A woman admitted her role in the bombing of the San Diego federal courthouse.
Ella Sanders entered a guilty plea in federal court Friday to one count of possession and use of a destructive device to commit a crime of violence.
Sanders and Eric Robinson were accused of building numerous pipe bombs and setting off an explosion at the downtown Edward J. Schwartz Federal Courthouse on May 4. Sanders also admitted she helped build pipe bombs for the explosion April 25 at a FedEx distribution center in Webster.
Robinson pleaded guilty in connection to the case in September. A third defendant, Rachelle Carlock, still faces charges in connection with the case.
No one was injured in either bombing.
Sanders could face a lengthy prison sentence when she is sentenced in August 2009.
