On Thursday, the body of teenager Kayla Campbell was pulled from a North Carolina pond, near the area where her car cell phone, bicycle and helmet were found earlier this week.
"They found her in a pond they were draining. She was found deceased," Faye Fink, a spokeswoman for the Mint Hill Police Department, told The Huffington Post.
Authorities found the 16-year-old's body in a pond east of Interstate 485 in Mint Hill, a suburb about 20 miles southeast of Charlotte. The discovery was made at about 12:15 a.m., roughly 11 hours after officials began draining the pond.
Campbell was last seen leaving her home, which is in the 9000 block of Dartmoor Place about a quarter-mile from the pond, at about 2:30 p.m. Sunday. The teenager was supposed to be home by 5:15 p.m. but when she failed to return Campbell's parents reported her missing at 6 p.m. Sunday, police said.
Police and firefighters in North Carolina began searching the pond for Campbell Monday morning. Although her cell phone, bike and helmet were found nearby, Fink would not say what prompted the search or give any further details.
Campbell's cause and manner of death are still under investigation, police said.
The teen's brother Josh Campbell told WBTV that his sister had been battling depression but seemed to be improving.
"Kayla was getting better," he said. "She was working with professionals who were getting her the help she needs and she was getting better."
A Tumblr blog attributed to Kayla Campbell contains references to suicide and death. It remains unclear Thursday if there is any connection between the posted content and her death.
The FBI on Wednesday searched Campbell's home, but agents have not commented on what, if anything, they found.
Fink would not comment on any other details of the investigation.
The missing teen's mother, Stephanie Campbell, did not respond to a request for comment from HuffPost. Anyone with information on Campbell's death is asked to call Mint Hill police at 704-847-5555.
