( CNN ) -- In an anguished 911 call , a Georgia man told dispatchers that he arrived home to find `` my whole family 's dead . '' Seven people were found dead Saturday at a residence in a mobile home park in Brunswick , Georgia . `` I just got home , '' a man identified as Guy Heinze Jr. told the emergency dispatcher in the Saturday call , released Monday by authorities . `` I was out last night . I got home just now , and everybody 's dead . ... My whole family 's dead . It looks like they 've been beaten to death . '' Seven people were found dead Saturday at a residence at the New Hope mobile home park in Brunswick , Georgia , authorities said . Two others were hospitalized in critical condition ; one of them , identified by police as 19-year-old Michael Toller , died Sunday . The remaining survivor remained in critical condition on Monday , police said . A neighbor of Heinze 's placed the call and put him on the phone , as well as the mobile home park 's maintenance man . The park manager also called 911 , sobbing as she told dispatchers , `` Please hurry . '' Listen as the 911 operator hears a family has died » . Police said Sunday that they have `` no known suspects '' in the case . `` We are not looking for any known suspects , '' Glynn County Police Chief Matt Doering said . `` That does n't say that there are no suspects . They 're just not known to us . '' Heinze was arrested Saturday night and faces charges of possessing a controlled substance and marijuana , as well as evidence tampering and making false statements to a police officer , Doering said . He said Heinze has been cooperative and stopped short of naming him a suspect in the deaths . `` We 're still looking for anybody and everybody that may be related to this , '' he said . `` That naturally includes [ Heinze ] . Of course we 're looking at him . '' `` I do n't know what to do , man , '' an emotional Heinze told the dispatcher . `` My dad , my mom , my uncle , my cousin ... my dad , he 's laying there dead . That was my dad . '' `` It 's a house full of people that live there , '' the neighbor said during the call . `` I know there 's a baby . I do n't know if the baby was in there or not . '' At one point , while the maintenance man , identified only as Mike , talked to dispatchers , Heinze went into the mobile home and reported that his cousin , identified as Michael , was still breathing . Asked to describe Michael , the maintenance man said that Michael is a `` young man with Down 's syndrome . '' Heinze reported that the youth 's `` face is smashed in , '' he said . Heinze got back on the phone to talk to a supervisor , repeating that Michael was breathing , although he appeared to be having trouble breathing and needed an ambulance . The dispatcher assured him that help was on the way and tried to question him gently . `` People 's beat , '' Heinze said . `` Everybody is dead . '' Asked what the mobile home looked like , he yelled , `` It looks like a [ expletive ] murder scene . '' At the dispatcher 's suggestion , Heinze tried to question Michael , asking him , `` Where do you hurt ? '' There was no response . Doering said Sunday that police think at least one person not in custody may have information in the case . Authorities have not released the identities or ages of the other victims , revealing only that they range in age from children through mid-40s . One additional victim was identified , Doering said Monday , but he did not release that person 's name pending notification of relatives . Autopsies on the victims began over the weekend in Savannah , Georgia , and continued Monday , Doering said . Police had been called to the home before , Doering said , but would not say why . He was tight-lipped Sunday about many aspects of the case , refusing to say how the victims died or to give a breakdown of male and female victims . All nine victims lived in the mobile home , he said , and police do not believe that any of them conducted the assault . He said police are making progress and have narrowed down the timeline for when the deaths occurred . Brunswick is about 300 miles southeast of Atlanta , on the Georgia coast .
