BROOKLYN - ? The jury has begun deliberations in the murder trial of George Villanueva, who is accused of killing an NYPD officer last year.

George Villanueva is charged with murder in the death of officer Alain Schaberger. Prosecutors say Villanueva pushed Schaberger down a stairwell when the officer tried to arrest him.

Villanueva's family previously testified in court that it was Schaberger's partner who accidentally nudged him to his death.

While Villanueva is charged with murder, a jury could find him guilty on a lesser charge or acquit him.Man accused of pushing officer to his death pleads not guilty NYPD honors officer killed in line of duty
