The Horry County Police sincerely thank everyone who assisted in the search for McKenna. Additional information will be disseminated as it becomes available."
Horry County Police are searching for a South Carolina teen who went missing on Thursday morning, Aug. 20. She missed her first day of school the same day.
Marley McKenna Spindler, who goes by McKenna, was last seen at a Chick-Fil-A restaurant in Surfside Beach, S.C., at approximately 7:30 a.m.
The police investigation has found that the teen left breakfast with friends in her 2002 silver Ford Escape and drove to pick up a drunk male friend on Ocean Blvd. in Myrtle Beach.
She was next seen on surveillance camera in changed clothes withdrawing less than $100 from her account, according to police.

Her male friend was later located by police and cleared of involvement.
A clerk found Spindler's phone in the parking lot of the Ocean Reef Resort later Thursday. When the teen's father called the phone after school, the resort answered.
A search of the phone found evidence that Spindler left the restaurant on her own and not under duress or coercion. Police said there is no evidence of foul play.
"She's 16, she's very young and maybe she didn't intend to get in a bad situation, but may find herself in one now," said Shelley Long, Spindler's aunt.
Spindler is described as a 16-year-old white female with brown hair and hazel eyes, standing 5 feet 8 inches tall and weighing about 100 pounds. She was last seen wearing pearl earrings, blue jeans, a white top, gold sandals and carrying a cross-body purse, according to WMBF.
Her 2002 silver Ford Escape SUV bears South Carolina license plate number KFI776. Spindler's mother said the teen had recently received her driver's license and is not familiar with driving around town.
