The questions continue to linger and the case of a missing Florida toddler grows colder more than eight months after Melinda Duckett was catapulted into the national eye.

Duckett’s story was first heard last August when she, a grieving 21-year-old student, asked for the public’s help in finding her 2-year-old son Trenton who was allegedly abducted from her Leesburg, Fla., apartment.

Local and national media outlets swarmed Duckett, whom police later labeled as the main suspect. And during a taped interview, CNN Headline News host Nancy Grace interrogated the fragile woman about where she had taken her son before he went missing.

Duckett had told police she was watching a movie with friends in the next room where Trenton was sleeping. She discovered that her son was missing a few hours after she put him down to sleep. It was suspected that Trenton was taken through the bedroom window, of which the screen was slashed.

Less than two weeks after a search was launched for her toddler in the Ocala National Forest and shortly before her interview with Grace aired, Duckett killed herself with a shotgun in her grandparents’ bedroom closet.

“Nothing really new or earth-shattering has happened [since then],” said Leesburg Police Department Capt. Steve Rockefeller of the case in late March. “It’s still an open investigation and Melinda is our only suspect in the case. … We don’t have any physical evidence one way or the other. We have to face the possibility that [Trenton] is dead.”

Rockefeller said there have been many theories behind Trenton’s disappearance, including one that could lead police to South Korea — Duckett’s birthplace. Duckett had told a co-worker that she wanted to expose her son to the Korean culture.

Police pored through records of passengers who went to South Korea from the U.S. the day Trenton disappeared, but found nothing. The police department is continuing to work with other agencies, including the Marion County Sheriff’s Office and the Federal Bureau of Investigation, on the case.

“Our primary focus is to bring him home,” Rockefeller said.

In an apparent suicide letter addressed to the public, Duckett described how she was misunderstood and “sinking after [the] one week mark of Trent being gone.”

In addition, she wrote: “Your focus came off of my son. I love him and only wanted him safe in my arms. You created rumors and twisted words. Usually I am strong and what others say does not affect me. However I am young, have worked my ass off and [am] still being faced with ridicule and criticism.”

Duckett had written three letters, including one to her grandparents and parents.

After Duckett’s death, relatives filed a wrongful-death suit against Nancy Grace and CNN, claiming that Melinda’s suicide was spurred by stress after the interview with Grace.

“Everything is at a standstill,” said Kara Skorupa, an attorney representing Duckett’s adoptive parents and Duckett’s estate. “Regardless of what happens in the courtroom, we just want the baby found.”
