(CBS/AP) Michael Francis Mara, the man dubbed the "Granddad Bandit," has pleaded guilty to robbing two Virginia banks and acknowledged 24 other holdups in 15 states.
Fifty-three-year-old Michael Francis Mara entered the plea Thursday in a federal courthouse in Richmond.
As part of the plea agreement, 18 other federal jurisdictions have relinquished jurisdiction for 24 other robberies committed between 2008 to 2010 in 14 states outside of Virginia, reports CBS affiliate WTVR.
Officials say Mara took more than $83,000 in heists that began in 2008 in Richmond, and ended just before his Aug. 11 arrest after a standoff with police at his Baton Rouge, La., home.
The FBI dubbed the balding and graying Mara the "Granddad Bandit" to help law enforcement and the public easily identify the suspect, whose picture was posted on billboards around the country.
The defense and government jointly recommended in the plea agreement a prison sentence of 300 months. He will be formally sentenced on May 11, 2011, by United States District Judge James R. Spencer.
