More than a week after a New York mother was shot and killed in front of her family during a robbery, a 16-year-old boy was arrested Thursday and charged with murder, according to the New York Police Department.
The teen, whose identity has not been released, was also charged with theft, robbery and unlawful possession of a weapon in the shooting death of 57-year-old home care worker Ying Chu Liu, police said.
Sources said two other young suspects were still being sought.
Liu was murdered in the hallway of her eighth-floor building in lower Manhattan on September 9th, just after 11pm.
Authorities said last week that two suspects wearing black balaclavas followed the victim's 61-year-old husband into the building and into an elevator where they attempted to rob him.
Sources said the son witnessed the robbery taking place on the eighth floor and tried to intervene, but was hit with a handgun by one of the suspects.

Liu heard the sounds of a struggle and tried to confront the attacker with a stick, but was shot in the face.
The robbers allegedly stole Liu's husband's mobile phone before fleeing.
“It all seems surreal,” Liu's distraught 32-year-old son, Lin Rong Yan, told The Washington Post last week. “Right now I just feel sadness.”
