In what is believed to be one of the first deaths from an e-cigarette malfunction, a 38-year-old man in Florida was killed when his vape pen exploded, sending projectiles into his head and causing a small fire in his house.

Tallmadge D’Elia was found May 5 in the burning bedroom of his family’s home in St. Petersburg, according to the Tampa Bay Times. An autopsy report released his week blamed a vape pen explosion for his death, local news outlets reported.

The cause of death was listed as “projectile wound of head” — the pen exploded into pieces, at least two of which were sent into his head, the Pinellas-Pasco Medical Examiner said — and he suffered burns on about 80 percent of his body.
