The Army identified the two soldiers who apparently drowned Friday off Kualoa Beach Park.

They are:

>> Sgt. John H. Nguyen, 27, assigned to Charlie Company, 715th Military Intelligence Battalion, 500th Military Intelligence Brigade, Schofield Barracks.

>> Pvt. Tuan M. Huynh, 26, assigned to Headquarters, Sustainment Automation Support Management Office, 45th Special Troops Battalion, 45th Sustainment Brigade, Schofield Barracks.

Nguyen joined the Army in 2007 and is originally from Clemson, S.C., according to U.S. Army Pacific, based at Fort Shafter.

A third soldier was injured returning to Kualoa Beach Park from Mokolii island, also known as Chinaman’s Hat, and is being treated at a nearby hospital. 

An investigation is being conducted to determine the cause of death, the Army said Sunday.
