Aguilar's friends and family planned to gather Friday at the cemetery where he's buried on what would have been his 19th birthday, according to the station.

Thursday, a grand jury indictment revealed that the slain freshman was sedated with a chemical compound and then suffocated before his body was dumped in the woods. The document did not specify the type of chemical compound.

Aguilar was last seen on Sept. 20 in Gainesville with his friend, 18-year-old Pedro Bravo, who has pleaded not guilty to first-degree murder in the killing. Bravo also reportedly faces charges of kidnapping, poisoning and tampering with evidence

Aguilar's father, Carlos, thought his son had been beaten and left for dead, possibly fighting to survive as his family and volunteers searched through the woods of Alachua County for days.

He was relieved to hear his son appeared not to have died painfully, CBS Miami reports.

"This is his way to say, 'This is my present. I did not suffer that much'," Aguilar said of his slain son.
