The Milan Post of the Ohio State Highway Patrol (OSHP) has concluded its investigation into a massive pile-up along the Ohio Turnpike, this month.
Authorities say they conducted fifty different crash investigations involving damage to 126 vehicles.
According to OSHP, 49 people reported being injured in the March 12 incident that also killed three people.
Among those injured was an Ohio State Highway Patrol Trooper, Andrew Clouser, who became pinned between two vehicles.
Officials also determined that two biggest crash areas occurred along "the eastbound side of the roadway between mile posts 101 to 102".
In that area, six separate crashes took place due "to the severe blowing snow making for limited visibility".
Overall, OSHP said that "causative factors" for many of the crashes was that drivers were "following too close and [at an] unsafe speed for the weather conditions".
Among the crashes along the eastbound side, in the area designated by OHSP, 55 vehicles were involved.
In those 55 vehicles, 36 people were hurt and three people were killed.
Trooper Clouser was also critically injured on the eastbound side of the Turnpike.
The Ohio State Highway Patrol concluded their report with a reminder to drivers to "slow down and increase following distances during inclement weather".
