Aug. 9, 2013 -- "The King of Queens" star Leah Remini, who made headlines in July when she left the Church of Scientology, has taken her confrontation with the controversial church to a new level by filing a missing person report on the church's leader's wife, which has now been dismissed by police.
Remini, 43, announced last month that she will be writing a tell-all memoir that will touch on her time with the Church of Scientology. The actress has been very public about her decision to leave the church.
"It will include my experiences, everything that's taboo to talk about," Remini, 43, told Us Weekly magazine at a charity event July 27.
ABC News has confirmed that Remini has now filed a missing persons report with the Los Angeles police department on her friend Shelly Miscavige, the wife of the church's ecclesiastical leader, David Miscavige. Shelly Miscavige has not been seen in public in six years, according to the LA Times.
Shelly Miscavige's whereabouts have been a source of feverish speculation among the Church of Scientology's many critics.
"She was his wife, she was his close advisor, she would have been an integral part in every aspect of his life," said Janet Reitman, the author of "Inside Scientology." "So her absence is quite noted, particularly by people who have been in the upper echelons of the church, the executives."
Hours after Remini filed that missing persons report, the LAPD told ABC News that "the case is closed," and said reports that Shelly Miscavige is missing are "unfounded."
"This ill-advised, ludicrous self-promotion and the media inquiries it generated caused an inexcusable distraction for the LAPD," the church said in a statement released today. "The entire episode was nothing more than a publicity stunt for Ms. Remini."
Reitman said that she believes the church must see Remini as a challenge.
"Oh my God, of course they're worried about her," she said. "Leah Remini I think really, really believed in this, so I think she feels quite betrayed. Or she feels very angry -- both."
The LAPD tells ABC News that Shelly Miscavige is alive.
"Our missing persons detectives have met with the alleged missing person within the past two days. We consider this case closed," police said.
The LAPD also said that this is not the first time they've received a missing persons report on Shelly Miscavige.
Remini joined the church at age 7 and served for one year in its elite "Sea Org" religious order. She was also friends with some of Scientology's most high-profile members, including Tom Cruise.
Reitman's book "Inside Scientology" is now being released in paperback.
