The police officers encountered the man, whose identity the police have not released, around 12:20 p.m.at an apartment building at 1370 New York Avenue in East Flatbush. She told them he had mental health issues but was not armed.
According to police, Jeune's mother called 911 due to her son's erratic behavior and let the officers inside her residence when they arrived.
One of the officers tried subduing Jeune with a taser, hitting him once in the chest and once in the arm, but it had no effect on him, according to the NY Daily News, and Jeune kept "moving forward".
It was then that shots were fired, killing Jeune. Jeune died at the scene, and Monahan described the shooting as unfolding "in seconds".
But Jeune continued to advance on officers, Monahan said.More news: Serge Aurier reportedly agrees terms with Manchester United
