At approximately 2:20 p.m., the EMS lieutenant was on duty in the vicinity of 20th Avenue and Steinway Street in Astoria near her station’s quarters when she was stabbed approximately 19 times. 

She was transported in critical condition to Mt. Sinai Queens Hospital, where she succumbed to her injuries. She was reportedly six months from retirement. 

The suspect Peter Zisopoulos, 34, has been charged with murder and criminal possession of a weapon. 

FDNY Acting Commissioner Laura Kavanagh called the attack "barbaric and completely unprovoked."

NYPD Commissioner Keechant Sewell tweeted on Thursday, "The deadly, senseless attack on an on-duty EMT is a direct assault on our society."

Russo-Elling is the 1,158th member of the FDNY to die in the line of duty. 

She is the second EMS to be murdered on the streets of New York City in the past five years, Chief of EMS Lillian Bonsignore said in a statement, adding: "We need this city to stand up for Alison Russo; we need this city to stand up for EMS. We need this city to stand up for all of our first responders who serve you and your families so selflessly, unselfishly and so giving."

"It is a tremendous loss that we will feel for a very long time to come. It is very sad that the department has to go through this over again. There are no words that can express the pain that we are all feeling. My heart goes out to her family and her parents, and everyone in the station that is feeling this horrendous loss. She was always looking out for everyone, always someone you could talk to," FDNY Lieutenant Nancy Leger said in a statement shared on the FDNY’s Instagram on Sunday.

"Lieutenant Russo had a heart of gold; she was here for the whole station, she made sure that we were all ok. We are a close-knit station. She made sure everyone went home safe. I have known her for over 13 years, she was the mother of the station. She was full of life; she was such a great person. It is a tragedy that we have to go through this again," FDNY Paramedic Madelyn Higueros said.
