Jeffrey Scott O'Donnell would disappear for months, lost in a fog of severe depression and alcoholism, with thoughts of suicide. But when he went to a meeting for recovering addicts in October, his mother "took that as a good sign."
Sherri O'Donnell, of Andover, asked her 42-year-old son that afternoon if he would be home for dinner.
"Why don't you go ahead without me?" she recalled him saying.
For Jeff, it was not an unusual response, she said. "We left the porch light on all night."
Until O'Donnell's frozen body was discovered Friday in an iced-over pond on a Ham Lake golf course, nobody apparently had seen or heard from him since Oct. 20.
Although an autopsy completed Tuesday showed "no anatomic cause of death, no injury or trauma," the Anoka County Medical Examiner's office said it would continue its study. Results of a toxicology report are not expected for days.
O'Donnell was hospitalized at Unity Hospital for having suicidal thoughts in January 2007, his mother told Coon Rapids police later that year. He left a suicide note, blood drippings and a knife in his Coon Rapids apartment before disappearing in September of that year, according to a police report. A building manager also found several cases of beer in O'Donnell's kitchen after O'Donnell was reported missing more than three months later.
"We'd report him missing and the police would say, 'He's 42 years old!' Nobody was going to search for him," said Michael O'Donnell, his father. "After a while, we stopped reporting him missing."
