Zheng Yibao was ordered by Stuart Owens to investigate the Miracle in Shanghai in 2011. He had an uncle who was dying, but alive because of Miracle Day. After investigating the Three Families' base in Shanghai, he jumped off a high building, resulting in him becoming Category 1, the closest thing to death after Miracle Day. (TV: The Middle Men)

His suicide was presumably a result of seeing the Blessing, which would cause people who were hiding something "vile" to kill themselves. (TV: The Gathering) Zheng presumably died when the Miracle was negated. (TV: The Blood Line)
