PITTSFIELD, Massachusetts — A Massachusetts survivor of clergy sex abuse says he will stop eating until the Vatican acknowledges receipt of messages from several families of victims he was assured would be sent to Pope Francis.

Olan Horne, one of the first survivors to go public about abuse in the Boston Archdiocese and a longtime advocate for families affected by abuse, tells The Berkshire Eagle his hunger strike will start midnight Wednesday. A summit on abuse starts Thursday in Rome.

The 59-year-old Chester man says last fall he gathered messages from Massachusetts families to send to Francis. He delivered them to Boston Cardinal Sean O’Malley and was told they would go to the pope.

An O’Malley spokesman didn’t respond to the Eagle’s requests to confirm whether the messages reached Francis.
