DES MOINES, Iowa (AP) -

The family of world's oldest person Dina Manfredini says the woman from Johnston, Iowa, has died at age 115.

Manfredini's granddaughter Lori Logli says she died early Monday. She had lived at a care center in Johnston, just north of Des Moines.

Guinness World Records had confirmed Manfredini inherited the title of world's oldest living person less than two weeks ago.

Guinness spokesman Robert Young says a Japanese man, Jiroemon Kimura, now holds the title. He is just 15 days younger than Manfredini.
