A former preschool teacher and a beloved grandfather are among the victims of a deadly July Fourth parade shooting

Now, yet another community in America is processing their grief as they mourn the loss of family and friends after a suspected shooter used a “high-powered rifle” in an attack that appeared to be “random” and “intentional,” police said.

Here’s what we know about the lives lost:

Jacki Sundheim

The North Shore Congregation Israel in Glencoe said in a statement Sundheim was a lifelong congregant and a member of the staff, having been a preschool teacher and events coordinator.

“There are no words sufficient to express the depth of our grief for Jacki’s death and sympathy for her family and loved ones,” the statement said. “We know you join us in the deepest prayer that Jacki’s soul will be bound up in the shelter of God’s wings and her family will somehow find comfort and consolation amidst this boundless grief.”

Nicolas Toledo

Father of eight and grandfather to many, Nicolas Toledo, 78, had been visiting his family in Highland Park from Mexico and was identified as a victim in Monday’s shooting, an official from the state of Morelos told CNN.

Mexican officials issued a press release identifying Toledo as Nicolas “N,” a customary practice in Mexico where authorities use “N” for any last name in official documents, under a law for human rights and protection of privacy of victims.

“What was suppose(d) to be a fun family day turned into a horrific nightmare for us all,” the organizer of the GoFundMe and another granddaughter, Xochil Toledo wrote. “As a family we are broken, and numb.”

She described her grandfather as a “loving man” who was “creative, adventurous and funny.”

Six of Toledo’s eight children live in the United States, according to the statement from Mexican authorities. One was injured in the shooting alongside two other members of the Toledo family.

What we know about the wounded

Barbara Medina, 46, was injured in the shooting — not by gunfire, but by the stampede as parade-goers fled the area in an effort to escape the chaos on Monday.

Medina was marching in the parade holding a banner for Community Partners for Affordable Housing (CPAH) when she heard gunshots ring out, she told CNN. A sea of people rushed toward her, so she dropped the banner, grabbed her 7-year-old daughter Caroline and her scooter, and ran. Unfortunately, she was separated from her 12-year-old son and her father in the mad dash to get away from the area.

Medina and her daughter fled down an alley but noticed her daughter slowing down behind her. She reached back to grab her and help her along, but tripped on her scooter and fell hard on her left arm. She knew immediately it was broken, she said.

“I could see it went the wrong way, and I had to kind of maneuver it back,” she said. “It was very painful.”

After making it to a stranger’s home, Medina learned her son and father were safe and sheltering elsewhere. She borrowed a sling and an ice pack, and propped her arm up on some pillows to relieve the pain.

Hours later, Medina went to Skokie Hospital, a non-trauma facility, to get her arm looked at and doctors diagnosed her with a broken proximal radius just below the elbow. She now has a cast from the tips of her fingers to the top of her shoulder, and expects to be in a cast for about 6 to 8 weeks.

Though her arm is sore, she’s thankful she and her family weren’t seriously injured.

“I’m more worried for the kids. I’m just grateful that we’re all safe,” she said. “It’ll be a long healing process.”
