Two Connecticut women face sentencing for running a pyramid scheme that authorities said involved millions of dollars and more than 1,000 other women. Guilford residents Donna Bello and Jill Platt were scheduled to be sentenced Tuesday in US District Court in Hartford. A jury convicted them in February of fraud, conspiracy, and tax crimes. Their lawyers say they should receive lenient sentences because they believed they were not breaking the law. Authorities said the scheme involved women joining ‘‘gifting table’’ clubs for $5,000, then receiving $40,000 by recruiting eight new members who paid $5,000 apiece. Authorities said victims of the scheme lost more than $2 million.
