A local court on Thursday heard the case of Huang Yichuan, who allegedly killed two primary school students and injured another boy and woman in a knife attack along Pubei Road in Xuhui district on June 28, thepaper.cn reported. The judgment will be pronounced at a later date.

Huang is considered a schizophrenic and had diminished sense of responsibility at the time of the crime, according to an accrediting body commissioned by local police. But the No. 1 Branch of Shanghai People's Procuratorate accused the defendant of deliberate murder as a way to release his anger from work.

A migrant worker, Huang came to Shanghai on June 6 and purchased a kitchen knife at a supermarket. He targeted students of Shanghai World Foreign Language Primary School after carefully studying the campus. On June 28, he saw students leaving campus and followed them for 130 meters before attacking. Huang was caught by police at the scene.
