Oliver said the young men thought they had stumbled onto the remains of a dead deer, and maybe they could get a set of antlers. What they found was a decomposed, partially buried body.

"It was obviously human," Oliver said, adding that it was near the dirt road.

The men called the Levy County Sheriff's Office, and Oliver said he got the call about the discovery at 2:30 p.m., with the Gainesville Police Department notified shortly thereafter.

In addition to the Levy County Sheriff's Office, GPD detectives, forensics, Florida Fish and Wildlife and the 8th District Medical Examiners Office responded to the scene. A caravan of more than seven vehicles could be seen departing on the dirt road at around 8 p.m.

The case, which attracted national media attention, went from a disappearance to a fight and abandonment to a murder investigation.

Pedro Bravo's first appearance Aguilar's high school classmate, Pedro Bravo, 18, was indicted for first-degree murder on Tuesday. Bravo has told police he beat up Aguilar in a dispute over a girl and left him by a field near UF's campus.

Aguilar was last seen with Bravo in a Best Buy store on Sept. 20, police said. He was seen in a photo leaving the store wearing blue shoes and jeans.

Crews of volunteers and law enforcement from all over Florida have pitched in to search for Aguilar, but police recently stopped taking volunteers in the search because the mission had switched from a rescue to a recovery.

On Thursday night, concurrent candlelight vigils were held in Miami and Gainesville. Aguilar's body had not yet been recovered, and friends and family still clung to hope.

When asked about the incident late Friday night, GPD spokesman Officer Ben Tobias said he knew it was going to be a bittersweet time for friends and family of Aguilar.

"While some people still hoped to find Christian alive, the unfortunate reality is going to sink in," Tobias said. "I'm glad the family is finally going to get some closure."
