Which American criminal known for bank robbery was a former police officer?

Jeffrey E. Erickson (c. 1959–1992) and Jill Erickson (c. 1965–1991) were an American criminal couple known for bank robbery.

Jeffrey found work as a truck driver and chauffeur, while Jill, who worked as a lab technician, was a chemistry student at Loyola University Chicago, where she was working toward her degree. The couple never settled down, moving once a year due to complaints from landlords about the dogs and birds they kept. In 1986, Jeffrey became a police officer in Hoffman Estates. He was eventually let go, with police chief Donald Cundiff stating that Jeffrey "lacked common sense". His mother stated that Jeffrey disliked arresting people, as he felt he would be ruining someone's day.

On January 9, 1990, Jeffrey robbed his first bank, the First Nationwide Bank branch in Wilmette. His modus operandi— brazenly entering the bank wearing a fake dark beard, baseball cap, sunglasses, and driving gloves, while carrying a police scanner and announcing a hold-up—would be repeated with the same military precision in most of the pair's subsequent robberies over the next two years. The disguise would later prompt bank employees to refer to Jeffrey as the "bearded bank robber". He wore clothing in layers in order to disguise his weight. Jill's role is believed to have been setting up the getaway cars.
