Miami Beach police said Friday that a human head that washed ashore on Key Biscayne on earlier this week belonged to a 19-year-old swimmer who disappeared off South Beach over the weekend.

Victor Castaneda got caught in a rip tide and was reported missing at about 6 p.m. on Saturday, WSVN reported, prompting an extensive search that turned up no sign of the young man.

The head was found on a Key Biscayne beach Tuesday morning by someone raking the sand, as CrimeOnline reported, and the Miami-Dade Medical Examiner confirmed the identity on Friday.

“The Miami Beach Police Department extends prayers and condolences to the family,” police said in a statement. “Our victim advocates will continue to provide support to the family during this time.”

Police are still investigating Castaneda’s death.
