Chief Deputy Coroner Dan Pruitt said Stumpf also had evidence of ephedrine, a stimulant used for weight loss and also as a nasal decongestant, in his system. Testing also revealed a metabolite of cocaine, suggesting cocaine use and evidence of THC, pointing to marijuana use.

There is no medical conclusion on his death yet, including whether Stumpf had a heart attack, or whether he had suffered a seizure or was unconscious at the time of the crash.
