Family of Austin Tice says 'a significant source' indicates he is alive, being 'treated well'

The family of Austin Tice, the American freelance journalist and Marine Corps veteran who was kidnapped while reporting in Syria in 2012, said it has been in contact with a "significant source" that confirmed he is alive and well.

"We have from a significant source that has already been vetted all over our government that Austin Tice is alive, Austin Tice is treated well, and there is no doubt about that," said Tice's mother, Debra.

National security adviser Jake Sullivan met with the family of Tice, who has been missing for more than 12 years after he was abducted on Aug. 13, 2012, at the White House on Friday.

“Jake Sullivan has regularly met with the families of wrongfully detained Americans,” White House press secretary Karine Jean-Pierre said following the meeting. “We're going to continue to make sure that we get Americans who are wrongfully detained, Americans home to their families."

The Biden administration has successfully brought 75 unjustly detained Americans back to the United States.

Although reporters asked for more information about the source, the Tice family said it could not share more, claiming the U.S. government is restricting it from doing so for reasons the family does not understand. ABC News reached out to the family.

However, Tice's father, Marc, said the family is "working toward" making more information public and that the source is "very different" from others who had given the family false hope in the past.

"We are confident in that this information is fresh," he said. "It indicates as late as earlier this year that Austin is alive and being cared for."

The U.S. government has continuously operated under the assumption that, despite his lengthy captivity and limited intelligence about his whereabouts, Tice is still alive. But its belief is primarily founded on a lack of evidence to suggest he is dead rather than evidence proving he is alive, according to multiple sources.

Questions about who exactly is holding Tice have cropped up over the past few years. The Biden administration has been careful with its wording on this, issuing statements saying that "we know with certainty that he has been held by the Government of Syria" because officials believe it is possible Tice is now in the custody of another group. However, the administration still believes the Syrian government has the power to bring about his release.

If the new source does have legitimate insight into Tice's conditions, it stands to reason the source would likely also have information about whatever entity is holding him in custody, which could provide clues to his exact location.

The Syrian government has never publicly acknowledged playing any part in Tice's disappearance, but during talks under the Trump administration, Syrian officials said they would provide proof of life in exchange for the United States fulfilling sweeping demands, according to officials familiar with the private negotiations. The Trump administration did not comply, and the Syrian government did not hand over any information about Tice.

The FBI has offered a reward of up to $1 million for information leading to the safe location, recovery, and return of Tice.
