California inmates in separate prisons killed in attacks

Sidney Kang, 31, died Thursday after he was attacked around 10 a.m. in a recreational yard at Kern Valley State Prison in Delano. He was treated for his injuries at the prison but died a short time later. 

Kang had been incarcerated since 2014 and was serving a 14-year sentence for assault with force likely to produce great bodily injury in Los Angeles County, officials said. He had a previous serious felony conviction and it was his second strike.
