One man was killed and another was wounded when they shot at each other on a Brooklyn street early Saturday, officials said.  The gunfight erupted on Flatbush Ave. near Clarkson Ave. in Prospect Lefferts Gardens about 4:15 a.m., hitting 33-year-old Jeffrey Middleton in the head as he sat inside his late-model white Ford Fusion, police and witnesses said. Middleton was rushed to Kings County Hospital, but couldn't be saved.  A short time later a 26-year-old man walked into New York Methodist Hospital in Park Slope with a gunshot wound to the chin. He was hospitalized in stable condition, police said.  Police believe the two men shot each other and charges against the surviving man were pending.  Neighbors were rattled by the bloodshed.  "It was at least eight or ten shots — it was a lot,” said one neighbor, who identified himself as Alex.  “It sounded like it came from different guns.”  When Alex ran outside, paramedics were working on Middleton. Another man was wailing nearby.  "He was standing by the car and screaming like crazy,” Alex said.  “He was screaming hysterically. He was yelling, ‘Oh my god, they shot my friend!’ and 'Someone please call 911!'"  Middleton was parked outside a Flatbush Ave. juice bar when he was shot.  "There was a little blood coming down his face and they were doing CPR on him on the ground outside the car," Alex added.  His devastated friends said he was going to a late night Jerk Chicken restaurant to get a bite to eat after hanging out with his pals.  "This is surreal,” said friend Pierre Baker, 35. "It's hard to understand. People sometimes live a certain lifestyle and something like this is not that surprising — but that's not him.”  Cops found a gun in Middleton’s car, officials said.  The shooting was picked up by the NYPD's ShotSpotter system where high-tech sensors detect the sound of gunshots and alert cops, police sources said.
