Irma's cousin, Debra Austin, had also confirmed Joe's death on the verified GoFundMe page intended to help the Garcia family.
"Please keep our family in your thoughts and prayers. I truly believe Joe died of a broken heart and losing the love of his life of more than 25 years was too much to bear."
The GoFundMe page was created with a goal of raising USD10,000 (S$13,705) for the Garcia family.
But as of Friday (May 27) afternoon (Singapore time), over USD1 million were raised.

According to BBC, the Garcias were married for 24 years.
