The boy and woman said nothing went on between them when first asked. The teen later said the sex act had happened, police said.
The woman hasn’t been charged.
Asked why, Maj. Stephen Fore of DeKalb police said the investigation is ongoing and charges could come after an interview with the teen.
Evans was released Sunday on $2,000 bond.
