The crooked cop accused of fatally shooting his girlfriend and wounding her friend with a bullet to the head had even bigger plans. After officers arrested Jerry Bowens last week, they discovered a hit list of names titled "Dead Pool"—an allusion to a similar list in Dirty Harry. Bowens, a former NYPD narcotics officer who resigned last year in the face of corruption charges, apparently had three other victims in his sights. Two more of his girlfriend's female friends made the list because Bowens suspected them of setting her up with other men. And police sources tell the Post that number five on the list was an Internal Affairs Bureau cop who exposed Bowens's corruption, which involved stealing drugs from suspects and giving them to his own informants, including one who says she had sex with him. The last name was Bowen himself. His plan, apparently, was to commit suicide by cop after killing the IAB officer. But it was not to be; he's currently being held on a suicide watch at Bellevue.
