Do I have the right to donate/throw out her stuff?

So I had this roommate living with me for about a year and a half. Unfortunately she passed away mid December last year.

She told me she didn’t have any family except for her son, but he doesn’t care for her much. Husband also passed away. I left her bedroom intact until just now. I’m going to need this room in a week, I have to get rid of her stuff quick. I don’t have any phone number for her son or friends. Nobody called me or looked for me regarding her stuff in months. I’m not getting rid of any pictures, I’m saving all of them in case her son ever wants them. But right now I’m confused I need this room. There wasn’t any wake or service or funeral, not that I knew of at least... What would you do?
