Atlanta ( CNN ) -- Police have found the body of a 7-year-old Georgia girl who went missing more than two days ago , the state 's chief law enforcement official said Monday . Police believe Jorelys Rivera was abducted , sexually assaulted and murdered at her apartment complex in Canton , about 40 miles north of Atlanta , said Georgia Bureau of Investigation ( GBI ) Director Vernon Keenan . `` This is going to be a very , very horrendous crime . I am convinced of that after having observed the body . A child death is always a terrible thing , but a child who dies under extreme violence is the absolute worst thing , '' he told reporters . An autopsy will be done to determine the cause of death , Keenan said . The girl was last seen Friday near a playground at her apartment . Police initially thought she might have wandered off , but after more than 48 hours of searching , they said they believed the girl was kidnapped . Canton police , assisted by the FBI and the GBI , expanded the search area Monday and began canvassing for sex offenders living nearby . They are now asking for help to find out who killed the little girl . Her body was found in a dumpster at the apartment complex where she lived . `` We need help from the public , '' said Police Chief Jeff Lance . As of Monday afternoon , Keenan said , investigators were actively pursuing leads , but police had no one in custody and no suspects . `` Quite frankly , at this point we do not have a strong suspect . We 've not focused in on anyone . We very much need information from the public who may know something about the abduction of this child , '' said Keenan . State troopers were stopping and talking to everyone entering , leaving or driving by the apartment complex Monday afternoon . Earlier , as volunteers and police handed out fliers with information and a picture of the missing child , her mother spent the morning in court trying to regain custody of her other children , who were taken by the Department of Family and Children 's Services for alleged lack of supervision . The girl 's parents are not suspects , Keenan said . Joselin Rivera had spoken with local media hours after her young daughter went missing Friday , saying she just wanted her returned safely . After the girl 's body was found , neighbors said they feared for their safety . Speaking in Spanish , Luis Fernando Montenegro said he was concerned for his daughter , who attends night school . `` If she ( Rivera ) was abducted here and her body was also found here in the ( apartment ) complex , how do we know the killer is not still here ? '' he asked . CNN 's Holly Firfer and Gustavo Valdes contributed to this report .
NEW : ` ` How do we know the killer is not still here , '' a reporter asks . GBI Director John Keenan calls the crime ` ` horrendous '' Officials find the girl 's body in a trash bin after clearing the search area . The FBI joined local police in the expanded search for the missing 7-year - old on Monday .
