Police were searching for suspects late this afternoon in a shooting that wounded four people in northwest Washington.

Stuart Emerman, the assistant chief of the Washington Metropolitan Police Department, told reporters that there is no description of any suspect at this point, though he named Raymond Spencer, 23, as a person of interest. It was not known if Spencer is currently in the area.

Spencer is not a suspect, Emerman cautioned. But police are aware of a video uploaded to the internet message board 4chan that appears to show the shooter opening fire on Edmund Burke School, a college prep school in northwest Washington. The video was uploaded by an individual using the name Raymond Spencer, and police want to speak with him to determine whether he was involved in the shooting.

A man and a woman are in stable but critical condition, Emerman said, updating an earlier report from a police source who said two men had been shot. A girl is also being treated for a minor gunshot wound. All three are being treated at local hospitals.
