Police are searching for two teens — one charged with murder, another with robbery — in connection with the death of a Rockville teen.

John Delonte Black Jr., 18, of Burtonsville, and Annbel Sierra Massilon, 18, of Silver Spring, are wanted in connection with the shooting death of 18-year-old Kennedy Merritt-Millet, Montgomery County police told reporters on Friday.

Black is charged with first-degree murder and Massilon is charged with robbery, police spokeswoman Shiera Goff wrote in an email to Bethesda Beat on Friday.

Police were called to the intersection of Greencastle Road and Turbridge Drive in the Fairland section of Silver Spring around 11:16 p.m. on Tuesday for the report of a shooting, police said. Officers found Merritt-Millet lying there with injuries that they think were from gunshots.

Capt. Ruben Rosario, the director of the department’s Major Crimes Division, told reporters Friday morning that police think Merritt-Millet was shot after an altercation involving Black, Massilon and others.

Rosario said detectives don’t think the suspects knew Merritt-Millet, but that Black and Massilon knew each other.

Asked how many people were involved in the altercation, Rosario said he thinks there were at least two people on each side of a dispute. Police don’t think it was gang-related.


Police are distributing fliers with Black’s and Massilon’s names, addresses and photos. They are asking anyone with information to call the Major Crimes Division at 240-773-5070.

Rosario said on Friday that both suspects should be considered armed and dangerous.

“We’re not asking for them to be confronted. What we’re asking for, is if you see them anywhere in the public or the community, to please dial 911,” he said.


As of Monday morning, neither Black nor Massilon had been arrested and police did not have additional information.
