A teenager who was killed in a brazen rush-hour hail of bullets next to the Essex County Veterans Courthouse Wednesday night was in a car that had been linked to other shootings earlier in the day, law enforcement sources said yesterday. The Essex County Prosecutor's Office identified the dead youth as Shaquan Solomon, 17, of Newark and asked for help from anyone who might have seen the shooting take place at South Orange Avenue and Rider Court at about 6 p.m. Solomon was in a green sedan that was riddled with bullets from an apparent assault weapon fired from another vehicle as it traveled east on South Orange Avenue, authorities said. The stricken vehicle traveled about five blocks before turning left and coming to rest on Martin Luther King Boulevard between the Essex County Hall of Records and Essex County Historic Courthouse. Some of the bullets struck windows in the courthouse. The victim was found slumped over in the front seat of the car with four bullet wounds, authorities said. "We're hoping someone saw this incident," said Paul Loriquet, a spokesman for the prosecutor's office. "It was lousy weather, but we still think visibility was pretty good."
