S is a freshman living on campus. We are 200 miles away.
His roommate, a sophomore, is off. He literally hid under a blanket during move in so as not to have to speak to us. He cries to himself in the room. He tends to stay out all night every night.
Roomie's mom has texted S that she is worried about her son and asking S if he is okay, if he going to class. She showed up one day, from 3 hours away, because he wasn't responding and they were so worried. He told S that he "almost didn't make it last semester."
He has been missing since Wednesday. His wallet, laptop and backpack are in their room. No one has seen him. He hasn't been to class. He isn't answering his texts or calls from S.
Yes, S has alerted he RA. S is also spending the weekend at his gf's room because he says he is certain the roommate either has or plans suicide given his general demeanor and the way he talks. And S doesn't feel safe in their room.
