Atlanta ( CNN ) -- A 7-year-old girl whose body was found in a trash bin outside her Georgia apartment building died of blunt force trauma to the head , was stabbed and had been sexually assaulted , authorities said Tuesday . The killer probably lives in the apartment complex where the child lived or had ready access to it , said Vernon Keenan , director of the Georgia Bureau of Investigation . `` We have multiple leads we feel are valuable and we 're going to carry those out , '' he said . Sixty-five state and federal investigators are trying to piece together the events that led to the killing of Jorelys Rivera at an apartment complex in Canton , about 40 miles north of Atlanta , where the girl was found three days after she went missing . Jorelys likely died between an hour and an hour and a half after she disappeared , Keenan said . Keenan also said that investigators uncovered what they believe is blood in a vacant apartment unit . They do not currently have any suspects in custody , he added . Relatives of the little girl mourned her death . `` My world collapsed , '' her father , Ricardo Galarza , told CNN affiliate WAPA in Puerto Rico . `` I could n't believe that they robbed her from me . '' `` They destroyed my soul , '' her grandmother , Wanda Ivette Rivera , told the same network . `` They took a piece of my heart . '' Another family member , Miriam Rivera , urged the state of Georgia to `` throw the full weight of the law to the person who did this . '' Police have asked for help from the public to find out who killed the little girl . She was last seen alive 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 she was kidnapped . `` It 's so close to home . To think she was just right there at the park and from there disappeared is the scariest thing , '' Maria Rodriguez , a friend of the girl 's mother , told CNN . Canton police , assisted by the FBI and the GBI , expanded the search area Monday and began canvassing for sex offenders living nearby . Earlier in the day , 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 over the weekend in the wake of Jorelys ' disappearance for alleged lack of supervision . Her request was denied and the children remain in DFAC 's custody , according to the Cherokee County Sheriff 's Department . 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 . CNN 's Gustavo Valdes contributed to this report .
