(CBS/AP) GAINESVILLE, Fla. - A student under arrest in the case of a missing fellow University of Florida student bought a shovel and duct tape just days before the victim disappeared, police said Wednesday.

Christian Aguilar, 18, was last seen Thursday at a Best Buy store in Gainesville, police said. He was with Pedro Bravo, also 18, who faces a third-degree felony charge of depriving a victim of medical treatment. Bravo was arrested Monday and was being held on $100,000 bond.

Bravo purchased the duct tape and shovel "several days" before Aguilar went missing, Gainesville police said during a briefing Wednesday. Police also said Bravo gave conflicting stories about a fight the two had and was no longer speaking to investigators.

"It is his right, but we believe he is the only person who knows the whereabouts of Christian," said Gainesville Police spokesman Ben Tobias. "It's frustrating because he knows where he is."

Police planned to continue their search for the missing student "until we run out of fresh information."

"With every day that goes forward, the odds and likelihood are less and less" of finding Aguilar, said Tobias.

Bravo and Aguilar attended the same high school in South Florida before moving to Gainesville, about five hours north of Miami. Police also said Bravo may have picked up a hitchhiker sometime Thursday.
