Police entered a home in Southwest suburban Tinley Park about 11:30 Tuesday morning, searching for two escaped prisoners.
Jose Banks and Ken Conley are believed to have escaped through the window of their cell at the Metropolitan Correctional Center in The Loop Tuesday morning.
They apparently used a rope to repel about 15 stories down the the south side of the building.
Authorities discovered them missing from their prison cell at the federal jail at about 8:45 a.m Tuesday.
The jail is located at 71 W. Van Buren.
The prisoners were last checked at 5 a.m.
A tan rope could be seen dangling on the outside of the MCC, but police would not say whether it was involved in the escape.
No one was found in the home in the 6600 block of 175th Street, where a relative of Conley’s is believed to live.
But FBI officials said they believe Conley and the other inmate, Joseph “Jose” Banks, were there hours earlier.
Banks, known as the Second-Hand Bandit, was convicted last week of two bank robberies and two attempted holdups. He made off with a combined nearly $600,000 in the heists, authorities said.
Conley is accused of robbing nearly $4,000 from a Homewood bank last year.
Conley was arrested after showing up at a Chicago Heights strip club where he worked dressed in the same black suit and white tie the bank robber wore and flashing a wad of cash, authorities said.
