UPDATE 4:16 p.m. Friday, Oct. 18. - A Rackerby man was sentenced to the maximum prison term in Butte County Court on Friday, Oct. 18.

65-year-old William Mandril was sentenced on charges of felony vehicular manslaughter with an allegation of death and injury to two additional victims.

District Attorney Mike Ramsey said Judge Clare Keithley sentenced Mandril to the maximum term of six years in state prison. Mandril was also ordered to pay $29,331.67 in restitution to the victims.

The case against Mandril began when CHP officers were sent to the scene of a multiple-vehicle collision on Lower Wyandotte road near Foothill Blvd. south of Oroville.

The investigation revealed Mandril’s car crossed the center line on a curve in the road and struck two other cars, one of which was disabled, parked on the opposite shoulder.

Mandril struck three people who had stopped to help the disabled vehicle, killing 20-year-old Hillary Wilhite, of Oroville and injuring the other two.

"The CHP officer on the scene reported Mandril failed a series of field sobriety tests, had difficulty staying awake, refused alcohol screening at the scene and claimed to have no memory of the accident, said Ramsey. "Evidence at the scene indicated that after the collision, Mandril attempted to discard a large bag of marijuana and other drug paraphernalia prior to law enforcement’s arrival.

Further investigation revealed the presence of methamphetamine, oxycodone, carisoprodol and meprobamate in Mandril’s blood, but no alcohol.
