Kenneth Conley Tattoo Image Released As FBI Manhunt For Chicago Prison Break Fugitive Goes National

Kenneth Conley has been on the lam for more than two weeks since his daring escape from a high-rise downtown Chicago prison, and now the Federal Bureau of Investigations is taking its manhunt nationwide.

New images released by the FBI include the convicted bank robber's upper arm tattoo of a devil. FBI Special Agent Joan Hyde told the Associated Press the tattoo "would be very hard to remove or disguise."

Conley's disappearance has left investigators grasping at straws, with CBS Chicago reporting in a broadcast that feds are aware the fugitive bank robber has "been known to travel." Beyond that, investigators are "banking on a tip" that someone will call with a sighting of Conley.

Police scoped out a Tinley Park, Ill. home where Conley's mother lives, with investigators initially focusing on the Chicagoland area in the days after the escape.

Conley escaped from lockup at the Metropolitan Correctional Center along with Joseph Banks on Dec. 18. The breakout stunned prison officials after it was learned the men busted out concrete around the window, employed decoy window bars and scaled 15 stories down the side of the building using a rope made of knotted bed sheets.

After the escape, the men caught a cab and were thought to be traveling together as they fled the area, according to NBC Chicago. Banks was captured Dec. 20 in Lincoln Park. Escape charges against Banks, who already faces up to 80 years in prison on a previous bank robbery conviction, were dropped on Thursday.

The FBI has posted a $50,000 reward for information leading to Conley's capture.

Anyone who sees Conley is being urged to call the FBI's Chicago office at 312-421-6700.
