A federal judge was expected to sentence an Indiana truck driver on Friday for working as an Iraqi spy, ending a trial filled with allegations of mistaken identity and international intrigue.

A jury in January convicted Shaaban Hafiz Ahmad Ali Shaaban on six charges, including acting as an unregistered foreign agent, violating sanctions against Iraq, conspiracy, witness tampering and fraudulently obtaining an Indiana driver's license.

Jurors deadlocked on a seventh charge, which alleged that Shaaban, 53, tried to sell the names of U.S. operatives to Saddam Hussein's government.

Shaaban could face a maximum sentence of 55 years in prison and $1.5 million in fines during Friday's sentencing hearing before U.S. District Court Judge John D. Tinder.

Prosecutors said Shaaban, who is Palestinian, traveled to Baghdad in late 2002 and agreed to sell U.S. intelligence secrets to Iraq for $3 million.

Shaaban was working as a truck driver and living in Greenfield, about 20 miles east of Indianapolis, when he was arrested last March. FBI agents who raided his house that month said they found computer files praising Hussein and an unsigned contract proposing to recruit "human shields" to protect Iraq from the U.S. invasion.

Shaaban represented himself during his 11-day trial, where he argued that he was mistaken for a dead twin brother who worked for the Central Intelligence Agency.
