BROOKLYN - The NYPD fired a second officer in connection with Peter Liang's conviction Thursday of manslaughter in the 2014 death of an unarmed East New York man during a routine patrol.

Liang's partner, Shaun Landau, was fired Friday. As News 12 has previously reported, the department cut Liang within minutes of his conviction.

Liang shot and killed the unarmed Akai Gurley in a dark Pink Houses stairwell two years ago. Gurley's family applauded the decision to fire Landau Friday.

Liang and Landau were on a so-called vertical patrol at the building when Liang fired his gun in an unlit stairwell. Liang's defense argued that he fired accidentally after a noise surprised him. The bullet ricocheted off a wall and fatally struck Gurley, a father of two. 

Prosecutors argued that Liang acted recklessly when he fired his service weapon. 

Gurley's family has called for an end to vertical patrols, which send officers to patrol public housing buildings floor by floor in high-crime neighborhoods. Recently, two NYPD officers survived being shot in the Bronx on one such patrol.

Liang faces up to 15 years in prison at his sentencing on April 14. His defense attorney announced Thursday that he would appeal the decision.

Legal experts tell News 12 that the defense may have a case, but nevertheless could have a hard time overturning the verdict.
