The death of a famed New York City vocal coach who fell and hit her head after she was pushed during an unprovoked attack has been ruled a homicide as the manhunt for the suspect continues, police said Monday.

Barbara Gustern died Tuesday, days after a woman approached her from behind and pushed her just before 8:30 p.m. on March 10, the New York Police Department (NYPD) said. Police said Monday they were now treating her death as a homicide.

NYPD is seeking to question this woman in connection with the unprovoked attack on an 87-year-old woman in Manhattan on March 10, 2022

Gustern, 87, was in the area of West 28th Street and Eighth Avenue, less than a block from her Manhattan home.

The push caused her to fall and hit her head and left her with critical injuries, police said. Gustern was rushed to an area hospital, but ultimately could not be saved. 

NYPD Chief of Detectives James Essig called the assault "an unprovoked, senseless attack" and a "disgusting and disgraceful offense."

"That’s horrific. An 87-year-old woman, just walking down the street, knocked to the ground," Essig said at a press conference last week.

Gustern was a longtime singing coach who worked with Broadway casts and music stars including "Blondie" vocalist Debbie Harry, according to the New York Times.
