A semi rear ended a construction vehicle on I-94 killing a construction worker from Knox, Indiana, according to Indiana State Police.

Police responded to the 23 mile marker on I-94 in the eastbound lanes just before 3 a.m. Friday.

An investigation revealed a semi was eastbound when it drove onto the right shoulder and rear ended a 2017 Dodge Ram, owned by Traffic Control Specialists.

The driver of the Ram stepped out of the driver's side of the truck just as it was rear-ended by the semi, reports said.

The worker, 38-year-old Ryan E. Greer, from Knox, died at the scene.

The pickup truck was pushed into a ditch and into the trees off the road. A passenger in the vehicle was not injured.

As the semi continued east, it crossed all lanes of traffic, struck the median and burst into flames, reports said.

Police said the driver of the semi was not injured.

All of the cargo in the trailer, 37,000 pounds of frozen pork, was lost in the fire.

Formal charges or citations are pending the outcome of the investigation and will be determined by the Porter County Prosecutor’s Office.
