The last in a series of public sessions on financial abuse of seniors will be held in Presque Isle. The workshop is scheduled for Wednesday. Earlier public meetings, also sponsored by a coalition of state government and non-profit agencies, were held in Hallowell, Scarborough, Lewiston and Bangor. The sessions are being held as financial exploitation of elders escalates in numbers in Maine and throughout the country. Maine’s Office of Securities says the sessions are open to the public, including seniors, caregivers and service providers.
