Four men -- three generations of one family -- were killed and a woman was injured when gunfire erupted on the Upper West Side this afternoon.
The horrific scene unfolded in an apartment building at 492 Amsterdam Avenue off W. 83rd Street after a 911 call was received at about 1:45 p.m., authorities said.
Police found 52-year-old Carlos Rodriguez Sr. and his son, 24-year-old Carlos Rodriguez Jr., dead in a bedroom. Eighty-seven-year-old Fernando Gonzalez was found dead in a bathroom. Police say 49-year-old Giselle Rodriguez was hospitalized with a head wound.
The alleged shooter, 44-year-old Hector Quinones was found dead after falling from the fire escape of the third-floor apartment, police said.
The grandfather was found shot in a bathroom, the father and son in a bedroom, and the shooter was found dead in the courtyard of the building, law-enforcement sources told NBCNewYork.com.
Police said the shooter fell from a back window of the third-floor apartment, it appeared, while trying to escape after the woman walked in on him.
Officials said that a woman had called 911 earlier in the day to say she believed her father and brother were dead in the apartment.
Police say they don't have a motive for the shootings, but are looking into the possibility that drugs were involved. Sources say it's believed the gunman had served time in jail with one of the deceased.
