Contrary to earlier reports, we now know that missing Brown University undergrad Sunil Tripathi is not a suspect in the Boston marathon bombing. Mike Mulugeta also is no longer being named as a suspect.

The confusion arose after those two were named as bombing suspects early this morning on Boston Police Department scanners.

Those scanner reports were disseminated far and wide on Twitter. The Anonymous tweet above, for example, has been retweeted more than 3,000 times.

Here’s a small sampling of people who tweeted the incorrect names (based on accurate transcription of the information conveyed to officers on the police scanner):

The surviving suspect has now been identified as Dzhokhar Tsarnaev, 19. He has not been captured. His brother, identified as 26-year-old Tamerlan Tsarnaev, is reportedly dead.

Update:

We have clarified this post to indicate that tweeters accurately reported what was said on the Boston P.D. scanner. It remains curious that Boston Police disseminated that specific information so widely to officers.
