A 59-year-old Stapleton woman is facing vehicular homicide charges in a crash that killed her daughter and seriously injured her granddaughter.

On the morning of November 26, Lincoln County deputies responded to an injury accident at Mile Marker 87 on Highway 83, north of North Platte.

Authorities say a minivan being driven by Vicky Allen, crossed the center line and collided with a semitrailer.

Allen’s daughter, 34-year-old Michelle Heisz, was killed in the crash and her granddaughter, three-year-old Angellycka, was seriously injured.

A warrant was recently issued for Allen’s arrest after a toxicology report was returned, showing that multiple prescription drugs were found in her system at the time of the crash.  Officials say Allen did not have a prescription for these narcotics and determined that their effects would impair her ability to drive.

According to jail records, Allen turned herself in on April 20.

She’s been charged with negligent vehicular homicide, driving under the influence (causing serious bodily injury), and felony possession of a controlled substance.

Allen is being held on ten percent of $50,000 bond.
