Important to focus on this: where did Graham and Matthew go after they left Tempo?
Graham and Matthew were last seen walking away from Temp restaurant at 1:45am on Saturday, September 13 toward the Downtown Mall. Did they turn left, in which case others might have seen them walking along the Mall, or did they turn right toward the Pavilion? Or did they continue straight up 5th Street? Also, might anyone have seen them at Lucky 7 on Market, the only place around the Mall open after 2am? I find it hard to believe that they left Tempo and walked toward the Mall and that no one else saw them after that. Spread the word! Did anyone see them after that? Speak up!
