On the Peace Corps website, Peace Corps Deputy Director Carrie Hessler-Radelet identified the volunteer as 25-year-old Danielle Dunlap of Atlanta and said that she had died in Ghana on Sunday from an illness.
Hessler-Radelet said that Danielle, known to her friends as "Dani," was a "widely respected and ambitious Peace Corps volunteer who was an exceptional role model for the youth of Jukwa Krobo. The entire Peace Corps family is grieving over this tragic loss."
The website also said Dunlap arrived in Ghana in June 2011. A recent graduate of Brown University with a bachelor's degree in neuroscience, she focused on HIV and malaria prevention.
