A day after Officer Peter Liang was convicted of manslaughter in the shooting death of Akai Gurley, his partner has also been fired by the NYPD, reports said.

Probationary officer Shaun Landau had been on modified duty since November 2014, when he and Liang were on a routine patrol in Brooklyn that resulted in the shooting death of an unarmed man, Gurley. They were patrolling through a darkened stairwell at the Louis Pink Houses in East New York, Brooklyn when Liang fired a shot that killed Gurley, 28. Gurley was walking down the stairs because the elevator was broken, FOX News reported. 

After Liang was convicted on manslaughter and official misconducton on Thursday, the family of Gurley called for Landau to be fired, according to NBC New York.

Landau testified under immunity from the prosecution during the trial of his partner. Neither one of the officers tried to help Gurley. They both told a State Supreme Court jury in Brooklyn that they did not feel qualified to perform CPR.

Testimony showed that neither partner called a supervisor for at least four minutes after the shooting, according to the New York Times.

NBC New York reported that Liang left the stairwell after the shooting and argued with Landau on who should call a sergeant. They went back to the stairwell and found the woman Gurley was with calling 911.

Liang is the first NYPD cop convicted of an on-duty death since 2005, according to NBC New York. He was later fired after the trial concluded, and faces up to 15 years in prison. He will be sentenced on April 14.
