Homicide was the manner of death in the case of 6-year-old Phillip Oliver “Ollie” Wiedemann, who was found dead in a Waxahachie parking garage in August.
Justice of the Peace in Ellis County Judge Steve Eagan told CBS 11 News the cause of death was “toxic effects of hydrogen sulfide.”

I know how I get Hydrogen Sulfide (Chemist) but I wasn’t sure about the general public.

Waxahachie city employee first spotted car at center of Amber Alert

After calling 911, police quickly arrived at the location. Iglesias says officers broke in a window and immediately reacted as if something was coming from inside it.
"Whenever we see them break the window, they all just step back real far and start like wafting the air around their face," Iglesias recalled. "It's kind of like the reaction if you've ever seen like a stink bomb go off."

There was also a hazmat response, though investigators have yet to detail what prompted the call-out. Police have revealed very little about the case, but they did say they are not looking for any suspects.

My older post BBM.
Evidently there was no note left on the car window for first responders.
So grateful the guy who called 911 and police were not exposed/hurt.

IMO
