Teen, 16, charged with murder in fatal shooting of NYC mom inside her condo building

A 16-year-old boy was arrested and charged with murder Thursday more than a week after a Big Apple mother was fatally shot in front of her family during a violent robbery, cops said.

The teen, who was not identified, was also charged with burglary, robbery and criminal possession of a weapon in the shooting death of 57-year-old home health aide Ying Zhu Liu, police said.

Another two young suspects are still being sought, sources told The Post.

Liu was killed inside the eighth-floor hallway of her lower Manhattan building just after 11 p.m. on Sept. 9.

Authorities said last week two suspects donning black ski masks followed the victim’s 61-year-old husband into the building and into the elevator where they tried to rob him.

When the son witnessed the robbery in progress on the eighth floor, he attempted to intervene, but was pistol whipped by one of the suspects, according to sources.

Liu then heard the struggle and came out with a stick to confront the perps before she was shot in the face.

The robbers allegedly grabbed Liu’s husband’s cell phone before they fled.

“It’s all surreal,” Liu’s distraught 32-year-old son, Lin Rong Yan, told The Post last week. “I feel only sadness right now.”
