A white supremacist accused of killing three people near two Kansas Jewish centers says he's ready to plead guilty to all charges to avoid a lengthy trial.

Frazier Glenn Miller told The Associated Press in a phone call from jail on Monday that he doesn't have long to live and wants to have his day in court.

The 74-year-old from Aurora, Missouri, is charged with capital murder in the April 2014 shooting deaths of 69-year-old William Lewis Corporon and his 14-year-old grandson, Reat Griffin Underwood, at the Jewish Community Center of Greater Kansas City in Overland Park, Kansas. He also is accused of killing 53-year-old Terri LaManno at a nearby Jewish retirement home.

Miller told the AP he executed the attacks but wasn't aware none of the victims were Jewish.
