Detectives in Florida looking for a missing 5-year-old girl sorted through tons of trash in a dumpster near the family home after cadaver dogs picked up a scent, but turned up no new evidence.

Investigators from the Putnam County Sheriff's Office spent several hours Thursday evening going through the garbage piece by piece in their search for Haleigh Cummings, Capt. Dick Schauland said in a news release.

The dumpster search was prompted by three cadaver dogs that apparently picked up a scent at the receptacle, according to Schauland.

Haleigh vanished from her bedroom about three weeks ago.

Seven teams of canines spent the day Thursday in the area around the mobile home where Haleigh lives with her father Ronald Cummings Jr., his girlfriend Misty Croslin and her 4-year-old brother Junior.

Schauland said the endeavor wasn't the result of any new information in the case but a "routine procedure of re-checking areas that had been previously searched to be sure that nothing had been overlooked."

The dogs were continuing the effort Friday.

The news came as Haleigh's family released a home movie Thursday of the child opening Christmas presents in the hopes that it will lead to tips on where she is.

In the silent 41-second video clip, Haleigh and Junior are sitting on the floor by a Christmas tree this past Dec. 25. The little girl smiles, laughs and talks to the off-camera photographer as she plays with a hat and unwraps gifts. Her light brown hair is pulled back in a ponytail.

The video was released after the reward for Haleigh's return was raised to $25,500. The child vanished before dawn on Feb. 10.

Police are combing through more than a thousand possible leads, but so far have found no trace of Haleigh.

Several of those questioned have taken polygraphs, including Cummings, 24, and Croslin, 17. The couple claimed to have "passed" the lie detector tests. Police won't talk about the results.

The family has been the subject of child welfare agency investigations in the past. The nature of those cases hasn't been disclosed because of state confidentiality laws.

Haleigh's little brother told police a man dressed all in black snuck into her room and snatched the girl from her bed, according to a Florida TV news Web site. Detectives haven't addressed his story.

Anyone with any information is asked to call Crimestoppers at 1-888-277-TIPS (8477).
