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.
The unsubstantiated information (aka bystander rumor):
A young male was found unconscious in the fenced in area in front of 4100 8th Street shortly before 5:30pm. MPD was called and found the male stabbed and unresponsive. He was taken to the hospital but didn't survive (I saw the ambulance leave without its lights on and not at a rush, so make of that what you will).
Second Update for 12/21: From MPD: "The decedent has been identified as 17-year-old Jose Ochoa of Northwest, DC."
Update 12/21: I spoke to the person who found the victim and called 911. He said he saw the victim lying face-down on the on the sidewalk next to the Riyad. The victim appeared to be a late teen, early 20s Latino male. The witness saw no blood on the ground. Another couple arrived on the scene moments later, and reportedly said that the victim lived in the neighborhood. MPD showed up moments later, found no pulse on the victim and called EMS. The person who first found the body mentioned he saw no altercation or unusual activity.
I was told by a different bystander that someone saw three Latino males running down Upshur Street toward Georgia Avenue at 5:30pm. (The person told MPD this info.) The police were searching the ground in the immediate area with flashlights for evidence, and a number of detectives were on scene.
If you saw anything that night, please call MPD at 202-727-9099.
