A convicted bank robber who escaped from police custody in 2009 was found guilty Wednesday.

Prosecutors say Robert Maday, 42, was being driven to a courthouse appearance when he freed himself from restraints, grabbed a gun from an investigator for the Cook County state’s attorney’s office and fled.

His escape triggered a 27-hour manhunt in Chicago’s northwest suburbs. During that time, he stole cars from two women at gunpoint and robbed the same bank he had about a year earlier before he was captured f0llowing a high-speed chase.

Regardless of the verdict, Maday already faced a sentence of at least 40 years in prison because of plea deals he already made.
