A 4-year-old has died after being hit by a car when he walked into a roadway overnight Sunday in Florence, Kentucky.

It happened around 12:59 a.m. when the Boone County Sheriff’s office said deputies were called out to a crash on the Weaver Road overpass along I-75.

The sheriff’s office said a driver was traveling west when she struck the 4-year-old who had walked into the roadway from the right shoulder.

The 4-year-old, who the sheriff’s office identified as Jamison Beck, from Florence, died Monday at Cincinnati Children’s Hospital.

The driver of the vehicle was not injured, officials say.

Deputies say the female driver noticed a vehicle had stopped in the eastbound lane of travel and flashed their headlights, resulting in the vehicle slowing down to approximately 30 mph in a 55 mph posted zone.

Officials say the vehicle that had stopped had passed through the area and saw the child standing at the edge of the roadway on the overpass unsupervised and turned around and stopped in traffic to make contact with the child when the collision happened.

Officials say the female driver did not see the child walk into the roadway, due to nighttime conditions and the roadway being unlit. She did stay on scene, according to deputies.

BCSO officials say the 4-year-old, who is autistic and nonverbal, left his residence from a nearby apartment complex on Mission Lane after their family had gone to sleep.

According to deputies, speed and alcohol or drug impairment have been determined to not have been factors in the crash, and the driver and the child’s family are cooperating with the investigation.

No charges have been filed, officials say.

Florence police are leading the investigation.
