ROSWELL, Ga. — The Fulton County Medical Examiner’s office has confirmed that the body found near a Roswell swimming pool on May 29 is that of a missing Johns Creek teenager.

That morning, the Johns Creek Police Department started an investigation after 17-year-old Centennial High School student Mercedes Chico-Sims was declared missing. 

A few hours later, shortly after 10 a.m., maintenance personnel at Atlantic Newtown Apartments on Nesbit Ferry Road called 911 after finding a body. 

Roswell police investigated the incident and ruled it was a suspicious death. 

Two days later, the deceased person was confirmed to be the missing teenager.

The family of Chico-Sims said in a statement that they were devastated to learn about her fate and are asking for privacy during the grieving process.

“Beyond our grief, our commitment is to honor and remember the life of Mercedes with the support of our family and friends,” the statement said. “We are cooperating with both the Johns Creek and Roswell police departments in their ongoing investigations. If anyone has any information that will help in the investigation into Mercedes’ death, please notify the police immediately.”

A Roswell resident, 18-year-old Elijah Foster, has been arrested and charged with concealing the death of another in connection to the incident. 

Foster was also charged with statutory rape for what police said is an unrelated case. 

The investigation is still ongoing and new developments will be reported as they occur, said Roswell Police Lt. Noah Caplan.
