A decade after leaving her family behind to flee North Korea, the defector was overwhelmed with excitement when she spoke to her 22-year-old son on the phone for the first time in May after he too escaped into China. While speaking to him again on the phone days later, however, she listened in horror as the safe house where her son and four other North Korean escapees were hiding was raided by Chinese authorities. The woman, now living in South Korea, said she heard rumours her son is being held in a Chinese prison near the North Korean border, but has had no official news of his whereabouts.
