There have been five “CSI” shows with actors playing forensics experts — “CSI: Crime Scene Investigation,” “CSI: Miami,” “CSI: New York,” “CSI: Cyber” and “CSI: Vegas.” Now it’s time for the real experts to bask in the spotlight.

“The Real CSI: Miami,” which premiered recently on CBS, is a documentary- style look at the hunt for real criminals told by the officers and lab-coated pros who actually solved the murders.

“ ‘CSI’ has that ability to live in different spectrums,” says writer-producer Anthony E. Zuiker, who created the hit franchise. “It made perfect sense to try the unscripted version of the show because the format could still relatively be the same.”

The series uses real 911 calls, actor portrayals, surveillance video, interrogation and body camera footage, crime scene images, cool graphics and re-creations. There are also interviews with survivors and family members to underline the pain of loss.

“I know what makes ‘CSI’ work and what does not work. And what does not work is when the episodes are emotionally vacant,” says Zuiker. “It’s very important to have the survivors and emotionality. That was one of my No. 1 mandates to have.”

The technicians and officers explain their thinking on motives and clues and return to key crime scenes. So if a detective went scuba diving for a vital clue, we see him back in the water describing how he found it.

“You have to make sure it still feels like a ‘CSI,’ but you also don’t have the ability to get extra creative in the writing because you have to stick to the bona fide facts of the case,” says Zuiker. “That was the challenge.”

One of the first episodes revisits the 2015 gunshot murders of couple Tara Rosado and Carlos Ortiz in the Florida Keys. Their bodies were found in a bedroom, with signs of a struggle but no gun was recovered. “That tells me there was someone else in the room. And that’s when the hunt for the killer began,” says investigator Mary’s Martinez.

Viewers watch as authorities eye an ex- husband before the discovery of an old gun in a canal leads scuba teams to find a submerged iPhone nearby that reveals the reason for the murders might have been a fight between friends over a bale of cocaine.

“A lot of what I had to do with the producers of the show was to give them the confidence that the forensics was not boring and that the forensics drove the narrative,” Zuiker says.

In many ways, “The Real CSI: Miami” is a nod to the forensic sciences that sparked the birth of “CSI.” Zuiker was inspired after watching an episode of “New Detectives” on the Discovery Channel about a cheerleader killed by an obsessed photographer.

Detectives in that case found the dead woman’s hair follicles in the suspect’s car, determined the body had been redressed and that she was wearing no makeup, undermining the killer’s alibi that she was doing a photoshoot.

“I think when those three particular pieces of evidence were explained to me as a novice in forensics, I realized that the body was a perfect specimen to solve crime,” Zuiker says. “That’s how ‘CSI’ was born.”

Zuiker was 28 when he realized he had a potential show on his hands. Now he is 55 with a hit, Emmy-winning franchise that rivals the “Law & Order” universe. “Did I think we’d get past 13 episodes? No. Did I believe we had something special? Yes,” he says.

“CSI” has indeed proved a durable property, going from the desert of Las Vegas to the waters of Miami and into the urban jungle of New York and even online.

“This is a particular franchise that can live and be malleable in scripted, unscripted and docuseries, movie formats, gaming formats,” he says. “I think, for me, personally, this ‘Real CSI: Miami’ is a tremendous pivot in the right direction to keep the entire franchise healthy.”
