Yu Yao, 23, died Friday at New York Hospital Queens, after being on life support for nearly a week.

Investigators say she was attacked in Flushing the night of May 16.

State Assemblywoman Grace Meng says she's learned through witnesses and surveillance video that several people walked by the attack and did nothing.

"At least three people were seen to have watched the beating and the assault and did not scream, did not yell for help, did not do anything. I myself have been really disappointed and angry," Meng said.

Carlos Salazar Cruz, 28, was arrested after a witness called 911.

Charges against him are expected to be upgraded following Yao's death.

Yao arrived in New York on a student visa from China two months ago.
