An NYPD auxiliary officer was shot and killed by police after authorities say he unleashed a violent rampage in a Manhattan apartment, leaving his sister-in-law dead and another man severely injured. 

The 44-year-old suspect has been identified as Ubaldo Gomez. 

Police say he worked as an NYPD auxiliary officer at the 44th Precinct. In a video, it shows a man being rushed into an awaiting ambulance at 1 Saint Nicholas Terrace near West 127th Street in Manhattan. 

Police believe Gomez, who was off duty, followed his estranged wife to a building. Authorities say he shot and stabbed his sister-in-law when she opened the apartment door. 

Police say he then began a violent struggle with a 39-year-old man, who neighbors identified as the building super and the owner of the apartment. 

 

Officers say when they got to the scene, Gomez was attempting to stab the 39-year-old superintendent and was shot by an NYPD sergeant after numerous commands to show officers his hands. 

He was pronounced dead at the scene, as well as his 45-year-old sister-in-law. 

The building super was taken to a local hospital. 

Stunned neighbors describe hearing loud screams and banging just before police arrived at the scene. 

Gomez's estranged wife, who was not injured during the deadly domestic dispute, is cooperating with authorities. 

The NYPD tells News 12 that Gomez had no prior criminal record.
