US NAVY GETTY

The Navy is investigating whether two members of the Navy's elite SEAL Team Six killed an Army Green Beret in Mali in June, a US official told CNN Sunday.

Naval Criminal Investigative Service spokesman Ed Buice confirmed the NCIS investigation into the death of Army Staff Sgt. Logan J. Melgar.

Melgar was a Special Forces Engineer Sergeant, the U.S. Army Special Command said. Military officials told CNN that a military examiner ruled Melgar's death while on assignment in the African nation of Mali as a homicide.

A US official told CNN jurisdiction for the investigation shifted from the Army investigation service to the Navy in September. The official said the transfer of jurisdiction indicates that Navy personnel are subjects of the investigation.

The New York Times was the first to report that two members of SEAL Team Six were under investigation for Melgar's death, saying his death was caused by strangulation at a US government compound near the American embassy in Bamako, the capital.

Michelle Melgar, the victim's wife, has been notified her husband's manner of death was a homicide, the official said.

She told CNN: "I ask for privacy during this time -- I hope that you will allow me to tell my story when I'm ready. I knew him best -- he was my best friend. It's all so new -- I'm sorry."

Melgar, a native of Lubbock, Texas, enlisted in the US Army in 2012 and began Special Forces training in 2013, according to the US Army Special Command statement. He served two deployments to Afghanistan.

The report of the mysterious death and resulting homicide investigation comes as the US undergoes heightened scrutiny about its military role Africa following the death of four US service members in Niger earlier this month.

Melgar was a member of the 3rd Special Forces Group, which is the primary unit responsible for Army special operations in northwest Africa, including Mali and Niger. The four American soldiers killed in Niger earlier this month were part of the same group.
