Maine officials are rolling out a new program to bolster protections against the financial exploitation of the elderly. Through the Senior$afe program announced Monday, staff at credit unions and banks will be trained to recognize red flags of possible exploitation and taught how to report it. Education materials will also be available at banks for community members to learn about financial exploitation. The program is one of several initiatives recently launched to assist the elderly in Maine. Maine has the nation’s highest percentage of baby boomers, at more than 29 percent, and the oldest median age, 43.
