On Monday afternoon, this video was posted to a thread on /b/—the unruly, lawless “Random” board on the popular imageboard site 4chan—along with a characteristically sweet message: “Find this dumb little bitch and throw her into a river.”

The LiveLeak video page to which the /b/ thread linked listed what little information the video’s poster could glean from the short clip:

We can determine from the picture so few things.

One, based on assumption, she probably has a facebook account, no matter what country they’re in.

Two, she is 5ft 6in-5ft 8in, blond, eye color unknown, Caucasian

She has something written upside-down on her red sweater, barely legible, might be of assistance if it’s the product of a local store.

Let’s work together on exposing this sicko! Use the comments.

4channers quickly got to work. If there’s one thing /b/ is really good at (besides calling each other “fags”), it’s finding people—something we all learned the other week, when the board rapidly found a woman who dumped a cat in a garbage bin, and harassed her into confessing and apologizing.

They didn’t disappoint: The 4chan miscreants quickly identified the owner of the YouTube account that had uploaded the video, his hometown, and, possibly, his Facebook account. And not just that: /b/tards picked out two Facebook profiles they thought were most likely the girl in the video, as well as profiles of friends and the camera man.
