Maybe they do it differently in Virginia, but where I live, most people get discharged from the hospital after a day or two. Only the really emotionally disturbed or crazy people are held for a month. As soon as they determine there is no liability by letting the person out, they are out the door. Why? Because it costs a lot to keep someone in the hospital!
I'm not a psychiatrist, but I'm both hospital security and an on call sheriffs deputy, so I meet these people and often know the outcome.
You guys are right, this doesn't seem to pass the smell test, but then again, only the doctor would know what's really up.
