order from the court.

Here are my questions

1. I have never filed a criminal charge against someone before. What happens after I press my charges?

2. I will be calling the courthouse first thing Monday to try and get an eviction/restraining order. But, I will like to get some more information before doing so. How long will it take to get this through the system, and which one would you guys suggest I choose?

I live in Southern California.

P.S.
He also owes me rent for the month of October if that helps at all.
