"It just hurts so bad", Brown's grandmother, Alice, told the newspaper. William Brown, who according to his grandmother suffered from asthma issues, died at John Peter Smith Hospital on January 29, two days after the horrific incident and just weeks before his birthday.
She said she doesn't understand why the hospital didn't operate.
It's presently unclear what brand of vape pen William purchased at the Keller store.
The Tarrant County medical examiner listed Brown's death as an accident caused by "penetrating trauma from exploding vaporizer pen" that dissected his left internal carotid artery. She had to go through it to find the pieces of the destroyed vape pen and said she managed to find the key piece - the battery showing the serial number.
"Now he's got a new address in heaven", Alice Brown said.
She told CBS DFW that Tarrant County investigators said the cause of the malfunction was a faulty battery. "And that's what they should have taken out as soon as he got to the hospital, and they chose to wait until Monday or Tuesday". His family told the local TV station that doctors at JPS Patient Care Pavilion knew he had a piece of e-cigarette lodged in his throat but never operated on him.
He had asthma and had been told that there was a certain vape pen that could help with his symptoms.
His grandmother said Brown was a certified electrician and took "good care" of her and her family.
A spokeswoman for the JPS Health Network said she could not comment on specifics due to privacy laws, but said the company is continuing to communicate with Brown's family and expressed their honest condolences. The FDA said the incidents resulted in 133 acute injuries, 29% of them severe.
That changed in May 2018, when a 38-year-old man in Florida died after a vape pen exploded in his face, shooting parts of the pen into his brain and setting his house of fire.
Brown was rushed to the hospital where he was put into a medically induced coma.
E-cigarettes and vape pens are battery-operated devices that heat a liquid to create an aerosol that can be inhaled like regular cigarette smoke.
The Food and Drug Administration haswarned about the dangers of exploding e-cigarettes.
