Amy Cooper, the white woman who called the police on a Black bird-watcher in Central Park, made a second, previously unreported call to 911 in which she falsely claimed that the man tried to assault her, a prosecutor said on Wednesday.
“The defendant twice reported that an African-American man was putting her in danger, first by stating that he was threatening her and her dog, then making a second call indicating that he tried to assault her in the Ramble area of the park,” Joan Illuzzi, a senior prosecutor, said.
The second call was disclosed as Ms. Cooper appeared remotely in Manhattan Criminal Court to answer a misdemeanor charge of filing a false police report, which carries a maximum sentence of a year in jail.
Ms. Cooper had been charged in July, and no additional charges were announced on Wednesday. Ms. Illuzzi said the Manhattan district attorney’s office was negotiating a possible plea deal with Ms. Cooper that would allow her to avoid jail.
The hearing was the latest development in the Memorial Day weekend encounter that resonated across the country and reignited discussions about the potential danger of false accusations made to the police about Black people.
Ms. Cooper was filmed calling 911 from an isolated area of Central Park after a Black man asked her to leash her dog, as the rules required. During the first call, she said multiple times that an “African-American man” was threatening her, emphasizing his race to the operator as she raised her voice frantically.
Video of the encounter, shot by the man, Christian Cooper, on his phone, has been viewed nearly 45 million times. Its timing, one day before protests erupted nationwide over the police killing of George Floyd in Minneapolis, only deepened its role in sparking outrage over what many viewed as an example of everyday racism. (Ms. Cooper is not related to Mr. Cooper.)
But prosecutors said Ms. Cooper made a later call to 911, which was not shown in the video. In that call, Ms. Cooper told the dispatcher that Mr. Cooper had tried to assault her, according to a criminal complaint.
When the police arrived, however, Ms. Cooper told an officer that her reports were untrue, and that Mr. Cooper had not touched or assaulted her, the complaint said.
The criminal complaint mentioned two calls, but charged her with only one count.
Ms. Illuzzi told the court that Ms. Cooper had used the police in a way that was “both racially offensive and designed to intimidate,” and that her actions were “something that can’t be ignored.”
Still, the prosecutor said the district attorney’s office was exploring a resolution to the case that would require Ms. Cooper to take responsibility for her actions in court and attend a program to educate her on how harmful they were.
“We hope this process will enlighten, heal and prevent similar harm to our community in the future,” Ms. Illuzzi said.
Judge Nicholas Moyne adjourned the case until Nov. 17 to give Ms. Cooper’s lawyer, Robert Barnes, and prosecutors time to work out the details of an agreement.
“We will hold people who make false and racist 911 calls accountable,” the Manhattan district attorney, Cyrus R. Vance Jr., said in a statement on Wednesday. “Fortunately, no one was injured or killed in the police response to Ms. Cooper’s hoax.”
Mr. Barnes said in July that Ms. Cooper would be found not guilty if the case went to trial and criticized what he called a “cancel culture epidemic.”
“How many lives are we going to destroy over misunderstood, 60-second videos on social media?” he asked. He declined to comment on Wednesday.
Mr. Vance’s decision to charge Ms. Cooper drew mixed reactions from Black community leaders and proponents of overhauling the criminal justice system. He also did not have the support of Mr. Cooper, who has long been a prominent birder in the city and sits on the board of the New York City Audubon Society.
As the episode gained widespread attention across the country, Ms. Cooper, who had been a head of insurance portfolio management at Franklin Templeton, lost her job and was publicly shamed. She also surrendered her dog temporarily to the rescue group from which she had adopted it.
At the time, Mr. Cooper, a 57-year-old Harvard graduate who works in communications, said the consequences and public backlash she had faced were already enough. He did not cooperate with the prosecution’s investigation and said in a statement in July that “bringing her more misery just seems like piling on.”
In an interview on Wednesday, Mr. Cooper declined to answer specific questions about the second 911 call or about Ms. Cooper’s potential plea deal. The encounter in Central Park was “not about Amy Cooper,” he said, but about a larger societal problem.
“My response is very simple: We have to make sure we don’t get distracted,” Mr. Cooper said. “We have a very important goal — and we have to stay focused on it — which is reforming policing, getting systemic change to the structural racism in our society.”
Weeks after the confrontation, New York State lawmakers approved legislation entitling people to “a private right of action” if they believed that someone called the police on them because of their race, gender, nationality or any other protected class. The move was a direct response to the Central Park run-in and other false reports to the police about Black people.
The clash between Mr. Cooper and Ms. Cooper began as he biked to search for birds in a semi-wild section of the park known as the Ramble, where dogs must be leashed. He encountered Ms. Cooper, walking with an unleashed dog, and said in a Facebook post that she refused to put a leash on the dog when asked.
He wrote that he offered the dog treats in an effort to persuade Ms. Cooper to follow the area’s rules. Then, video captures her calling 911 and telling an operator, “I’m in the Ramble, there is a man, African-American. He has a bicycle helmet and he is recording me and threatening me and my dog.”
One day after the incident, Ms. Cooper issued a public apology.
“I reacted emotionally and made false assumptions about his intentions when, in fact, I was the one who was acting inappropriately by not having my dog on a leash,” Ms. Cooper said in the statement. “I am well aware of the pain that misassumptions and insensitive statements about race cause.”
