Jill Sobule‘s tragic passing is currently under intense investigation by authorities … as they are working diligently to ascertain the exact time of her death and whether substances such as medication, alcohol, or carbon monoxide exposure played a role in this heartbreaking incident.

A representative from the Ramsey County Medical Examiner’s office in Minnesota stated to TMZ that investigators are thoroughly examining the circumstances and causes surrounding Jill Sobule’s death. A critical factor in their investigation is determining whether she was still alive at the time of a house fire that later resulted in her being discovered deceased.

It is important to note that the Woodbury Public Safety received an urgent call regarding an active house fire around 5:30 AM on Thursday. When first responders arrived at the scene, they were confronted with a home that was completely engulfed in flames, raising significant concerns about the safety of anyone inside.

Firefighters bravely battled the raging blaze while simultaneously searching for a missing individual — Jill Sobule — whom the homeowners believed was still inside the residence. Unfortunately, upon their eventual discovery, they found that Jill had already passed away.

The representative from the Ramsey County Medical Examiner’s office also indicated that investigations are underway to determine whether Jill passed away before the fire incident or as a direct result of it. To assist in this evaluation, her body is being examined for traces of drugs, alcohol, and carbon monoxide poisoning.

Both Jill’s manager and her agent confirmed the heartbreaking news of her passing to us yesterday, remembering her as a true force of nature and a dedicated human rights advocate whose music has profoundly impacted our culture.

Jill is best known for her iconic 1995 hit “I Kissed a Girl,” as well as the catchy “Supermodel” from the film “Clueless,” and the memorable theme song for the Nickelodeon show “Unfabulous.”

She was just 66 years old.
