Criminal charges will be unsealed against a rookie police officer who fired into a darkened stairwell at a Brooklyn housing complex, accidentally killing a man who had been waiting for an elevator.

A lawyer says Officer Peter Liang was indicted by a grand jury in the November shooting death of 28-year-old Akai Gurley. It wasn't clear what charges the grand jury considered. He could face a misdemeanor official misconduct, or manslaughter, a felony. A lawyer for Gurley's family says the officer is expected in court Wednesday afternoon.

The case was closely watched following the mass protests and calls for reform of the grand jury system nationwide after a Staten Island grand jury's refusal to indict a white police officer in the chokehold death of Eric Garner.
