James Browning Jr., who led the prosecution of newspaper heiress Patty Hearst during a sensational 1976 trial, has died in Arizona. He was 83.

David Browning says his brother died in the Tucson suburb of Oro Valley on Tuesday after a fall.

James Browning was born in Globe, Arizona, in 1932 and attended law school in San Francisco before becoming the prosecutor in San Mateo County. He was appointed U.S. attorney in Northern California by then-President Richard M. Nixon.

He rose to even greater prominence when he prosecuted the case against Hearst, who was kidnapped by the Symbionese Liberation Army in 1974 and joined their cause. She was charged with bank robbery and other charges, and Browning helped secure her conviction, squaring off with noted defense lawyer F. Lee Bailey.
