"If you had an 18- and 17-year-old, there may be some investigation," he said.
"If the 17-year-old says it was consensual, that would probably be the end of it and you wouldn't have charges."
But in this case, 18 and 14 is a wide gap, he said. "According to law in Florida, this is a crime."
It doesn't matter -- and shouldn't matter -- what people in an online community who don't have the investigative details of a case believe, he said.
He drew a comparison to the Jodi Arias case currently under way in Arizona. Many people -- even those on the jury -- said they couldn't conceive how a petite woman who claimed she'd been the victim of domestic violence could repeatedly stab her boyfriend, as she admits doing.
"As a prosecutor you cannot be influenced by anything other than the facts," he said.
While some have suggested this case is being handled differently because it involves two females, Indian River County Sheriff Deryl Loar said that has nothing to do with it.
"If this was an 18-year-old male and that was a 14-year-old girl, it would have been prosecuted the same way," he said.
Parents of girl, 14, say they are protecting her
At trial, the prosecutor is likely to try to put on witnesses who can show that the 14-year-old was damaged psychologically by engaging in sex at such a young age, and that she wouldn't have normally done such a thing.
In an earlier interview with CNN affiliate WPEC, Jim and Laurie Smith insisted that the girls' gender has nothing to do with the case. They are concerned about ages.
"Our daughter was 14, and this girl was 18," said Jim Smith.
According to the Smiths, they twice warned Hunt to stop.
"I had another adult, who is a mother, she came to me and said, 'Ms. Smith, you need to know this.' She said, 'We told Ms. Hunt to leave your daughter alone but they are in a relationship. And, she's 18.'"
Laurie Smith said she was shocked. Her daughter was just too young, she thought.
The 14-year-old began to act out, the Smiths told WPEC.
Then one weekend morning the Smiths went to their daughter's bedroom and discovered she was missing.
They panicked, thinking someone took their daughter or that she was hurt. "Her running away was the furthest thing from our mind," said Jim Smith. "We thought ... you hear about kids getting abducted from their homes."
But they later learned that Hunt had picked their daughter up, they told WPEC.
"We had no other alternative but to turn to the law, use it basically as a last resort," Jim Smith said.
Bloggers have called Laurie Smith a gay basher and accused her of being abusive to her daughter. Numerous news reports have asked whether the Smiths went after the teen because of her sexual orientation.
But Smith says her goal is to protect her 14-year-old, and she will not relent.
"I will be an advocate of what she needs," the mother told WPEC. "The stories that people are saying ... I love my daughter. ... I'm willing to do whatever to protect her."
"This whole story about you blaming Kate for making your daughter gay ... where did that come from?" a reporter asked the parents.
"I don't know. It didn't come from us. That's not how we feel," Jim Smith answered.
