REHOVOT, Israel (AP) — His partners tout him as a successful case of rehabilitation and second chances: When he was 20 years old, Harel Hershtik planned and executed a murder. Today, he is the brains behind an Israeli health-tech startup, poised to make millions of dollars with the backing of prominent public figures and deep-pocket investors. But with his company set to go public, Hershtik’s past is coming under new scrutiny, raising questions about whether someone who took a person’s life deserves to rehabilitate his own to such an extent. It also tells an astounding tale of a life derailed and improbably set back on track.
