Parents of ISIS Hostage Say They Cried When Raid to Kill Group's Leader Was Named for Her

The Muellers still have so many unanswered questions about Kayla’s final days.

The parents of the American hostage murdered by ISIS are talking to Inside Edition after the operation to kill the leader of the terrorist organization was named for her. 

Kayla Mueller went to Syria to help refugees in 2013. While there, she was kidnapped during a tour of a Doctors Without Boarders hospital, and she was repeatedly raped and tortured by ISIS members. 

ISIS leader Abu Bakr al-Baghdadi took Kayla as his personal sex slave. 

“They were handcuffed, they slept in handcuffs at night,” her father, Carl Mueller, said of Kayla's time there. “The wife of Abu Bakr would tell Kayla, ‘Make yourself ready, he is coming’ to rape her. We know that from the girls that were held with her.” 

ISIS later released a proof of life video of Kayla, in which she says, "I’ve been here too long and I’ve been very sick and it's very terrifying here."

Then came the news her parents prayed would never come: She was killed. Her body has not yet been found. 

Then, President Trump announced al-Baghdadi had died in a raid of northwestern Syria,a raid that had been code-named for Kayla. When they learned that detail, “tears” is “the best way to explain" the Muellers' reaction, they said.

The Muellers said they watched Sunday morning as Trump reminded the world how their daughter had been tortured at the hands of al-Baghdadi.

"It is an honor for us to have Kayla remembered so much but I don’t want to forget the rest of all of the people who suffered so much too," her mother, Marsha Mueller, said. 

After her daughter's kidnapping, Marsha said, she would go into Kayla’s empty bedroom to write letters for her to read upon her return.

Now, the Mueller’s still have so many unanswered questions about Kayla’s final days. 

"Our true goal is to find Kayla, to find out what truly happened to Kayla and to bring her home," Marsha added.
