Hey Gramma
I am really feeling for you right now and how worried you must be for Steve. By all accounts he looks like a fun and happy guy with a lot of friends and loved ones that want him home. I hope this has a good outcome. We did recently have a girl that disappeared from her home in LA and was found alive 6 months later at a commune in northern california. Sometimes people really can just up and leave it all.
This site is mainly an anonymous place that brings together a wide variety of people (including professionals, retired professionals, those with special research or search skills/resources) to help "sleuth" out tips and support the families of those who have disappeared or fallen victim to a crime. Everyone has different reasons for doing it, but I feel comfortable speaking for most of us here when I say the main reason is because we have a deep appreciation for life and believe everyone deserves to be found, remembered and anyone that hurt them caught.What we are not interested in is divulging unrelated private details publicly (ie doxxing), compromising the investigation with anything we say publicly, or psychics.
With that said, I'd like to offer you the following if it is helpful for you or Steve's girlfriend on things you can do on your own:
1. Get in touch with the AWARE foundation on facebook who can help spread the word and offer other assistance such as how to start and maintain a facebook page for Steve
The AWARE Foundation, Inc.
2. Missing and Homeless can also help connect you with organisations in your area and where Steve went missing that specifically work with the homeless. This is important if there is any thought he may be on the streets for any reason
Missing & Homeless
I have a few questions for you if you don't mind:
1. Was he agitated at the time he was last seen/left home?
2. Do you know what he might have wanted to travel to Bakersfield for?
3. Has he ever expressed a desire to go off the grid
4. Any known enemies/gang affiliations? (you can just say yes or no)
5. Drugs? (I understand if you don't want to answer this but it does help us sleuth or search the right people/areas if this is a yes)
6. Do you have any reason to believe he may have harmed himself?
7. Are there any stories you'd like to tell us about Steve or his life to give us an idea of who he is or to help ease your thoughts?
If no one is divulging where the car was towed, my guess is LE has it and will be dodgy about it until it has been processed.
