The last of three people accused of blowing up a pipe bomb out front of a federal courthouse in May 2008 entered a guilty plea on Tuesday and is to serve 30 years in jail. 

Rachel Lynn Carlock entered a guilty plea to one count of possession and use of a destructive device in order to carry out a violent crime. According to the nature of her charge, she is to be sentenced to serve at least 30 years in jail. She is to receive her sentencing on March 9.

She said that she was guilty for buying 2 pounds of explosives in April 2008 and then creating a couple bombs, as stated in the plea agreement. 

Carlock also said she had put three pipe bombs in front of the courthouse located on Front Street early in the morning on May 4.

No one was hurt when the bombs blew up, which projected nails and shrapnel for a couple blocks. The reasoning behind the bombings are not yet known. 

Two others, Ella Louise Sanders and Eric Robinson, had admitted to the crime earlier than Carlock and were also waiting to receive their punishment.  

Carlock’s case was set back for a couple moths when she was sent to be a patient at a federal psychiatric facility after it was clear that she was not able to go through trial.  After being a patient there, she returned to San Diego and her case was picked back up again.

“I was in a desperate situation at the time,” Carlock said to District Judge Margaret McKeown. “Really unhappy. It wasn’t my own will to do it. I was forced to do it. I apologize for doing it.”
