Last week, a Kingsbridge Heights man went berserk, allegedly slashing his wife’s stomach, before going out on a fourth-floor windowsill, where he kept police at bay for 13 hours.

Police and paramedics were called to 2467 University Ave., at just after 1 a.m. on Thursday, Nov. 6, where they discovered Carmen Velez, 49, slashed across the abdomen. While they tended to her, her husband, Adolfo Jones, also 49, bolted from police to a back room and climbed out the window.

Several hundred people in and around Devoe Park watched as Jones, a New York City Traffic Enforcement Agent, dressed only in a pair of bloody boxer shorts, hung from the window frame. He often stretched his legs and kneeled for rest.

“They took someone out on a stretcher who was all bloody,” said one witness who watched the real-life crime drama unfold from her Kingsbridge apartment. The witness, who declined to give her name, recalled, “The guys on the corner (of East 189th Street) were yelling for him to jump.”

Police set up a giant airbag on a nearby roof, and a smaller airbag and net in the courtyard below.

Hundreds of people heading to work and school were inconvenienced as police choked off surrounding streets with giant, fortified police trucks, dispatched from all over the city. School buses were not allowed to pick up children and city buses were re-routed away from the area during the standoff.

“I don’t have cable and this is better than CSI,” one local resident confessed.

Just before 2 p.m., two Emergency Services Unit officers rappelled down the face of the building, grabbed Jones, and wrangled him inside the window. The crowds below applauded.

“It was very dramatic,” said Dalconeris Garcia, who lives across the street from the building where Jones lives. “You were doubting if he was really going to jump or not.”

  Jones was taken to a local hospital for psychological evaluation. Velez was reported to be in critical condition at St. Barnabas Hospital.
