On Sept. 8, 59-year-old Connecticut resident Barbara Joan March will face a federal judge downtown for mailing candy and baked goods fouled with rodenticide to Supreme Court justices and FBI brass. The feds knew something was up in April when they encountered envelopes leaking brown fluid, but they couldn’t ID the sender because, the FBI alleges, March had given the names of her ’60s-era sorority sisters at Florida’s Stetson University for the return addresses. After one sister told an agent she’d received threatening letters from March years ago, getting her was just a matter of checking her rap sheet: In 1985, she was jailed for shooting at family members on the very same day she reportedly mailed poisoned wine to her mother, father, and brother. Until her arrest in July, March led a relatively low-key existence as french-fry dipper at the Duchess of Black Rock restaurant in Fairfield, Conn. “The only thing different [about her] was she ate food from the garbage,” says restaurant manager Albert Jeudi. “For me, it was a little nasty.”
