question about stolen property

i allready did drop her i tried having her removed from my house but police said it cant be done and i have to just deal with her since she is technically my roomate, but since i pay all the bills now i can have her evicted once the rent is due if she doesnt pay. I just want to not have to hide shit in my own house i feel sorry for the girl and if i file a report and it ends up being her that stole the shit she goes to jail (she is on an ACD) for 6 months more and as much as i want her out my life i dont wanna put anyone in jail i wouldnt wish that on anyone.
