This is from the lead investigator on the Pata case...
"There are a few things Dominguez does know, however. The shooting is not believed to be gang-related, nor is it believed to be retaliation for something Bryan did to someone else. Dominguez says the weapons found in Pata's apartment are not believed to be a sign that Pata was hanging in bad circles, and he has no reason to believe Pata's killing was tied to the non-fatal shooting of Willie Cooper, Pata's UM teammate, just four months prior.
Dominguez also confirmed that Pata's shooting is not thought to be related to the FIU-UM on-field brawl, which took place just 24 days before Pata was killed. Dominguez wouldn't comment on whether he believes that Pata's killer was someone Pata knew, but for Pata's family, that seems like a virtual certainty."
The family seems really open to the idea that Bryan Pata knew his killer or that the killer was on UMs football team. They even went so far to say it might have been a setup and the people around him leading up to his death were acting fishy. Personally I wouldn't put much into what the family says unless there is evidence behind it but there doesn't seem to be much evidence at all. It sounds like at this point there just hoping someone comes forward and unless that happens then it will remain a cold case.
