Army officials have told the parents of Sgt. Matt Maupin that some of the Iraqis believed to be responsible for their son’s capture four years ago are in custody, the Cincinnati Enquirer reported Thursday.

“I know that there are at least two who are supposed to be put on trial, if they haven’t been already,” Keith Maupin, father of the Ohio soldier, told the Enquirer. Maupin’s remains were found March 20 in Iraq by U.S. soldiers, nearly four years after he was captured in a convoy attack near the Baghdad airport.

Keith Maupin and the soldier’s mother, Carolyn Maupin, left Cincinnati on Wednesday for Washington, where they will have a full day of briefings from Pentagon officials on their son’s disappearance, the paper reported.

The soldier’s father told the Enquirer that he expected to learn more Thursday about the Iraqi insurgents believed to be responsible for the then-20-year-old Army reservist’s capture; and more about how and when their son died.

They also will have a video conference with soldiers from the 1st battalion, 21st Infantry Regiment who discovered Maupin’s remains on March 20 northwest of Baghdad, working on a tip from an Iraqi civilian, the Enquirer reported.

Keith Maupin said he was told by Army officials soon after the remains were discovered that some of those believed responsible for their son’s capture and death had been detained, the Enquirer reported.

The Maupins plan to return to Cincinnati on Friday to continue with planning for their son’s visitation and funeral, the paper wrote.
