A two-year-old boy traveling with his mother fell from her car and was fatally hit by another vehicle on Saturday, resulting in the Missouri woman being charged with first-degree child endangerment, per multiple reports.

Authorities are yet to establish how little Elijah Roby fell out of the vehicle on Friday afternoon in St. Louis County, Daily Mail reports.

Ebony Roby, his mother, put the boy inside the vehicle immediately after the incident and drove to a Shell gas station on Lucas and Hunt before calling 911. The child was rushed to hospital in critical condition after dispatch received a report of the incident on Jennings Station Road at 4.48 pm. 

Speaking to KMOX News Friday night, Sergeant Shawn McGuire said, "The driver of the vehicle remained on scene. They're cooperating with investigators. Detectives are trying to piece together the scene while trying to interview as many witnesses as possible." Little Elijah, however, succumbed to his injuries.

St Louis County Police Department investigators mentioned that Ebony was arrested on Saturday and that she was cooperating with them. As the Bureau of Crimes Against Persons probed into the incident, the embattled mother was placed on a $50,000 bond, according to KMOV.

Showing sympathy for the detained woman, Roby's school friend Tarisha Warren posted a call to raise $10,000 on a GoFundMe page in a bid to help cover funeral and related costs. "I went to school went ebony and I swear I feel this to my heart shouldn't no mother have to go through this!" Warren wrote. "Things happen ‍♀️ , God, I ask you to give this mother and her family the strength for this tragic lost I'm a mother myself♥️ jah jah . I made my donations and wish I could of given more for baby Eliajah." 

Patrabean Edwards, a family member who set up the crowdfunding page, called the incident a "tragic loss." According to Edwards, little Elijah had half a dozen other siblings. However, it is unclear if they all belong to his mother.

"Our 2-year-old nephew Elijah Roby, whose life had barely began, was lost in an accident," Edwards wrote. "He leaves behind his grieving mother, father, several sisters and brothers and Family who are in need of your help with funeral arrangements and supporting the future needs of his 6 other siblings. We greatly appreciate anything u can give, even a prayer. We love you all and Thank you."
