LA-area teenage brothers killed; uncle captured in China

Authorities believe a Los Angeles-area man killed his teenage nephews before fleeing to China because he was upset his wife wanted a divorce.

The Los Angeles County Sheriff's Department says a woman called 911 on Friday reporting she had found her two sons suffering from head trauma in their Arcadia home. The 15- and 16-year-old boys were pronounced dead when police arrived.

Investigators believe the boys' uncle, 44-year-old Deyun Shi, is responsible and say he fled to China. FBI spokeswoman Laura Eimiller says Shi was taken into custody in Hong Kong.

On Thursday night, investigators say Shi assaulted his wife after learning she wanted a divorce. Shi's wife is the sister of the dead teens' father.

Investigators believe the boys were killed while their parents visited Shi's wife in the hospital.
