A GoFundMe page has raised more than $2 million for a boy whose parents were killed earlier this week during an Independence Day shooting at a parade in the US state of Illinois.

The son of Kevin McCarthy, 37, and Irina McCarthy, 35, was separated from his parents during the chaos Monday that left seven people dead and more than 30 others injured in Highland Park.

The donation for the 2-year-old boy hit $2.3 million Wednesday -- well above the goal of $500,000.

"Sadly, I need to share his name…Aiden McCarthy. And he needs more of our help. His parents Irina & Kevin were killed during the July 4 shooting. At two years old, Aiden is left in the unthinkable position; to grow up without his parents," said the organizer of the campaign, Irina Colon.

"Aiden will be cared for by his loving family and he will have a long road ahead to heal, find stability, and ultimately navigate life as an orphan," said Colon.

Police arrested suspected shooter Robert E. Crimo III, 22, late Monday.

The gunman purchased the firearm legally and fired more than 70 rounds into the crowd. He was dressed in women's clothing to mix with the crowd in an attempt to escape, according to law enforcement officials.

He used a high-powered rifle to fire bullets from the roof of a building into the crowd that was celebrating independence day. The firearm was recovered at the scene.

President Joe Biden ordered the US flag at the White House flown at half-staff and on all public buildings and grounds as a mark of respect for the victims./aa
