Gainesville police reported Monday that dental records were used to positively identify the remains as Christian Aguilar. A statement from police said Aguilar's family has been notified of the identification.
Further testing still needs to be conducted to determine the manner of death.
Aguilar was last seen in Gainesville with his friend, 18-year-old Pedro Bravo, who has been charged with first-degree murder.
Police say Bravo told them he beat Aguilar unconscious and left him in a parking lot. Both Bravo and Aguilar are from Miami.
