In the aftermath of a mass shooting that left seven dead Monday in a Chicago suburb, a toddler wandered alone before strangers picked him up and began searching for his parents. Tuesday, it emerged both his parents were killed in the gunfire, leaving the 2-year-old an orphan.

Anguish took over the city of Highland Park in a wave after Fourth of July celebrations were shattered when a gunman opened fire, injuring at least two dozen people. Among those killed were a dedicated synagogue worker, an avid bird watcher and a grandfather watching Fourth of July festivities from his wheelchair.

Hundreds gathered at a vigil downtown Tuesday evening as neighbors held hands, hugged and cried. Some placed flowers, prayed and lit candles. Many wore Highland Park High School sweatshirts.

“It feels good to be with other people going through the same thing,” said Lucy Melinger, 19, who lives a block from the scene of the shooting, as she carried a bouquet of pink carnations.

TODDLER ORPHANED AFTER ATTACK:How Highland Park stepped in to help

All but one victim have been identified by The Lake County Coroner’s office:

  • Katherine Goldstein of Highland Park, 64
  • Irina McCarthy of Highland Park, 35
  • Kevin McCarthy of Highland Park, 37
  • Jacquelyn Sundheim of Highland Park, 63
  • Stephen Straus of Highland Park, 88
  • Nicolas Toledo-Zaragoza of Morelos, Mexico, 78

Here’s what we know so far about them. 

Irina McCarthy, 35, and Kevin McCarthy, 37

Irina McCarthy’s childhood friend, Angela Vella, described McCarthy as fun, personable, and “somewhat of a tomboy” who still liked to dress up. “She definitely had her own style, which I always admired,” Vella told The Associated Press.

Born in Moscow, Irina McCarthy moved to Chicago with her family when she was 2 years old before later moving to Highland Park, her father, Michael Levberg, told the Chicago Tribune on Tuesday. Irina and Kevin McCarthy got married about five years ago after they met while working together, he said.

They were the parents of 2-year-old Aiden, who was found bloody and alone by bystanders. His photo was shared across social media and news outlets with a plea to identify him. He was reunited with his grandparents Monday evening.

Friends of the McCarthys said Irina’s parents would raise him going forward. Meanwhile, community members mobilized to help support the boy, raising almost $2 million for him by Wednesday morning on GoFundMe. 

“At 2 years old, Aiden is left in the unthinkable position; to grow up without his parents,” a verified GoFundMe page for Aiden said.

Nicolas Toledo, 78

Nicolas Toledo was among was among the people killed at a shooting during a Fourth of July parade in Highland Park, Illinois, his granddaughter, Alba Toledo, 23, confirmed to USA TODAY.

Nicolas Toledo, 76, was among the victims, his granddaughter, Alba Toledo, 23, confirmed in Spanish in a message to USA TODAY, adding their family is “shattered.”

“It’s an enormous pain,” she said.

“Believe me my grandfather was a great person, with an enormous heart, he was the best grandfather, loving, attentive,” she added.

He wasn’t sure he wanted to go to the parade, but his family — who had excitedly set up chairs along the parade route the night before — brought him to the event to watch in his wheelchair, another of his granddaughters, Xochil Toledo, told the Chicago Sun-Times.

When shots rang out, Xochil Toledo said her father tried to shield her grandfather, but Nicolas Toledo died at the scene of the shooting.

Toledo, a great-grandfather and dual Mexican-American citizen, spent most of his life in Morelos, Mexico, and had moved back to Highland Park a few months ago to be with family, Xochil Toledo told the Sun-Times. It is unclear if he is the Mexican national that an official from the Mexican Foreign Ministry’s North America unit said was among the victims.

He had eight children, a big smile and bright, blue eyes, Xochil Toledo told the Sun-Times. He liked a home-cooked meal and had a great sense of humor. Alba Toledo told USA TODAY her grandfather loved drawing, hunting, fishing and going for walks in the park.
