Considered by ex-prosecutor of France Mr. Thierry Jean-Pierr, Yang Yi-Li's case
should be relative to Yin Ching-Feng's case.
On November 1st, 2003 China Times
indicated (attachment follows) that
ex-prosecutor of France Mr. Thierry Jean-Pierre published a book “Taiwan Connection” revealing
the death of Yin Ching-Feng's nephew Yang Yi-Li was very questionable,
he considered the death of Yang Yi-Li should be relative to Yin Ching-Feng's case.
He also said that in any country their regular police would investigate Yang's case,
especially when Yang’s family had pointed out their questions about the death,
the police should perform deep investigation.
