The case against the man charged with planting pipe bombs at the two party headquarters is being challenged as a wrongful prosecution built on a shaky confession.

• No one was arrested for five years, until a news report named a different suspect based on software that matches people by how they walk.
• That report pointed to a woman now working on a security detail at the CIA and said she failed a polygraph about the bombings.
• The current defendant was arrested almost immediately afterward, and the government says he confessed.
• His family says he is autistic, and people with autism are far more likely to confess to crimes they did not commit under pressure.
• The sequence of events looks less like an investigation and more like a story assembled to fit.

Outlook: Expect the confession and the polygraph claim to become the central fight as the case moves forward.
