The death of singer Jill Sobule investigated for drug signs, alcohol

Jill SobuleDeath is received a meticulous examination of investigators … because they try to determine when she died – and if drugs, alcohol or carbon monoxide played a role.

A representative of the Ramsey County Legalist in Minnesota told TMZ … The investigators dig in the cause and the manner of Jill's death – and, a major detail, the investigators try to determine is if she was still alive when a house fire broke out, where she was found later dead.

Remember that Woodbury Public Safety received a call for an active house fire around 5:30 am Thursday … with the first speakers arriving to find the house entirely swallowed up in flames.

The firefighters actively fought against the fire while looking for a missing person – Sobule – that the owners believed inside … But, when they finally found it, Jill was already deceased.

The Ramsey County Medical Representative also tells us that – in order to determine if she succeeded before the fire, or because of this – Jill is tested for drugs, alcohol and carbon monoxide poisoning.

The manager and Jill's agent confirmed his death yesterday … remembering Jill as a “force of nature and the human rights defender whose music is woven in our culture”.

Sobule the best known for his 1995 “I Kissa a Girl”, “Supermodel” of the film “Clueless” and the theme song of Nickelodeon “Unbulous”.

She was 66 years old.
