Tenant in Jail: neighbors seeing tenant using drugs in garage

[Spencer Herrick]

I have a tenant that was in property when I aquired it. He has been nothing but a headache for my neighbors and the police, despite him always paying rent on time. At the moment, he is apparently in jail for theft in another county. My neighbors say he is an avid drug user. The neighbor of this property is very nice and has been keeping me posted on the activity there. She stated that he has been using drugs in the house and apparently, one of the neighbors saw him shooting up in his arm while the garage door was open. I need to go down to the property and go in as apparently he left some windows open that need closed. This is my first rodeo with this type of thing. I need to get him out of there. Do I have grounds to do so? I have several police reports also. I also don't know what I should do if I find drugs or drug paraphanalia while there. Call the police I would assume? Looking forward to ending this all and getting him out of there! Thanks in advance!
