12/21: This article has been updated with more details and the name and age of the victim.

There was a stabbing at the corner of 8th and Upshur Street (young man found in the yard on 8th Street next to the defunct Riyad market).

The Lieutenant on the scene wouldn't give me any information, but I spoke to several bystanders on the scene and got some background. Here's the most up-to-date publicly available info from MPD, sent by Commander Manlapaz:

At around 5:30 PM, MPD received a call for a person suffering from stab wounds in the 4100 block of 8th Street, NW. The victim was taken to a local hospital but succumbed to his injuries. His identity is being withheld until his next of kin has been notified.

Anyone with information regarding this offense is asked to contact the CIC at 202-727-9099 or text at 50411.
