A 30-year-old woman has been arrested two days after a toddler was seen being thrown from a moving car, and died while first responders were waiting for paramedics.

KATV reports that Whitney Turner-Tyson was arrested on Tuesday night, though authorities did not confirm this until late the next day.

The report indicates that the Saline County Sheriff’s Office made the arrest. Turner-Tyson has been charged with capital murder, first degree battery and endangering the welfare of an incompetent person.

As CrimeOnline previously reported, a witness called police on Tuesday morning to say they saw what may have been a baby doll being dropped from a moving vehicle on Interstate 30 in Saline County. When police officers responded to the witness’s welfare check request, they found a child of about 2 years old. According to local reports, the child was alive initially but died before it could be transported to a hospital.

Authorities have not released the child’s name, or confirmed the relationship between the child and the woman in custody.

Earlier Tuesday morning, two children were killed in a separate incident when they were run over by a tractor-trailer while standing in the lane of traffic on a highway in another part of the state. An Arkansas State Police source told CrimeOnline on Wednesday that that incident is also the focus of a criminal investigation.

Turner-Tyson is reportedly being held without bond at the Saline County jail.

CrimeOnline will provide further updates when more information is available.
