A 26-year-old New York City woman has been charged with manslaughter and second degree assault for the death of an 87-year-old Broadway vocal coach. 
Events coordinator Lauren Pazienza, 26, was arraigned in Manhattan criminal court on Tuesday, and is facing 25 years in prison for the death of Barbara Gustern, a beloved Broadway vocal coach who died on March 15. 
Pazienza’s bail has been set at $500,000 cash or $1 million surety, according to the Manhattan District Attorney’s Office, which had sought to have her remanded to Rikers Island pending trial. 
The victim was walking towards a cab outside her Chelsea apartment building when she was pushed from behind on March 10. She was helped back to her feet by a cyclist and was taken to the hospital ‘covered in blood’ after hitting her head on the concrete pavement.
Gustern died from her injuries four days later.   

Before she lost consciousness, Gustern allegedly told police and a friend that a woman she didn’t know crossed the street, approached her directly, called her a ‘b***h’ and shoved her ‘as hard as she had ever been hit in her life.’ 
Charging documents allege that the assailant, later identified as Lauren Pazienza, hung around the area for another 20 minutes after the attack. She allegedly stood on 29th Street and watched an ambulance as it arrived at the scene.
The attack and her subsequent actions were caught by to surveillance videos reviewed by police. 

Soon after the attack, she went back home to Astoria, Queens, quit her job at a store in Chelsea, deleted all social media and took down a website advertising her wedding this June, prosecutors say.
The day after Gustern died, she allegedly fled for her parents’ home on Long Island and later stashed her phone at her aunt’s house so police wouldn’t find it. Pazienza’s attorney maintains that there is no proof that she pushed Gustern. 
‘What they have is a photo of someone who looks like my client getting on the subway. This attack did not happen on the subway,’ attorney Arthur Aidala said.

Among those in attendance at her arraignment on Tuesday were Lauren Pazienza’s Parents.
The couple were seen leaving Manhattan criminal court, New York, trailed by members of the media after their daughter’s court appearance.

At Tuesday’s arraignment, assistant district attorney Justin McNabney revealed new details of the case, including how an intensive NYPD canvass for surveillance footage led to the identification of Pazienza as a suspect.
Pazienza’s next court hearing has been set for Friday. 
Leading to her arrest, on Saturday investigators received got an anonymous tip that Pazienza committed the crime. The tipster also revealed that the suspect was hiding out at her parents’ house on Long Island. 
That same day, the NYPD released photos of a flame-haired young woman who they said was responsible for the attack. She appeared to be getting on the subway. 

The female suspect has now been identified as Pazienza, who lives in Astoria, Queens, with her fiancé. 
Pazienza worked as an events coordinator for the furniture brand Roche Bobois, but quit her role in December. It’s unclear what motivated her to assault the elderly victim.
It remains unclear if there is any connection between the pair or if it was a random attack.
