CLEVELAND -- The Marine Corps Thursday publicly confirmed for the first time that the insurgents responsible for the death of six Brook Park Marines have been taken into custody.

Two separate attacks in Iraq last August killed a total of 20 men from the 3rd Battalion 25th Marines. The families of the fallen Marines have been waiting to get answers about what really happened.

The Marine Corps continues to look for insurgents, but as recently as two weeks ago, Marines were searching for insurgents in Haqlaniya, Iraq, whom they suspect were connected to the Aug. 1 killings of six Marine snipers, reported NewsChannel5's Adam Shapiro.

The Marines took 19-year-old Saba Riya into custody, but have been unable to tell NewsChannel5 what has happened to him since his capture.

The Marines confirmed that the insurgents who may have been responsible for the August ambush were taken into custody soon after the attack, but the status of those prisoners is classified.

This was revealed during a Wednesday briefing with Rep. Dennis Kucinich, who spoke exclusively about it to NewsChannel5.

"We are quite sure after looking at all the reports that no betrayal occurred, and that the unfortunate deaths of those Marines was not due to any infiltration of leak of information from Iraqi defense forces," said Kucinich.

Some of the Marines returning from Iraq told the families of the fallen that their loved ones may have been betrayed. On Aug. 12, Marine Commandant Gen. Michael Hagee promised families of the fallen that those allegations would be investigated.

With that investigation now complete, Kucinich said the Marine Corps has ruled out any kind of betrayal in the attack which killed the six snipers and the tragedy two days later that cost 14 more 3/25 Marines their lives.

The Marine Corps said the 14 were on a mission that wasn't connected to the snipers' ambush, and Kucinich said what he learned in the classified briefing confirmed it.

"I carry this tragedy in my own heart. I know how the families feel, and I am there as a representative to get every answer possible," said Kucinich.

Kucinich is asking the Marine Corps to meet privately with the families of the fallen to answer questions and share results of the investigation with them.
