FORT MYERS, FLA — Four years and 1000 hours of police work later and there's still been no major arrests in connection to the deadly Club Blu shooting.
Fort Myers police, the FBI, State attorney and Lee County Sheriff's office recently announced that they are teaming up and changing tactics to try and crack the case.
But Trish Routte of SWFL Crime Stoppers says they say they need your help.
"You can't have a mass shooting like that without people seeing something," she said.
They're asking for tips that will lead to an arrest.
"There are people that saw the people that drove up and the people that fired into that crowd," Routte said.
But how helpful are memories from four years ago?
"If you were at Club Blu that night, you are going to have it etched in your brain, what you saw, what you heard, the conversations that happened afterwards. Something like that was so big and massive that you're not going to forget the big things," she said.
In fact, Routte says time, in a case like this, can actually be a good thing.
It gives people a chance to process their trauma and can cool down the fear of retaliation.
"Maybe people's relationship with the people that were involved in this has changed. Twenty thousand dollars, that's life changing money for a lot of people," she said.
She says that right now, there are several cold cases being worked again in Southwest Florida, because someone came forward with a tip years later.
In a case like Club Blu, if you have information that can help, Routte is encouraging you to think of the victims, their families and yourself.
The person or persons responsible for the chaos that night at Club Blu, they're still out there, they're still in our community. And if you can cause that level of chaos and violence and still be here, that's a problem," she said.
To help make coming forward a little easier, there's also a $20,000 reward for tips that lead to an arrest.
