In a heartbreaking incident in Colorado, a 3-year-old boy was fatally struck by a hit-and-run driver while filming social media videos with older children, as reported by authorities and his mother. The boy’s mother, Shanice Silver, expressed confusion over how her son, Isaiah, managed to reach the steep embankment separating the road from their home.

Silver told the local Fox station KDVR that this was Isaiah’s first time on the embankment. “That’s the mystery we need to solve,” she said. “Even I find it difficult to get up there.”

According to the Erie police, Isaiah was discovered “lying in the roadway” near Mountain View Boulevard and Village Vista Drive. A passerby who noticed the child called for help and stayed at the location to assist law enforcement, as stated in a press release.

Emergency responders rushed to the scene and endeavored to save Isaiah, but unfortunately, he succumbed to his injuries.

In the aftermath, detectives examined surveillance footage from nearby areas and pinpointed a vehicle of interest linked to the tragic hit-and-run. The driver, who reportedly fled post-incident, remained at large as of Tuesday.

“No words can truly comfort the heartache of such a loss,” the Erie police commented.

Silver told KDVR that she heard a commotion while outside her home and went to check what was happening when she saw Isaiah in the roadway on the other side of the embankment, along with first responders.

“Our family experienced the kind of heartbreak no parent should ever endure,” a GoFundMe launched for Isaiah’s family says. “His mother, Shanice, and his father, Mitch, are living every parent’s worst nightmare — mourning the unimaginable loss of their baby boy. His brother, Elijah, and sister, Aiyana, are grieving the loss of their brother, a bond that was taken far too soon.”

Describing Isaiah, the GoFundMe says he was a “joyful, curious, radiant soul who filled every room with laughter,” per the description.

“Our family is completely heartbroken,” an aunt wrote on Facebook. “Please say prayers for our Silver children as they grieve the loss of their nephew and for mama and daddy Shanice and Mitchell.”
