Police say that driver was involved in a road rage incident with another vehicle.
Livingston was riding his bike on the Northwest Side and was hit when one of the drivers lost control.
On Tuesday night, ABC7 reported police were going to review video from a nearby camera to look for clues. Police now have that video and the Medical Examiner ruled Jepson Livingston's death a homicide.
It was around noon on Tuesday when Jepson Livingston was riding his bike in the 3800-block of West Diversey.
Witnesses say two vans where speeding down the street when one veered into the bike path and hit Livingston. Police say the driver kept going, stopping only after crashing into an auto repair shop.
Survellence video captured the scene.
"They came right over flying through the street, like through the fence, the iron fence," said Javier Medina, witness.
Medina owns the shop. He says after the van crashed three adults including the driver and a child got out of the van and took off. Moments later, the video shows one of those people returning to the van for some unknown reason.
Medina says it could have been worse because his workers had just finished making repairs to the gate the van crashed through.
"He was missed for like two seconds. Otherwise he would have been run over by the fence and the van. So he would have been dead also," said Medina.
Ed Ziemba, Livingston's uncle, says his nephew was a happy go lucky person with a good soul. But recently he had suffered some hardships and he was out looking for a job when he was killed.
Ziemba says he was just in the wrong place at the wrong time.
"I'm sure someone seen something. There's the police cameras right on that corner also. The police are looking into it," said Ziemba.
Medina says the crash caused more than $3,000 of damage to his property.
Police have told the family to expect charges in the next 24 hours.
