NORFOLK, Va. (AP) — A hearing is under way in a military court on Naval Station Norfolk to review the case against a U.S. Marine and a Navy SEAL who are charged in the 2017 hazing death of a U.S. Green Beret in Africa.

Defense attorneys for Navy SEAL Tony DeDolph and Marine Mario Madera-Rodriguez told a judge Monday morning they plan to call several witnesses.

The Article 32 hearing could lead to courts-martial proceedings later.

DeDolph and Madera-Rodriguez are among four U.S. servicemen charged in the strangulation death of Army Staff Sgt. Logan Melgar in Mali.

Marine Staff Sgt. Kevin Maxwell Jr. and SEAL Adam Matthews pleaded guilty to lesser charges and were sentenced to prison.

Matthews testified in May that Melgar’s death was as a botched attempt to “embarrass” him over perceived “slights.”
