But on Thursday, the last vestiges of the story appeared to come tumbling down after law enforcement officials in New Jersey announced theft charges against all three individuals: the couple, Kate McClure and Mark D'Amico, as well as Johnny Bobbitt, the homeless man they said they were going to support with the money that had flowed in.
Kate McClure and "Johnny" are seen in a photo posted on the GoFundMe page she started for him.
It wildly exceeded its original goal of $13,750, and Coffina said that, after GoFundMe's fees, it brought in $504,629.
"The entire campaign was predicated on a lie", Coffina said. But Bobbitt became homeless again after D'Amico told him in June he had to leave.
"He walked up and he said, 'Get back in the vehicle".
A source with access to a criminal complaint in the case reportedly told NBC 10 that all three are expected to face charges of conspiracy and theft by deception.
According to investigators, McClure had also texted a friend admitting what portions of their story were fake shortly after the fundraising page was created.
In other texts, the couple discussed their inability to pay bills and their mounting debts.
The story spread like wildfire online, and resulted in hundreds of thousands of dollars in donations being sent from people who wanted to also help Bobbitt Jr.
D'Amico has said Bobbitt spent $25,000 in less than two weeks previous year on drugs as well as paying for overdue legal bills and sending money to family. I didn't think anything about it.
GoFundMe plans to reimburse the 14,000 donors, who contributed US$403,000, the prosecutor said.
"Rather, D'Aminco, McClure and Bobbitt conspired to fabricate and promoted a feel-good story that would compel donors to contribute to their cause", he said.
All three have since been taken into police custody, including Bobbitt, who was arrested in Philadelphia.

Nearly as famous as his Marvel superheroes , Lee was known for bringing complex emotional life to cartoon characters. The Marvel co-creator and publisher made dozens of TV and movie cameos in the Marvel universe , dating back to 1989.
If proven in court, the crimes carry sentences between five and 10 years.
But then McClure and D'Amico changed their story, stating through legal counsel that there was no money left.
GoFundMe and the law firm representing Bobbitt issued a joint statement last week saying he would receive all the money raised for him. Campaigns with misuse make up less than one tenth of one percent of all campaigns. "GoFundMe always fully protects donors, which is why we have a comprehensive refund policy in place".
According to its website, the company has a Trust and Safety team that reviews GoFundMe campaigns around the clock and works to prevent fraud.
Last fall, social media was abuzz with the story of McClure and D'Amico's seeming act of kindness. He was certain the payday from the book deal they were pursuing would dwarf the money generated by the GoFundMe campaign.

It's not exactly clear what happened with the money, though Bobbitt's attorney has said it's all gone.
But questions about the money soon followed.
The heartstring-tugging tale worked, as donations started pouring in for Bobbitt, with the viral campaign's haul eventually blowing past $400,000.
A lawyer for the couple initially said that only $150,000 of the initial $401,921 remained. Coffina told reporters that he believes the couple met Bobbitt near a local casino that they frequented.
At the time, the Burlington County Prosecutor's Office confirmed the search was related to the allegations Bobbitt had levied against the couple.
Investigators searched the couple's home and hauled away a BMV vehicle that they had recently purchased.
