KISSIMMEE, Florida (CNN) -- Two sisters were found Sunday in Central Florida, a day after they wandered off from a campground where they were staying with their family, authorities said.
Elizabeth Murrell, 12, and her sister Amanda, 9, had been last seen at 4:30 p.m. EST Saturday at the Tropical Palms Resort, west of Kissimmee, where their parents and four siblings were staying, Osceola County Sheriff's detective Michelle Keefer said.
The family of the missing girls lives in Savannah, Georgia.
The parents called the sheriff's office about 6:45 p.m. when the girls didn't return, Keefer said Sunday.
"They had asked their parents if they could explore the woods," she said. "Of course, then the parents wondered where they were."
Keefer said the Florida Department of Law Enforcement called an "Amber" alert for the girls, activating signs on turnpikes and major highways asking the public for leads.
Amber (America's Missing: Broadcast Emergency Response) is a voluntary partnership between law-enforcement agencies and broadcasters to activate an urgent bulletin in the most serious missing child cases. The system was created in 1996 as a legacy to 9-year-old Amber Hagerman, who was kidnapped while riding her bicycle and murdered in Arlington, Texas.
