World's Oldest Person Dies at 115

The world's oldest known person has died in Los Angeles at age 115.

Dr. Charles Witt says Gertrude Baines died Friday at a hospital. The doctor says she likely suffered a heart attack but an autopsy will be conducted to confirm the cause of death.

Baines was born in 1894 in Shellman, Georgia. She became the world's oldest living person when a 115-year-old woman, Maria de Jesus, died in Portugal in January.

Baines received a letter from the president when she celebrated her 115th birthday April 6.

The oldest person in the world is now 114-year-old Kama Chinen, who lives in Japan. That's according to Dr. L. Stephen Coles of the Gerontology Research Group at the University of California Los Angeles Medical Center. The group tracks claims of extreme old age.
