His mother Cathy Wilson of Haworth, Oklahoma, and his two sisters have created the site findmattwilson.org to try and find information about where Wilson might be.
Police say Wilson withdrew $400 from an ATM about 3:30 p.m. the day he disappeared and withdrew another $100 just over an hour later. But officers don't believe he was forced to make the withdrawals because he returned to his apartment later.
Wilson's roommate says he heard Wilson come in about 11 that night with what sounded like plastic grocery bags.
He was last seen just before midnight putting gas in his car.
