A synagogue teacher, a Mexican grandfather, and the parents of a two-year-old found wandering alone after a deadly attack on a July 4 parade in a Chicago suburb were among the victims of the latest US mass shooting.
Irina McCarthy, 35, and Kevin McCarthy, 37, were killed when a rooftop sniper fired on Monday's parade.
As well as the seven fatalities, about 50 people suffered gunshot wounds and other injuries, police and hospital officials said.
The toddler, named Aiden, was separated from his parents in the ensuing chaos and was later returned to family members by police, according to a fundraising page.
"He will have a long road ahead to heal," said Irina Colon, who organized the GoFundMe page with the family's permission, adding that his grandparents would care for the boy.
The fund has raised more than $US425,000 ($A628,000) so far.
Another victim was Nicolas Toledo, 78, visiting from Mexico when he was shot at the parade alongside relatives, some of whom were wounded but are expected to survive, according to local media.
Jacki Sundheim, 63, a teacher at a Highland Park synagogue, was also killed, leaving behind a husband and daughter.
Other victims identified by authorities included Katherine Goldstein, 64, and Stephen Straus, 88.
Thirty-nine people were taken to hospitals run by NorthShore University HealthSystem, ranging in age from 14 to in their 70s, said spokesman Jim Anthony. Nine remain hospitalised.
A 69-year-old man is in a critical condition with a gunshot wound.
Nine people were treated by Northwestern Medicine Lake Forest Hospital, six for gunshot wounds, three for falls, said spokesman Christopher King.
Four remain hospitalised, with their conditions ranging from good to fair.
