“It’s very rare in our community to have this kind of violence,” State Assembly Lester Chang toldABC 7. “Back home in China, they’re Fukanese. They live in close quarters, close compact quarters so they’re used to it. Something had to trigger” for the suspect “to cross that moral line.”

Adding to the tragedy, Ye’s 9-year-old son watched the gruesome attack unfold, local leaders said, per the outlet.

“The roommate likely got the call from the perpetrator to say come get my son,” New York State Senator Iwen Chu said, per ABC 7.

“We all have to pray for these young kids,” Chang added, per the outlet. “These two young kids fighting for their lives. And I can only imagine what the father has to go through.”
