Donny Love was convicted of 10 charges in the bombing of a San Diego federal courthouse on May 4, 2008. Among the charges are conspiracy to use weapons of mass destruction.
A woman, who admitted setting off a powerful pipe bomb in front of the Federal Courthouse downtown, will spend 10 years in prison.
Rachelle Lynnette Carlock pleaded guilty to her role in the bombing, which rocked the Edward J. Schwartz Federal Courthouse in May 2008.
Carlock admitted to placing a backpack with three pipe bombs taped together outside the court building and detonating it. The bombs were packed with 110 nails.
The blast shattered the glass front doors of the building at Front Street and Broadway.
The mastermind in the attack, Donny Love Sr., was found guilty on all 10 charges, including the use of weapons of mass destruction.
Love instructed Carlock and Ella Louise Sanders to purchase explosive powder and to steal bomb-making materials. Prosecutors say Love and others constructed pipe bombs at his residence in Menifee in Riverside County.
According to testimony presented at trial, Carlock and Eric Reginald Robinson drove from Love's residence to San Diego with a backpack containing three pipe bombs.
Carlock then detonated the bombs.
After the bombing, Love met with FBI agents and offered to provide information in return for $75,000 in reward money, and help in dismissing two state court convictions for which he was facing six years in prison, prosecutors said.
Carlock has a history of severe mental illness. She was also sentenced to five years of supervised release.
