Shelly Miscavige's Father-In-Law Ron Tells All On Her Alleged Disappearance

Scientology chief David Miscavige's wife Shelly has been mysteriously absent from public life for years.

Now, the Church is getting bashed over the issue, as David's estranged father Ron has spoken to Australia's 60 Minutes.

Rumors have flown that Shelly was forced to stay in Scientology, a claim the Church has vehemently denied.

But ex- Scientologist Ron said he may be unsure of Shelly's whereabouts forever.

He believes "she'll never be free."

Ron also thinks Shelly not being by the public in more than a decade shows the Church's "lack of conscience."

He joined the Church of Scientology in 1970 and worked in its "Sea Org" group for 42 years.

But Ron left the religion in 2012 and he's been estranged from son David, Scientology's top boss, for years.

Ron isn't the first former Church member to reference Shelly's alleged disappearance.

Leah Remini was so concerned about Shelly's whereabouts that she filed a "missing person" report on the leader's wife in 2013 with the Los Angeles Police Department.

The actress said she was confused when Shelly didn't show up at famous member Tom Cruise's wedding to Katie Holmes in 2007.

Cops investigated and concluded that the "missing person" report was unfounded.

Still, Shelly, who used to always be by David's side, has been elusive.

Remini, who has slammed the church on her TV show Scientology and the Afermath, has fumed, "You can't just do what you want with a human being."

Scientology has denied anything's amiss with Shelly, saying that she continues to work for the religious group behind the scenes.

The Church has charged, "Remini has been stalking her with repeated sham claims."

Scientology has called Ron's 60 Minutes interview "deceitful" and the entire segment "yellow journalism" in a blog post.
