Dina Manfredini, a 115-year-old Iowa woman who was named the world's oldest person less than two weeks ago by Guinness World Records, died Monday, her granddaughter said. Lori Logli told Reuters that Manfredini, who was born in Pievepelago, Italy, died at a retirement home in Johnston, Iowa, where she lived. Guinness said the world's oldest living person now is Japanese man Jiroemon Kimura, who is also 115 years old.
