[UPDATE BELOW] Fliers are circulating at Zuccotti Park today with the photo of 18-year-old Aaron Schmidt, a freshman at the University of South Dakota who was reported missing by classmates on Wednesday. He has not made contact with his family or friends since Tuesday, and his phone is shut off, but his family traced his student credit card to Omaha, Nebraska—where he bought a one-way bus ticket to Manhattan. Now his father and uncle have flown here from Wisconsin to search for the 18-year-old Political Science major, whom they believe is occupying Zuccotti Park.

Schmidt's uncle, Al Boelter, told us, "He left and didn't tell anybody. He's 18 years old, it's his first year in college. He left with $40. He has no money. He came with the clothes on his back. We put $500 on his credit card so if he checks his credit card he's got cash."

And while the family says Schmidt is emotionally stable, they are worried about him being on his own in New York City. Boelter explains to us, "He's intellectually smart, however, he's not street smart. He doesn't have a clue, he doesn't know what he's in for. He's from the Midwest; he's from Wanake, Wisconsin. Aaron's a very independent kid and strong minded and I don't have a problem with him coming here, I'm just worried. I'm not here to try and pull him away. If this is his belief, I'm gonna let him keep his belief. If I see him I would just tell him, 'Aaron, you need to call home.' He's just a boy."

Schmidt is believed to be wearing the same red and black Columbia ski jacket as is depicted in the photo the family is circulating, and is said to have a small build. If you see him, his family asks that you contact them at (920) 250-0117 or Alex Borders with OWS Press and Legal at (646) 479-5215.

Update: Smith's uncle Al tells us, "He's in midtown. We're going to meet him now. He's broke and has nowhere to go, and he finally replied to a text message. He can stay here, we just need to know he's okay." His uncle told us Schmidt was at Occupy Wall Street, but did not yet know what he was doing in midtown. "He's lost," says Boelter. "He's up in midtown somewhere. He doesn't have a clue."
