..4-year-old killed in Camden crossfire by Carly Rothman/The Star-Ledger Monday August 04, 2008, 11:23 PM A 4-year-old boy died tonight after being shot in the head while playing on a Camden sidewalk, authorities said.The child, accompanied by his mother, was playing in the 1600 block of Norris Street near his home when the first shots were fired around 5:20 p.m., said Jason Laughlin, a spokesman for the Camden County Prosecutor's Office."There was a crossfire, and he was caught in the middle of it," Laughlin said.Dozens of rounds were fired, but the child was the only one hit, Laughlin said.The initial shooter was apparently gunning for a specific target, according to Laughlin, but he declined to say how many shooters were involved or describe the cause of the conflict."A lot of what happens in Camden is drug-related, the drug trade has some part in it one way or another, but I can't say specifically in this incident," Laughlin said.The boy's mother was not one of the shooters and was not hurt, he said.The child was taken to an area hospital where he was pronounced dead, Laughlin said.Authorities late Monday issued a murder warrant for 20-year-old Donald Lindsey and said they are searching for the Camden resident.
