MIAMI -- It's been almost four months since the death of University of Miami football player Bryan Pata.

While the leads in the case appear to be dwindling, police said, the controversy between the Pata family and university continues to heat up.

Bryan was slain outside of his Kendall home in early November.

The senior defensive lineman was expected to be drafted this year into the National Football League, so in his honor, his two brothers Edwin and Edrick are asking the university to let them take his place during the school's NFL scouting day.

"The Patas don't want a handout," Arless Carballo said. "They just want to be able to do what Bryan cannot do anymore and that is be in the pro league."

Carballo is a chemistry teacher at Miami Norland Senior High School and is also the agent representing the Pata brothers. He said he has over 20 clients, none in the NFL, but 10 in the arena football league.

"The NFL said they have no problem with it, it is up to the university and the university does not want to allow it," said Carballo.

Edwin played for Florida State University this past season and will get his pro-day with FSU, but Carballo said Edwin still wants to participate with UM.

"It's not a matter of doing it in front of scouts, it is a matter of something he feels he has to do for Bryan, who is no longer here," Carballo said. "It is part of the healing process."

Since Bryan's death, the university has held vigils and donated money to the Pata family and according to published reports, UM will allow the Patas to participate in the portion of the tryout for non-UM players.

But the main tryout is for Hurricanes and Hurricanes only.

NBC 6's Tom Llamas asked Carballo why the University of Miami and its boosters would owe the family of Pata anything more after they have donated tens of thousands to the Pata family as well as to Crime Stoppers to help find Bryan Pata's killer.

"UM actually does not owe them (Pata family) anything," Carballo said. "As I said before, this is a gesture and a request that we put through to the university."

The University of Miami had no comment as of Monday afternoon.

Carballo said that he is set to meet with Bishop Victor curry from the local NAACP chapter and other local civic leaders to see if they can change the university's mind.

So far, there have been no arrests in slaying of Bryan Pata.
