EDWARDSVILLE — A Belleville man who died Saturday was inhaling compressed gas air dusters just before his death, the Madison County Coroner’s Office said Monday.
In a press release, Coroner Stephen P. Nonn said an investigation continues into the death of Sean P. Sobczak, 47, who had been reported missing by his family.
Collinsville police officers found Sobczak on Friday inside a running vehicle in the parking lot of the Collinsville Walmart. It appeared he was inhaling, or “huffing,” compressed gas air dusters. He was arrested for driving under the influence. After being transferred to the Collinsville Police Department, he began to complain of shortness of breath and an ambulance was summoned at 4:45 p.m.
Sobczak was transferred to Anderson Hospital in Maryville. His condition deteriorated through the night and he was pronounced dead at 5:17 a.m. Saturday.
An autopsy conducted Sunday revealed the presence of cardiac disease. Alcohol and drug testing remains pending. Sobczak’s medical history, which included diabetes and hypertension, also will be evaluated prior to determination of an exact cause of death. Funeral arrangements are pending.
