( CNN ) -- A 36-year-old Atlanta woman whose body was found last month most likely died from exposure to cold , officials said Tuesday . The death of Stacey Nicole English , last seen alive shortly after Christmas , was classified an accident by the Fulton County Medical Examiner , which cited autopsy results , medical records and witness and acquaintance statements . Investigators used dental records to identify the remains found January 23 in a wooded area in southwest Atlanta . English 's abandoned car was discovered in late December , with the motor running . In a statement , the office said `` the most likely cause of death is cold exposure ( hypothermia ) complicating underlying neurological and psychiatric disorders . '' An autopsy indicated no injuries and toxicology results showed no evidence of a drug overdose . `` Because cold exposure is an external , environmental condition , the manner of death has been classified as accident , '' medical examiners said . A St. Louis man who had stayed with her December 24-26 , said English was `` acting peculiar and out of character '' during the stay , adding that `` she began screaming in the apartment and shouting biblical scriptures and indicating that the world was coming to an end , '' a police report said . He said that he left around 10:30 p.m. on December 26 , after English `` began asking him if he was Satan '' and told him to leave `` her residence immediately . '' A friend , Michelle Strothers , told police that she last saw English on that day or the next one . In an interview with police on New Year 's Eve , Strothers said that her friend `` appeared upset '' and told her `` she felt as if someone was attempting to hurt her . '' Earlier , English 's mother and stepfather told police that they typically talked with her `` several times a week '' and became worried after she did not answer their calls since they last talked with her on Christmas . Her mother , Cynthia Jamison , said that English `` was currently taking medication '' and had attempted suicide by overdose a little more than two years earlier , according to police . All six Fulton medical examiners participated in a peer review , the medical examiner 's office said . Atlanta police later Tuesday said they were closing the case , with no further statement planned .
Police conclude investigation . The police have a lot of information and they are working on it, but the case is still open. Medical examiner 's office says her death was an accident . It says she likely died of hypothermia .
