According to Washington, D.C. police, four people have died after a mass shooting in Southeast, Washington, D.C.

A total of 9 people were shot during a drive-by rampage, and six others remain hospitalized. Fire Department spokesman Pete Piringer told WJLA that all of the victims are in their 20s and 30s, except for one person who is a teenager. Police have not released the genders of the deceased.

According to WJLA.com, multiple shooters opened fire Tuesday evening in the 4000 block of South Capitol St. City Police Chief Cathy Lanier told the media that the shooting prompted a police chase that ended in Oxon Hill, Md. Three men were quickly arrested, but have not been declared suspects. In addition, four officers received treatment for minor injuries stemming from an accident that occurred during the chase on the 5600 block of Saint Barnabas Road.

Only miles away on Galveston Street, a 10th person was shot. However, officials do not know if that incident was related to the previous round of shootings.

At a press conference, Lanier said, “We’ve made a lot of progress to stop gang retaliation and violence, and in the end if this ends up being some kind of gang retaliation, then shame on all of us.”
