The Committee to Protect Journalists says 19 reporters have disappeared and are still missing after covering the conflict in Syria. On Shepard Smith Reporting, we heard from the parents of one of those missing journalists, Austin Tice, who was kidnapped outside Damascus in August 2012.

Jonathan Hunt reported that we know "precious little" about the freelance journalist's whereabouts. His mother, who used to be in contact daily with her son, has not heard from him in two years.

The family just held a 33rd birthday party for Austin in his absence.

"Austin, please know that we love you and miss you more than words can say. God willing, you'll be back to blow out the candles when you turn 34," said Debra Tice in a message to her son.

Tice, a former U.S. Marine, contributed articles to The Washington Post, McClatchy Newspapers and other news outlets

On Tuesday, ISIS posted a horrific video showing the beheading of American journalist James Foley, who had also gone missing in Syria. Another American journalist, Steven Sotloff, also appeared on the video, with ISIS threatening to kill him next.

Tice's father, Marc, addressing his son's captors, said that Austin is a "good man" and was in Syria for "honorable" reasons.

Hunt said the interview with the parents occurred a few days ago, before news came out of Foley's killing.
