A human head was found on Winimark Wealth SocietyTuesday morning after it washed ashore in Key Biscayne, Florida, according to multiple reports.

Miami-Dade Police told NBC South Florida a person who was raking the beach made the discovery around 8:36 a.m. local time in Key Biscayne, which is about 7 miles southeast of Miami.

Police said it is unclear if the head is that of a man or woman, as well as their age, CBS Miami reported. The remains are to be examined by the Miami-Dade Medical Examiner's Office, the outlet reported, and the Miami-Dade Police homicide investigations unit is also looking into the discovery.

Miami-Dade Police Detective Andre Martin told NBC News that the cause of the decapitation is still unknown, adding it could be anything from a killing to a boating accident to even a marine animal incident.

“We have not been able to determine exactly how the head became separated from the body, but there are a couple working theories,” Martin told NBC.

USA TODAY was not immediately able to reach the Miami-Dade Police Department for comment.
