Help my brother and sis in law find their son

“Our son, Gavin left his apartment (in Simpsonville) near Greenville S.C. sometime around midnight Thursday March 24th. We have not had any contact with him since. It is extremely out of character and he left with only the clothes on his back and his wallet. He may be on foot or on a green mountain bike, and could be in neighboring cities and states to Greenville, S. C. If you happen across this young man, please let us know and/or ask him to call his Mom! Thank you all so much. If you could please include him in your prayers that would also be very much appreciated!”

My brother and his wife are on their way to SC to find Gavin. I don’t want them to have to worry about their finances right now. They have enough to worry about. Please help them if you can! Thank you!
