NORRISTOWN (AP) — A Pennsylvania man who authorities say was driving his pickup truck at 101 mph (163 kph) while under the influence of marijuana when he struck and killed a man riding a lawn tractor says he made a “huge mistake.”

A judge in Montgomery County on Wednesday sentenced Christopher Bailey to 1½ to 7½ years in prison. The judge called the 21-year-old’s actions “extremely reckless.”

Bailey had pleaded guilty to homicide by vehicle and driving under the influence of a controlled substance in the 2017 crash that claimed the life of 70-year-old Randall Wampole.

Wampole’s wife, Susan, told the court “one moment we were trimming a bush in our front yard and in a matter of seconds Randy was gone.”
