They've also found a cell phone, a computer and camera in a white van that the Federal Bureau of Investigation says he was living in in Alexandria since March.
Over the last several weeks, Hodgkinson spent time at a YMCA near the site of the shooting, sitting with a computer in the lobby or at a table in an exercise area that overlooked the baseball field. They recovered a 7.62 caliber rifle and a 9 mm handgun, which they say Hodgkinson bought legally.
The shooter's widow refused to answer questions about her husband's politics.
In Belleville, residents continued to grapple with the news that one of their own, a man many knew could be quick to anger, but who many said didn't show outward signs of violence, could have committed the mass shooting. "I'm glad they took care that he didn't get to do it again", Schaumleffel said.
Suzanne Hodgkinson talks to members of the media reporters about.
"The gentleman - the shooter - came in and he asked me to put air in his tires", Dauberman said. It was not immediately clear if she thought her husband's move was temporary. Zack Barth, a congressional aide, was shot in the calf, treated and released from a hospital. Two Capitol Police officers sustained relatively minor injuries.

"I know he wasn't happy with the way things were going, the election results and stuff", his brother, Michael Hodgkinson, said in a telephone interview shortly after he received the news Wednesday.
Hodgkinson lived about 100 yards off a rural road in a two-story, seemingly well-kept home with tan vinyl siding.
His Facebook page shows he was a fan of Vermont Sen.
Sanders took to the senate floor on Wednesday, shortly after he was informed the 66 year-old alleged gunman had volunteered with his presidential campaign. Hodgkinson had been angry about income inequality and conservatism.
Amid the torrent of expletives, Dauberman recalled Thursday, Hodgkinson's central point was that the president had messed up the country "more than anyone in the history of this country", Dauberman recalled on Thursday.
ABC News reported that Hodkinson has had run-ins with law enforcement in the past including cases where he discharged shots on his property and a domestic battery case in 2006.
While trying to drive away from that confrontation, the report said, Hodgkinson used a pocket knife to cut a seat belt. According to the court clerk, the charges were dismissed in November of that year.
Later that year, in October 2011, he applauded the Occupy Wall Street protesters in NY and Boston, writing that the demonstrators "are exhausted of our do-nothing Congress doing nothing while our country is going down the tubes". When he went outside, he saw Hodgkinson shooting a rifle into a cornfield.
