“The suspect who we believe is responsible is now deceased,” said Contee, who declined to provide the suspect’s name until the next of kin have been notified. “We believe the suspect took his own life when MPD members entered or broke through the apartment where the suspect was located.”
Police are not looking for another suspect, Contee said.
Officers recovered six firearms from the home where they found the suspect, Contee said, including “several long guns, multiple, multiple rounds of ammunition and also handguns.” The investigation is ongoing, he said, adding that police currently have no motive for the shooting.
He said they didn’t believe there were any other shooters besides the dead suspect and weren’t sure of any connection between the suspect and the nearby Edmund Burke School, a college preparatory school in northwest Washington.
“This was very similar to a sniper with a tripod, and this person obviously had intent to kill and injure members of our community,” Contee said, adding the suspect fired from north to south.
Contee said it appeared the suspect fired at people indiscriminately and not in any pattern.
When asked if the suspect was previously known to law enforcement, the chief said the preliminary information he received indicated no prior contact.
Earlier, Stuart Emerman, the deputy chief of the Washington Metropolitan Police Department, 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 warned. Contee declined to say if Spencer was the suspect who is dead, but said, “We are no longer looking for this person of interest.”
Police are aware of a video uploaded to internet message board 4chan that appears to show the gunman opening fire on the Edmund Burke School. The video was uploaded by a person by the name of Raymond Spencer and police wanted to speak to him to determine if he was involved in the shooting.
“At this point, based on what we’ve seen on social media, based on the information we’re investigating, we’re looking for a person of interest to speak to. This person’s name has come to light as Raymond Spencer. He’s a 23-year-old man,” Emerman said at a news conference on Friday.
A man and a woman are in stable but critical condition, Emerman said, updating a previous report from a police source that 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.
At a later media briefing, Emerman said a fourth victim, whom he described as a woman in her 60s, was hit by a bullet but did not require hospitalization.
One of the four people shot is a retired member of the DC Metropolitan Police Department, Contee said.
The shooting took place at the 2900 block of Van Ness Street Northwest, MPD said.
Washington Mayor Muriel Bowser said authorities would begin to lift a lockdown in Edmund Burke and students would be reunited with their families.
Samuel Nicolido, a college student who lives near where the shooting took place, told CNN he heard about 20 gunshots.
“It was like five shots and then stopped for like a minute and then four more, five more and then one more,” said Nicolido. “I saw cops everywhere with shields and then they said – they told us to stay home. Do not go. So yes, it was scary.”
Police are also investigating whether shots were fired at a deli about half a mile down the road from the original shooting location. CNN spoke to the deli’s owner, who said his window was hit by a bullet at 3:24 p.m. ET. A car parked across from the deli was also hit by a bullet, according to the car’s owner, who spoke to CNN.
There was also a bullet hole in the window of an optometrist a few doors down from the deli.
The video shows the shooter opening fire
The video uploaded to 4chan is incredibly shaky and has a red crosshair in the middle. It appears to have been captured by a bodycam worn by the shooter: it is time-stamped, 3:17 p.m., and the metadata shows that a video encoder was used, creating the video file from a bodycam and dashcam manufacturer.
CNN geolocated the video, which shows it was taken from an apartment building right next to the Edmund Burke School.
In the video, a closed bridge between two school buildings can be seen – a person with a backpack appears in one frame – before several gunshots are heard. The shooter appears to reload the gun once in the video.
CNN spoke to an eyewitness who confirmed that a closed bridge at the school, connecting two buildings, was blown up.
People in the closed bridge can be seen running. A man on the ground wearing a safety vest runs for cover between parked cars.
4chan did not immediately respond to a CNN request for comment.
The person who posted the video on 4chan appeared to mock the police who were looking for her in additional posts on the site.
