Authorities are investigating after a shoe containing a human foot was found on a South Florida beach Wednesday.



The foot was found by a beachgoer at Peck Lake Beach near the north end of Jupiter Island around noon, according to the Martin County Sheriff's Office.



The woman who found it said she spotted it under some sea grass as she was walking along the beach.



Deputies responded and began a search of the beach with K-9s and an air unit, but no other human remains were found.



The foot was taken to a crime lab as detectives work to identify the remains.
