Wong Wai-yin's wife feared the worst after reading his short farewell letter.
"I am sorry and thanks for accompanying me throughout the years," the hand-written note found on a desk at their home read. "I'm sorry that I can't walk with you anymore. ... Please take care of yourselves."
Wong, 30, an unemployed dock mechanic facing criminal charges relating to his participation in the protests that roiled Hong Kong last year, had scribbled his message to his wife and his mother on a page torn from a notebook.
