SATSUMA , Florida ( CNN ) -- The father of a missing 5-year-old Florida girl made a renewed plea Thursday for the return of his daughter . The search continued Thursday for Haleigh Cummings , 5 , who went missing from her home near Orlando . `` If you have my daughter and you 're watching this , drop her off somewhere safe , '' Roland Cummings said of his daughter Haleigh . `` I 'm not out for revenge , I 'm not out for nothing else . I want my daughter back , '' Cummings said , with his girlfriend , Misty Croslin , at his side . He said he could think of no reason Haleigh would be taken . `` Why would anybody be sick enough '' to abduct a child ? he asked . Cummings , 25 , said earlier that he and Croslin had passed lie detector tests . Croslin , 17 , was the last person to see Haleigh when she put the girl to bed Monday night in their Satsuma , Florida , home . She said she awoke in the middle of the night to find Haleigh gone and the back door to the double-wide trailer propped open with a brick . Putnam County authorities on Thursday continued working with the FBI and state investigators to search a five-mile area for Haleigh . Police have no official suspects , but say they are treating everyone they interview as one . `` All the world 's a suspect '' now , a sheriff 's spokesman has said . Cummings said earlier that he was surprised when he arrived home from work at 3 a.m. Tuesday to see his girlfriend awake , and he asked her why she was up . `` She said , 'Your back door 's open and your daughter 's gone , ' `` Cummings told Nancy Grace on her show on CNN 's sister network HLN on Wednesday night .

The father said he has used the back door only two times since he 's been living in the trailer . Police say they believe the girl was abducted . `` There 's no longer any reason to believe that the child simply wandered outside , '' Maj. Gary Bowling of the Putnam County Sheriff 's Office said Wednesday . The police must `` assume abduction , '' he said , adding , `` All the answers to why you 'd want to take a 5-year-old are ugly . '' Haleigh 's mother , Crystal Sheffield , shook as she spoke Thursday near the search area . Sheffield 's mother , Marie Griffis , said that she and her daughter are devastated . `` It 's like I 've got a hole in my body , and she feels helpless because she ca n't do anything but sit here . '' A nationwide Amber Alert says the girl was last seen wearing a pink shirt and underwear . Croslin is staying with relatives as the investigation continues , said Bowling , describing the girlfriend as a `` child herself . '' Griffis said that her daughter and Ronald Cummings had a `` rocky relationship '' and that the two took turns spending weekends with their daughter . Watch mother 's tearful plea » . It 's unclear if Sheffield and Cummings were ever married , but they are `` legally separated , '' police said Thursday . Authorities were unable to answer media questions about how and why Cummings had custody of Haleigh . Sheffield lives near the Florida-Georgia line and has been interviewed by law enforcement , according to police . Investigators are looking into various angles of the case , including finding out the location of 44 registered sexual offenders who live within a five-mile radius of the Cummings home , said Lt. Johnny Greenwood of the Putnam County Sheriff 's Office . Police are offering but not requiring all those interviewed in the case to take polygraph tests . A familiar face from the Caylee Anthony case is involved in the search . Bounty hunter Leonard Padilla joined the hunt Tuesday and is offering a $ 25,000 reward for the girl 's return . Padilla initially bonded out Caylee 's mother , Casey , who has been charged with first-degree murder in the toddler 's death , and then helped launch one of several searches for Caylee .
