A dead child has been found at the side of a road after a driver initially mistook it for 'baby doll'.
The grim discovery was made on an interstate highway in Arkansas.
Police responded to a welfare check after someone reported they may have seen a doll shortly after 9am on Tuesday. It was then that the body was found.
Reports describe the victim as being a 'young child'. No age, identity or cause of death have been released.
It comes as police probe three other road deaths involving kids in the space of just five hours.
Special Agents of the Arkansas State Police Criminal Investigation Division are not linking the tragedies.
The incidents happened along two U.S. highways in Jackson and Saline Counties
Two young siblings were found dead just after 4am near the 98 mile marker of U.S. Highway 67 south of the Jackson and Craighead County line.
The victims have been identified as Michael Rogers, III, 10, and his sister, Princess Josh-Lyn Logan, three.
The children were apparently struck by a southbound tractor-trailer commercial carrier driven by Gerald Sanders, 77. Sanders was not injured, police said.
Latoya Taylor, 26, the mother of the children was found at the fatality scene when state troopers arrived, but she was not physically injured.
In an unrelated incident, at 8.53am state troopers responded to a call from a motorist reporting a young child had been dropped from a moving vehicle along the westbound lanes of Interstate 30 near the 117 mile marker in Saline County.
The child, believed to be around two years old, died after troopers were on the scene and awaiting emergency medical care to arrive.
CID special agents are questioning witnesses in each case.
Cabinet Secretary Jami Cook said: "Agents have been in contact with prosecuting attorneys in both local jurisdictions and will submit criminal case files for consideration whether to file formal charges in the deaths.
"No arrests have been made in either case at this time."
