The 88-year-old hatemonger is accused of shooting and killing security guard Stephen Johns who held the door to the U.S. Holocaust Memorial Museum open for him on June 10. The computer was found in a search of the Annapolis, Md., home he shared with his son, the Washington Post reported.
In a warrant affidavit requesting a more thorough search of the computer, FBI agents mentioned the pornography but did not disclose the type or extent, the Post reported.
Authorities took more than 30 items from the Annapolis apartment, including disks, a handwritten will, a rifle, ammunition and a "painting of what appears to be Hitler and Jesus," FBI Special Agent Christy Shaffer said in a search warrant return.
In von Brunn's car, which was parked outside the museum during the shooting, FBI agents recovered live .22-caliber ammunition and business cards advertising von Brunn's Web site and another site that claims the Navy's USS Liberty was "brutally attacked" by Israeli forces in 1967, officials said. Among other items in the car were glass fragments, matchboxes and a disabled parking permit, according to the Associated Press.
Von Brunn, who was shot in the face by guards who returned fire, remains hospitalized. FBI officials have said he is likely to survive.
A funeral will be held Friday for Johns. The viewing will begin at 10 a.m., followed by an 11 a.m. funeral service at Emmanuel Baptist Church in southeast Washington, according to a church representative.
Johns, who lived in Temple Hills, Md., had worked at the museum for six years. He had an 11-year-old son and had recently celebrated his first wedding anniversary with his second wife.
