( CNN ) -- A girl who was shown on a videotape being sexually assaulted in Las Vegas has been found and is safe , officials in Nye County , Nevada , said Friday . Chester Arthur Stiles , 37 , is being sought as a suspect , police say . `` We have found the child , Madison . She 's safe . The detectives say she is in good condition , '' Nye County Sheriff Tony De Meo said . The girl , now 7 , was shown in a sex video made four years ago , Detective David Boruchowitz said at a news conference Friday night . She was found Friday with family in Las Vegas after thousands of tips poured in , thanks to an appeal by police to the news media to show the girl 's picture . CNN and other news organizations did so until the child was found , when De Meo asked them to stop showing the picture . `` The mother has cooperated with us , '' De Meo said . `` We believe that the mother was not aware of anything that went on with this young girl , '' he said . `` It was very sad for her to find this out . '' A former Las Vegas animal trainer , Chester Arthur Stiles , 37 , a resident of Pahrump , Nevada , has been identified as a suspect and is being sought in the case , De Meo said . Pahrump is about 60 miles west of Las Vegas . Watch what 's known about Stiles » . Stiles was a distant friend of the girl 's family , De Meo said . Someone close to Stiles has told investigators that Stiles is a `` survivalist type '' and always carries a weapon , Nye County District Attorney Bob Beckett said . De Meo addressed Stiles directly : `` Turn yourself in to your local law enforcement agency , '' he said . `` Understand this : Law enforcement not only has a long arm , but a long memory . You will not be forgotten by members of this agency or any other law enforcement agency . '' The FBI is also seeking Stiles on state charges of sexual assault and lewdness with a minor under the age of 14 in a separate matter , De Meo said . Police , who had called Stiles a person of interest , began calling him a suspect late Friday . There appeared to be physical similarities between Stiles and the man in the videotape , De Meo said . `` Nothing that I have seen in my career comes close to what this girl has gone through . Whoever this person is is a predator that , as far as I 'm concerned , belongs in custody and , if successfully prosecuted , in jail for as long as the law allows , '' De Meo said earlier . Detectives said the child showed little emotion during the rapes , indicating she may have been brutalized before . Nevadan Darren Tuck recently gave police the videotape , saying he found it in the desert , De Meo said . Police said the tape was in his possession at least since May before he handed it over to authorities . He is being sought on a parole violation for failure to pay child support , but police -- who want to question him further -- have been unable to locate him . Tuck , who also allegedly showed the tape to others before giving it to police , faces a possible 10-years-to-life sentence for exhibiting pornography and another one to six years for possession of child pornography , De Meo said . Harry Kuehn , Tuck 's attorney , said this week on CNN 's `` Nancy Grace '' that Tuck was `` racked by indecision '' about what to do with the tape once he realized what it was . Asked why , Kuehn said , `` He 's explained that to us , and at this point , we 're not going to share that , because it goes to the defense of the matter . '' `` You have to consider what kind of concerns my client had ; He 's previously dealt with the sheriff 's office in Nye County ; it was previously unsatisfactory , '' the attorney said .
