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.

This is shocking, shocking. You don’t hear a lot about that. You heard about drugs washing up on shore and things like that, but a head!” Miami resident Marcelo Borrelli said.

The human head that washed ashore in South Florida this week belonged to a missing 19-year-old swimmer, police said Friday.
