The hotel where Paul Gray died

This is the hotel where Paul Gray died.

It is called the TownePlace Suites Hotel, and it is located at 8800 Northpark Drive in Urbandale, Iowa.

Gray was a bassist and backing vocalist for the heavy metal band Slipknot.

His nicknames in the group were "#2" and "The Pig."

On the morning of May 24, 2010, Gray's mother, Nancy, called the TownePlace Suites Hotel to express concerns about her son's well-being.

At the time, Gray was in the throes of a serious drug addiction.

Although his family had recently attempted to stage an intervention, he refused to take responsibility for his behavior. His pregnant wife, Brenna, said he became "erratic" and upset when he learned she had hidden his drugs.

Following the failed intervention, Gray left his home and drove to this hotel on Northpark Drive.

This wasn't anything out of the ordinary, as the bassist often stayed at hotels whenever he and Brenna were experiencing relationship difficulties.

However, on this occasion, he failed to return home. He stopped answering his phone and responding to text messages.

Worried about the lull in contact, his mother contacted the hotel and asked them to perform a welfare check.

When an employee entered room 431, they found the 38-year-old slumped against a wall. It was apparent he was dead, as his skin had turned purple.

Various pills were scattered throughout the room, and a hypodermic needle was lying on the ground beside the bed.

An autopsy determined Gray died of an accidental overdose of morphine and fentanyl. There were also signs the musician had developed "significant heart disease."

Gray had struggled with drug addiction for years. His most recent relapse occurred two years prior to his death. His wife said he frequently relapsed when he was at home and not working.

Gray's longtime physician, Dr. Daniel Baldi, was later charged with involuntary manslaughter after it emerged he continued to prescribe the bassist Xanax and other drugs despite being aware of his substance abuse problems.

Dr. Baldi was found not guilty of the crime. However, he was later banned from prescribing controlled substances.
