My question involves criminal law for the state of: Washington State

I was assaulted in my home by my Mother's boyfriend. He elbowed me in the face leaving my right cheek swollen and bruised. A police report was filed and he went to jail for a few days. Shortly after my Mom evicted me from the residence and I was left to find a place to stay while attending school full time and holding no job. My truck which I was in the process of getting registered was parked outside my Mom's house and was stolen about two weeks after the assault took place. The truck has a key-less ignition that can only be used after a switch which is connected to the main power is switched on. The switch is hidden within the steering column and besides myself the man who assaulted me is the only one who knows how the truck is operated and where the switch was hidden. I have filed a police report and was wondering what I could do beyond that.
