SACRAMENTO (AP) — The man accused of planning a Christmas Day bombing and shooting attack at San Francisco’s Pier 39 pled guilty Monday.

Everitt Aaron Jameson pled guilty Monday to attempting to aid a terrorist organization under a plea deal with federal prosecutors.

Prosecutors say Jameson, a former tow-truck driver from Modesto, California, told the undercover federal agents that he planned to use pipe bombs to channel victims into part of Pier 39 so he could shoot them.

Prosecutors are dropping a second charge of distributing bomb-making information under the plea agreement.

Each charge carries a maximum penalty of 20 years in prison.

Defense attorney Charles Lee says his client was having second thoughts and didn’t actually take steps to carry out the plot.

The 26-year-old tow truck driver specifically named Pier 39 as his target because “he has been there before and knew that it was a heavily crowded area,” according to FBI documents.

Back in January, Jameson pleaded not guilty to distributing bomb-making information and attempting to aid a terrorist organization.
