At least 2 people I went to college with have bios. One became documentary filmmaker. I thought she was pleasant enough as a dormmate, but I don't think the administration liked her much. She's a bit nutty, but seems to have found her niche. The other is missing and presumed dead. He had a claim to notability as an academic before disappearing. He's not someone who'd do well as a missing person. Wikipedia won't say it without a reliable source identifying the corpse, but he's dead and has been since the day wandered off.

I thought a third guy had a good chance at an article, but it's just a redirect to the rodent he named himself after.
