A man extradited from Hawaii to face charges in a San Diego cold case has admitted to his wife's killing.
Anthony Simoneau, 46, entered a guilty plea Thursday to one count of voluntary manslaughter in the murder of his wife, Fumiko Ogawa.
The plea agreement says Simoneau killed Ogawa because of a "sudden quarrel in the heat of passion that resulted from an argument in which you were provoked."
Ogawa, 41, was last seen in 2007, and her body was unearthed in the Anza Borrego Desert four years later.
Family members in Japan reported her missing, not her husband, officials said.
Under the plea agreement, Simoneau will be sentenced to 11 years behind bars minus time served when he's sentenced on April 30. He will then be placed on parole for up to seven years.
He also gives up any rights to Ogawa's remains.
