New claims say the FBI and prosecutors buried eyewitness accounts that Timothy McVeigh had a partner at the Oklahoma City bombing, which is bad news for anyone who trusts the official story that he acted alone.

• A survivor who lost her mother and two children in the blast told the FBI she watched McVeigh get out of the truck along with a second man who ran off.
• At trial, the FBI brushed her off as too traumatized to be a reliable witness.
• Dozens of other people also reported seeing McVeigh downtown that morning with other people.
• Prosecutors never called a single witness who could put McVeigh at the scene, because every one of them also saw him with someone else.

Outlook: Expect more pressure on the FBI to release files and explain why the lone-bomber story was pushed despite the eyewitnesses.
