Christian Aguilar missing updates: Search for University of Florida student continues to expand

  Police had no new developments Thursday in their investigation into the disappearance of a University of Florida student.

Gainesville police spokesman Ben Tobias told the Gainesville Sun the search area for Christian Aguilar continues to expand, and that there will be a new command post location for the search tomorrow.

An 18-year-old was arrested Monday in the case.

Gainesville police say Pedro A. Bravo faces third-degree felony charges of depriving a victim of a crime of medical treatment. He was arrested Monday afternoon.

Aguilar,18, was last seen Thursday, Sept. 20. Police say the two were fighting over a girl.

Police told the Gainesville Sun that Bravo has given them three versions of what happened. In one version, they just talked. In another, he hit Aguilar and then left. The other version has Bravo beating Aguilar unconscious before leaving him in a parking lot.

Police spokesman Ben Tobias says Bravo has taken investigators to several locations where he says he had been with Aguilar. Nothing was found at those locations.
