We just received the following alert from a reader. Very tragic:

Suicide in Union Square, jumped off building, blocks closed off, assorted people freaking out...super fucked. My guy was walking down to that area and saw some block(s) around O'Farrell and Powell closed off and cops everywhere. Ambulance folk huddled around what is presumably a body. And (shudder) at least one person sobbing into a cell phone saying (correctly) that it's the most horrible thing she's ever seen.

The only thing we can confirm is that there was a suicide at the H&M building this afternoon. More info as it comes in.

Alas.

Update after the jump.
