Two-year-old Aiden McCarthy's photo was widely shared online earlier this week after he was found alone in the aftermath of a shooting, only for police to later confirm his parents were among the dead.

More than 41,000 people have donated to a campaign to raise money for a boy who was taken in by his parents.

Bill Ackman, the founder and CEO of Pershing Square Capital Management, gave the largest gift to date.

On Monday a man opened fire in Highland Park, a suburb of Chicago, killing seven people.
