A truck driver has been convicted on dozens of charges — including vehicular homicide — for a major fatal pileup crash that occurred in Colorado in 2019.

On Friday, 25 year old Texas resident Rogel Lazaro Aguilera-Mederos was found guilty on 27 charges, including four counts of vehicular homicide, six counts of first-degree assault, ten counts of attempt to commit assault in the first degree- extreme indifference, two counts of vehicular assault- reckless, one count of reckless driving, and four counts of careless driving causing death.

Aguilera-Mederos had previously pleaded not guilty to 41 charges, arguing that mechanical failure was to blame for the crash.

Sentencing is scheduled for December 13.

The charges were issued as a result of a fatal chain reaction crash that happened in slowed traffic on I-70 near Lakewood, Colorado, on April 25, 2019.

Aguilera-Medero reportedly hit speeds of 85 m.p.h. in an area where trucks are limited to 45 m.p.h and lost control of his brakes before crashing into slowed traffic.

The pileup involved 24 passenger vehicles and four semi trucks.

Four people died in the crash and six others were injured.

Video taken by a motorist shows that Aguilera-Medero bypassed a runaway ramp prior to the fatal crash.
