WASHINGTON -- Two members of SEAL Team 6 are "being looked at" in the death of an Army Green Beret in Mali, CBS News confirms.

In June, Staff Sgt. Logan J. Melgar, a 34-year-old veteran, was found dead in his embassy housing in Bamako, The New York Times reports. His superiors immediately suspected foul play.

An autopsy ruled Melgar's death a homicide. The two SEALS under suspicion were involved in an altercation with him, CBS News national security correspondent David Martin reports.

No one has been charged in Melgar's death, and the Times reports that the military medical examiner said his death was caused by strangulation. The Army's Criminal Investigation Command investigated the case for months before handing it off to the Naval Criminal Investigative Service.

The agency took over the case on Sept. 25, CBS News confirms.

After the incident, the two unidentified SEALs were flown out of Mali and placed on administrative leave, the Times reports. Melgar and several other Special Operations forces were assigned to the West African nation to help with training and counterterrorism missions, the newspaper adds.
