FORT MYERS, Fla. - It's been nearly 5 years since a Fort Myers man was murdered. His mother has not only struggled with the loss of her son, but also with the knowledge that the person who did it is still out there.

Open a new deck of Crimestoppers playing cards, and the first face you'll see is 31 year-old Josh Kent.

"That shooter's out there and he's still alive," Kent's mother Debbie Harrison said. "Even if he goes to jail, he'll still be alive. My son's not. It's not fair."

May 7, 2006, Fort Myers Police found Kent near Royal Palm and Katherine Streets, shot and killed behind the wheel of his car. Kent was a husband and a father. Detective Albert Antonini said it's been a tough case to crack, with no fingerprints or foreign DNA found on scene, and few witnesses willing to speak up.

"Even if it's just a tidbit of information they didn't think was important at the time, now or anytime in the near future, that that piece of information comes out, it could be the piece that solves the case," Antonini said.

5 years later, Debbie Harrison struggles with depression, anxiety, and the fact that someone is living with a guilty conscience while her son is gone forever. "I don't know how these people live with themselves," Harrison said. "I don't know how they cant look in the mirror and see the face of that person they killed every time they look in the mirror. Do these people know what it's like to have to go to a graveyard?"

For now, Harrison calls and writes to detectives and TV hosts like Nancy Grace and John Walsh. She's even sought guidance from a psychic. This mother wants justice, and said until she draws her last breath, she'll keep fighting for it.

About a year ago, local and state law enforcement began holding cross-agency meetings where one agency presents an unsolved homicide case, and the others offer ideas and information on new technology that could potentially solve it.

If you know anything about the murder of Josh Kent, there are several ways to tell police anonymously.
