According to second-hand reports, Morris does not attend any congregation. Another rumor claims he was disfellowshipped. I think the most likely explanation is that Morris simply doesn't attend any congregation. After three years, someone would have seen him at a Kingdom Hall or convention, but no one has.
Other Governing Body members who were removed in the 1980s were still seen, and that was before the internet. All available evidence points to his inactivity.
