Additional details have come out in the search for 22-year-old Evan Flanary, who was allegedly on his way to meet a contact from a social media app before he went missing nearly a week ago on June 19th. According to one commenter on SFAppeal who says she's Flanary's sister, Flanary was last seen on the 400 block of Harrison Street near Fremont Street in SoMa around 5:30 p.m. last Tuesday.

According to KTVU, who picked up the story over the weekend, Flanary has no history of any medical or psychological conditions and wasn't known to be on any medication at the time. He was last seen wearing blue jeans, a gray hooded sweatshirt, a "Cal" baseball cap and a backpack.

Police have yet to stay which social media app Flanary met his contact on, but social discovery apps have been gaining in popularity recently. Grindr, the location-based app for meeting gay men, is arguably the most popular locally and has its own straight counterpart. Meanwhile, San Francisco-based Skout — which billed itself as a location-based flirting app — was recently implicated when three separate teenagers reported they were sexually assaulted by people they met through the service. Likewise, social discovery apps like Highlight, Banjo and Sonar, which use Facebook information to find potential new friends nearby, were also all the rage at SXSW this year.

As the CEO of Common Sense Media, which aims to protect children and families online, told KTVU yesterday: "The mobile app space is like the wild, wild west right now. There are no rules, so in a world where there's no rules and no sheriff problems can happen and I think that's what we're starting to see." The bottom line, as we've always seen with online services: please be careful and aware when giving out your location or meeting strangers from the Internet.

Anyone who may have seen Flanary is encouraged to call SFPD's missing persons unit at (415) 558-5508.

UPDATE: He's just fine. He fell in love and his cell phone died. The end.
