A 24-year-old Bed-Stuy woman fell four floors from the roof of her apartment building down a 6-foot-wide air shaft last night, and survived. It is not immediately clear if she fell of her own accord, jumped, or was pushed.

According to neighbors, the woman, who's first name is Lydia, has been living on the fourth floor with her boyfriend for three years. A Pratt spokesperson identified her as a recent alumna of the art school.

FDNY and NYPD officers responded to 1041 Bedford Avenue at 10:30 p.m., and rescued the woman from the air shaft. She was taken to Kings County hospital with a broken hip, but in stable condition. According to an NYPD spokesman, the woman "possibly jumped," following a dispute with her boyfriend.

Amanda Gamsby and her boyfriend William Murray live on the fourth floor of neighboring 1043 Bedford, on the same floor as the victim and her boyfriend. Gamsby says she heard the couple arguing before the incident took place, but didn't take it seriously at first because she was used to hearing a lot of dramatic noise coming from neighboring apartments.

Gamsby's bedroom window faces the building's central airshaft. She and Murray were settling into bed around 10:30 when they heard footsteps on the roof. Suddenly, "We heard an unbelievable sound of smashing glass coming through the window. Enough to make me jump out of bed," she said. "After the initial smash of glass, we just kept hearing crunching glass and this woman just crying and wailing."

Gamsby and Murray went up to the roof and shined a flashlight down the airshaft. "There at the bottom of the airshaft, on the biggest pile of broken windows you've ever seen, is the neighbor girl wobbling around and wailing incoherently," said Gamsby. Murray added, "She was sitting up and moaning and obviously injured. I wasn't sure if she had a red shirt on, or whether that was blood."

According to Gamsby, the building's previous owners had stored a stack of about 25 windows on the roof of the building. But soon after the new management company took over the building last April, someone threw all 25 windows down the air shaft. "I was in my bedroom [at the time] and I heard all of those broken windows bouncing," she said.

Around 11:45 last night, after the victim had been taken to the hospital, Gamsby says she was inside Bedford Express Deli, next door to the apartment, when the victim's boyfriend "came running in, asking 'Where's Lydia?'" Gamsby said, "I told him what happened, and he crouched down and looked really alarmed, and bolted across the street."

According to neighbors, NYPD officers questioned the boyfriend late into the night. "We're really not sure if he was home when it happened," Gamsby said.
