At 80 years old, he married a woman 17 years his junior, who, over their three-year union, according to the family, cashed $40,000 in blank checks sent by his credit-card issuer and emptied the contents of his $123,000 annuity, leaving him with little more than a giant tax bill.Mr. Taylor, a former diesel mechanic and Korean War veteran, gave his wife permission to make two annuity withdrawals over the phone. But his wife, who couldn’t be reached for comment, made 20 more withdrawals on her own by using her husband’s Social Security number and other identifying information, and signing papers to direct money into a joint account, according to documents provided by Ms. Clark.
