The man was hanging out with his girlfriend in his fifth-floor home on Ogden Ave., drinking and smoking the substance K4, when he jumped at about 3:25 a.m., sources said.  “He threw himself out the window,” his girlfriend told a neighbor.  The man was rushed to Lincoln Hospital in critical condition and died at 7:45 a.m., officials said.  K4 is four times more potent than conventional marijuana and can cause hallucinations.  Neighbors at the Highbridge apartment said the tenant repeatedly showed signs of erratic behavior.  "He was into drugs," said one neighbor, who didn't want to be identified. "He would do crazy stuff, like running up and down the stairs and going up and down the fire escape.”  Another neighbor had just gotten off his shift driving a livery cab when he pulled up and saw the naked man sprawled out on the sidewalk.  "I had just parked and when I came across the street and I saw him laying there on the sidewalk, completely naked," said Felix Rondon, 23. "I was like 'What the hell is going on?' I just kind of panicked and I ran over to him and I called the police.”  A few moments later, the man’s horrified girlfriend ran out of the building.  "She started crying right away, she went over and she was talking to the cops," Rondon said of the woman. "It's crazy, it was terrible to see something like that.”
