Guglielmi said that police are working “round the clock” to find those responsible.

Johnson and three others were shot as they sat on the porch watching the game on the porch of the home in the 1700 block of Cliftview Ave. Shawnta Little said her son was shot twice in the head and once in the neck and leg. A bullet lodged in his spine. He died two days after the shooting. The three other teens were slightly injured.

Guglielmi said that “we have a direction that we’re going in, and that we’re looking at, I don’t want to say too much to compromise the case. We need some additional evidence to further our progress, additional witness testimony for corroboration.”

Police believe that the shooter — or shooters — live in Baltimore, perhaps even in the Lake Clifton neighborhood where the shooting occurred.

“As the police commissioner said, ‘The individuals did not come in from California, they did not drive down from New York to commit this murder’,” Guglielmi said . “These are individuals that are in that neighborhood. We know this. The community knows this, and we really need to do some justice for Sean here to find the individuals responsible for his death.”
