The medical examiner says D'Elia's cause of death was listed as "projectile wound of head".
The autopsy report for Tallmadge D'elia says shrapnel from his exploding vape pen killed him.
An autopsy reported released Tuesday blames the man's vape pen for his injuries. He suffered burns to 80 percent of his body. The death was ruled an accident.
Vape pens are electronic cigarettes that produce vapor that users inhale.
The report blamed the incidents on the prevalence of lithium-ion batteries in the products. At the time of his death, D'Elia was using a "mod" type of Smok-E Mountain Mech Works pen that was manufactured in the Philippines.
The owner of Lizard Juice, an e-cigarette retailer in Florida, said he does not think such vaping pens are "safe enough".
The exact causes of e-cigarette explosion incidents sometimes are unclear, but evidence suggests that battery-related issues may lead to explosions, according to the US Food and Drug Administration. Wilder told ABC Action News that he, as well as many other local store owners, won't sell unregulated e-cigarettes.
There were 195 separate e-cigarette fire and explosion incidents in the United States reported by the media between 2009 and 2016, according to data released a year ago by the US Fire Administration.
In 2016, a vaping device blew up in a man's face in NY - knocking out his teeth, ripping a hole in his tongue and leaving his hands covered in burns.
There have been other cases of exploding e-cigarettes, but none of them were fatal.
