The husband of one of the teachers killed in Tuesday’s mass shooting in Uvalde, Texas, is believed to have died of a heart attack.
Joe Garcia was the husband of Irma Garcia, who taught for 23 years at Robb Elementary School.
Ms Garcia was one of two teachers killed by a teenage gunman in the shooting that left 21 people dead, including 19 children.
The couple – married for 24 years – are survived by four children.
As of Thursday evening, an online fundraiser for the Garcia family had raised nearly $1.6m (£1.3m) against a modest initial target of $10,000.
The GoFundMe page said it was organized by Ms Garcia’s cousin Debra Austin, who wrote: ‘I truly believe Joe died of a broken heart.
On Twitter, a nephew of Ms Garcia, John Martinez, said Mr Garcia had “passed away of grief” following the murder of his wife.
A local Fox affiliate reported that Mr. Garcia died of a fatal heart attack.
The Garcias leave behind four children – two boys and two girls – aged 12 to 23.
In the aftermath of the deadly shooting in Uvalde, Mr Martinez told The New York Times that Ms Garcia was found by officers ‘hugging children in her arms pretty much until she breathed her last’.
“She sacrificed herself to protect the children in her class,” he wrote on a fundraising page. “She was a heroine.”
Ms Garcia and the other teacher killed in the shooting, Eva Mireles, had taught together for five years and had more than 40 years of experience between them.
