The suspect was just in the Bay Area Sunday night, attending the Raiders - Cowboys game with his father.

According to FBI documents, Jameson picked the Pier 39 location because he "had been there before and knew it was a heavily crowded area." He added that it would be easy to "funnel" people into an area where he could inflict casualties.
In a statement this afternoon, Acting Mayor London Breed said in part, "San Francisco is a city that proudly champions democracy... freedom... and liberty... Sadly, that makes our home a target."
Jameson reportedly said he was inspired by the New York terror attack on Oct. 31, when a man drove into a crowd and killed eight people, and the deadly 2015 shooting in San Bernardino.
The documents also say Jameson was posting and liking pro-ISIS and pro-terrorism content on Facebook.
And according to the documents, the suspect was discharged from the Marine Corps. He had prior military experience with a "sharpshooter" rifle qualification and expertise with rifle marksmanship.
Officials say Jameson was talking to an undercover FBI agent. They add that he was arrested earlier this week and a search warrant was executed at his Modesto home. Several firearms were found, along with fireworks.
ABC7 News contacted officials at Pier 39 to ask for a response, they say they did not know about this plot.
