Three people, including two juveniles, were shot and wounded in a Northeast D.C. park Wednesday morning, police say.

Police received a call shortly after 9 a.m. for a shooting at Marvin Gaye Park in the 5300 block of Dix Street NE. Officers found two juveniles — ages 13 and 16 — and an adult who had been shot, police said. The victims were conscious and breathing, and their injuries are not believed to be life-threatening.

"Whenever we have young people that are shot in the city, it's a very, very serious concern to all of us," D.C. Police Chief Pete Newsham said Wednesday morning. "And the fact that these are school-aged children, we'll have to look into why they weren't in school when school started."

The reported shooting is blocks from H.D. Woodson High School. The school was placed on lockdown, according to D.C. Public Schools.

“This is less than a block away from where Makiyah Wilson was killed,” Ward 7 community activist Jay Brown said, referring to the 10-year-old girl shot as gang members fired at rivals in July 2018. “This community has not healed, and the resources needed to heal are not there right now, and I'm concerned about the kids that witnessed the incident, the kids that did not go to school after the incident.”

Many students cut through the park on their way to Woodson of Kelly Miller Middle School.

“My daughter goes to school that way, and if it would have been her walking out here, that could have been her,” said Lisa Evans, mother of a Woodson student. “It's really ridiculous. That time of the morning. Who does that?”

Two K-9 units were called in to help search the park for the gun.

The teenage victims are students at schools in D.C. but not in the area of the shooting, Newsham said.

“These were school-aged children who should have been in school, so we are trying to figure out what exactly happened,” Mayor Muriel Bowser said.

There is no motive known at this point, Newsham said

The police chief said there is a lookout for one person, a male who appeared to be in his teens and was wearing tan pants and a black shirt. Earlier police had tweeted there was a lookout for two juveniles wearing white polo shirts and tan pants.

There didn't appear to be any connection to a double shooting in D.C. overnight, Newsham said.

A community group told News4 it wants to start a safe passage program to protect students and senior citizens in large parts of Ward 7.
