I live very close to where this crime occurred. This poor woman.
This creep Pabon did it. He has scratches on his arms, neck, and hands and left work early the night she disappeared and called in sick the next day. Five police cruisers have been stationed outside his house in Staten Island and are following him everywhere, day and night. LE knows he did it; they're just playing their cards carefully and waiting for enough forensic evidence to come in to arrest him.
Pabon had been making unwanted advances toward her for awhile. He lured her to the 8th floor, raped her I imagine, and then to keep her quiet put her in the air conditioning duct - alive. She no doubt died a slow and painful death. Also, the air conditioning duct in which she was found is on the 12th floor of the building, and Pabon was the only one in the building at the time she disappeared with a key to that floor - apparently that floor was out of use and full of air conditioners.
This jerk needs to be locked up forever, no parole. And I hope he gets "Bubba" for a cellmate. I love that his girlfriend and sister are saying he wouldn't hurt a fly, he is a sweet man, and that the police are just 'harassing him.' Give me a break. He did it. He'lll be arrested any minute now.
