Aiden McCarthy GoFundMe Hits $2M for Boy Orphaned By Highland Park Shooting

More than $2 million in donations have been raised for a two-year-old boy whose parents were both killed in Monday's shooting at a July 4 parade.

Aiden McCarthy's photo was shared on social media in the hours after the shooting in Highland Park, Illinois, along with calls to help identify the child who had been found at the scene alone.

Parade attendees Dana and Greg Ring told CBS News that they found Aiden with a stranger after the shooting and took him in.

"She was physically shaking, her whole body," Dana Ring said. "Which told us that ... she shouldn't be having to hold, and/or deal with a little one at the same time."

The boy was picked up by a detective and reunited with his grandparents on Monday evening. And on Tuesday, authorities confirmed that his parents—Kevin McCarthy, 37, and Irina McCarthy, 35—were among the seven people killed in the shooting.

"At two years old, Aiden is left in the unthinkable position; to grow up without his parents," said Irina Colon on a GoFundMe page she created for McCarthy on Tuesday.

"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. He is surrounded by a community of friends and extended family that will embrace him with love, and any means available to ensure he has everything he needs as he grows," Colon said.

Colon wrote that she had set up the fundraising page with the family's permission to raise funds to support the boy and his caregivers.

More than 34,000 donations have been collected on the page in less than 12 hours. As of early Wednesday, the total raised was more than $2 million.

"My heart breaks for you, your family, and all the victims and their families of this horrific tragedy," one donor wrote. "We're all looking out for you. You're our family now."

Colon has been contacted for additional comment.

Four of the other victims have been identified: Katherine Goldstein, 64; Jacquelyn Sundheim, 63; Stephen Straus, 88; and Nicolas Toledo-Zaragoza, 78.

The seventh victim has not yet been identified. At least 30 others were wounded in the shooting.

Authorities said the suspected gunman had used an AR-15-style rifle to allegedly fire into a crowd that gathered for a parade in the Chicago suburb from atop a commercial building.

Robert Crimo III was arrested on Monday evening and has been charged with seven counts of first-degree murder.

If convicted of the murder charges, Crimo would receive mandatory life sentence without the possibility of parole, Lake County State's Attorney Eric Rinehart said at a news conference on Tuesday.

But he said more charges would be sought.

"These are just the first of many charges that will be filed against Mr. Crimo. I want to emphasize that," he said.
