The base's 36th Wing said in a news release today that search-and-recovery efforts that began after Master Sgt Greg Ramos was reported missing around midnight November 21 have produced no signs of him.
Authorities were alerted to a missing swimmer off Tarague Beach. They continued their search through Saturday.
Brig Gen Douglas Cox, the 36th Wing commander, said the guard is "extremely saddened" and he offered prayers for Ramos' family and friends. He cautioned that while "the waters off Guam are beautiful and inviting," they can be dangerous.
