SALT LAKE CITY -- Dozens of emergency crews responded to the scene of an apparent suicide Monday morning because of the possibility of a hazardous substance.
Police and paramedics arrived at 750 West and 1950 South and found the body of a man in a car. He was dead from a gunshot wound to the head.
Crews also found instructions for a chemical.
"There was a diagram found that indicated possible hydrogen sulfide, which is a common form of suicide that is circulating the Internet," said Mark Bednarik of the Salt Lake City Fire Department. "So, that caused us a little bit of pause."
Hydrogen sulfide can cause illness or even death in cases of severe exposure.
Hazmat teams were called in to search the scene but could not find any sign of the chemical.
The suicide victim has not been identified.
