Bronx District Attorney Darcel Clark is asking for a grand jury to investigate the fatal shooting of a 66-year-old woman.
Deborah Danner died after being shot by Sergeant Hugh Barry in her apartment on October 18.
According to police, Barry convinced her to drop a pair of scissors she was holding, but police say he shot her after she grabbed a bat and tried to hit him with it.
"I have pledged to the people of the Bronx to conduct a thorough, fair investigation into this matter and I believe that presenting the evidence to a grand jury will best accomplish that goal. It is important to determine exactly what happened in this tragic incident," Clark said, in part, in a statement.
The case has sparked discussions on the treatment of the mentally ill by police.
Police say Danner suffered from schizophrenia, and they say officers were called to her apartment several times for prior incidents.
Danner’s family called for investigations in the days after the shooting.
"The New York City Police Department has once again failed to properly respond to deal with mentally ill patients without resorting to deadly physical force," her sister, Jennifer Danner, said on October 19.
The incident was also met with criticism by the mayor and police commissioner. Mayor Bill de Blasio called the shooting "unacceptable," and Police Commissioner James O'Neill said, "What is clear in this one incident, we failed."
Those statements drew the ire of Sergeants Benevolent Association President Ed Mullins. In a statement on October 22, Mullins said, "Commissioner O'Neill's actions can only be explained as having a lack of courage to stand up against a failing Mayor."
Barry was equipped with a Taser, but he did not use it.
He has been placed on modified duty, and was stripped of his badge and gun.
