Steven may have called his phone, but someone else could have called it the next day. I have been in touch with a few friends of his. They did not see depression. I know that does not mean much.
When talking to Steven's parents last summer, and them telling me Steven moved to St. George, he was at that time looking for work, but was working. I took down their number. When you are single, you can move around like that, and look for opportunities.
As of him driving around, I have done that too. I would get in the car and crank the music up. Sometimes when I was bored-just for something to do. Now,being older when i am bored, I call people,get on the internet, or shop. we all have our things we like to do
Steven did not seem to have a lot of close friends, a lot of money, alot of responsibilities(meaning a wife, kids, girlfriends, etc) i think when he ventured out, sometimes there were opportunities to visit old friends. Don't we all do that?
