"This is a heightened level of investigation, because a 12-year-old was shot," said Terry King, a homicide detective with the Camden County Prosecutor's Office before handing the fliers to residents.
Outside the apartment where the shooting occurred, pieces of duct tape remained on both sides of a window. Last week, a white sheet that read "RIP Tattoo Man" was draped across it. Neighbors said Moultrie worked out of his home as a tattoo artist.
Police created the sketch of the suspect based on eyewitness accounts. A motive remains unclear. Police said that they planned to interview the boy next week, and had not done so yet because he was in and out of consciousness from medications.
The block where he was shot was the scene of another homicide this year.
On Jan. 19, Confessor Santiago, 45, was beaten to death after a disagreement over money, police said. Rasheen Kelly, 32, of Camden, is charged with murder in the case.
Detectives say that case and the most recent shooting do not appear to be connected.
Police are offering $1,000 for a tip in the killing of Moultrie that leads to the arrest and conviction of the suspect, who they believe to be 5-foot-7 and 170 pounds.
