( CNN ) -- Police digging for clues in the deaths of six people found in the New Mexico desert hope the identification of one set of bones will generate leads . An Albuquerque , New Mexico , police forensics team member digs last week at the burial site . The remains of Victoria Chavez and five other people were found in a 92-acre area housing development under construction just west of Albuquerque . Chavez was a prostitute and drug user who was last seen in 2003 and reported missing in 2004 , Albuquerque police said . The six bodies were found after a woman walking her dog found a human bone two weeks ago and notified police , said John Walsh , Albuquerque police spokesman . Authorities have not yet identified the other five sets of bones but say they might find others . Attempting to piece together identities could take a long time because , they said , `` it 's very difficult '' to determine cause of death from skeletal remains . `` We 're going off of one remain so far , '' Walsh said . `` And that 's all we 've got at the moment . We 've only got skeletal remains . `` This is a slow go , '' Walsh said . `` Things wo n't pop up in hours , likely in weeks . '' Chavez 's remains were identified through dental records that her family provided when she was reported missing in 2004 . It will be tougher to identify the others . For example , one had no dental work and another had no skull . The cause of Chavez 's death was not known , but Walsh speculated that her death could be related to violent sex trade . He said police are looking at reports of missing prostitutes over the years and are trying to determine possible suspects . He said he hopes family members of those missing could help authorities . Police are trying to figure out how the bodies got there . They are investigating the possibility that one person put the bones there . `` At this stage , the best way I can describe it , we have a handful of theories , '' Walsh said . The names of two dead men have surfaced during the investigation of Chavez 's death , Walsh said , confirming a news report . One was a pimp who died of natural causes . The other was killed by a pimp after he killed a prostitute , the report said . The last set of remains exhumed at the site was nine or 10 feet deep . Authorities were using heavy and light equipment and cadaver dogs to find bodies and clues . Investigators think there could be even more remains buried on the New Mexico site .
NEW . Only one body identified ; she was a prostitute last seen in 2003 . The bones of six bodies found in desert west of Albuquerque . Authorities fear remains of even more bodies might be buried there .
