Teresa M. Knowles, 39, appeared before U.S. District Judge Frederick J. Kapala and pleaded guilty to two counts of bank robbery and one count of attempted bank robbery.
The guilty plea was announced by Zachary T. Fardon, U.S. attorney for the Northern District of Illinois and Michael J. Anderson, special agent-in-charge of the Chicago Office of the FBI.
According to the written plea agreement, Knowles drove a Nissan SUV to the Crystal Lake Chase Bank, 1185 S. Route 31. She approached a teller window and passed the teller a note that demanded $10,000. The teller first handed Knowles $400, and then another $2,450 when the teller was told that wasn't enough.
Knowles also admitted in the plea agreement to driving on March 24 to a Chase Bank in Grayslake where she handed a teller a similar note and was given $1,000.
Also according to the agreement, she admitted to going to a Johnsburg Chase Bank, at 2911 Commerce Drive. She handed a teller a similar note, was refused, and walked out of the bank.
The Northwest Herald previously reported Knowles was arrested in the 1600 block of Richmond Road in Johnsburg after being stopped by McHenry police.
Each count of bank robbery and attempted bank robbery carries a maximum potential penalty of up to 20 years in prison, up to three years of supervised release after imprisonment, a fine of up to $250,000, and full restitution, federal officials said.
Sentencing for Knowles is set for 2:30 p.m. Feb. 4, 2016.
The Johnsburg Police Department, McHenry Police Department, Grayslake Police Department, and Crystal Lake Police Department assisted in the investigation.
The government is represented by Assistant U.S. Attorney Michael D. Love.
