The Army has received and is reviewing an initial report on the investigation into Sgt. Bowe Bergdahl's disappearance and capture in Afghanistan.

Bergdahl allegedly walked off his remote post in Afghanistan and was then captured by the Taliban. He was in captivity for five years before he was freed May 31 as part of a controversial exchange with the Taliban for five militants who were detained at Guantanamo Bay, Cuba.

"This will be a lengthy process conducted in accordance with applicable laws, regulation and policy," Army spokeswoman Lt. Col. Alayne Conway said in a statement Friday. "We recognize the importance of the media and the public understanding of our investigative process and look forward to future discussions on this issue."

The Army is focused on making sure its process is "thorough, factually accurate, impartial and legally correct," Conway said.

"At this time it would be inappropriate to speculate on the potential results or the amount of time the review process will take to complete," she said.

Maj. Gen. Kenneth Dahl led the Army's investigation. Bergdahl is assigned to Joint Base San Antonio-Fort Sam Houston, Texas.
