COLLIER COUNTY, Fla. - Collier County Sheriff's investigators say they've received 240 tips in the case a missing Immokalee boy.

They are still waiting for that one phone call that will help bring 6-year-old Adji Desir home.

They're encouraging anyone with information, no matter how minuscule, to call in.

"Please don't dismiss anything that you may think you know because we would rather go on a hunch than not be able to follow up on it at all," said Trish Routte with Southwest Florida Crime Stoppers.

Adji was last seen on the night of January 10th, playing outside with other kids in the Immokalee Farmworker Village.

Even after a massive week long ground search and a task force effort that continues today, there is still no sign of the little boy.

Routte said, "We're begging people for information at this point. We want the safe return of this little guy."

A new push to find the little boy is coming in the form of fliers.

Crime Stoppers will start releasing new fliers within the next few days with Adji's picture and the updated reward for his safe return, which is now $33,500.

Collier County Sheriff's investigators tell WINK News the fliers will be posted across Southwest Florida and in Haitian communities in Fort Lauderdale and Miami.

It's still not known whether Adji simply walked off or was abducted.

A task force of investigators from the Sheriff's Office, the Florida Department of Law Enforcement, even the FBI is working every day on Adji's case, but they need help.

"We need to know where he is at," said Routte, "We're at a point of desperation."

Anyone with information is asked to call Crime Stoppers at 1-800-780-TIPS.
