The crimes occurred about a month before his 21st birthday.
He was charged with three counts of forcible lewd act upon a child and one count of false Imprisonment by violence, menace, fraud or deceit. On May 31, two months later, he pleaded guilty to two counts of forcible lewd act and the single count of false imprisonment.
Gardner faced a maximum prison sentence of 10 years and 8 months. On September 13, 2000 he was sentenced to six years in state prison, and ordered to pay a $1200 fine.
In the sentencing summary, prosecutors considered Gardners actions extremely predatory, and this makes him very dangerous despite his minor prior record. When combined with his callous attitude and refusal to admit any wrongdoing, defendant demonstrates that he is an extreme danger to others and needs to be imprisoned to protect society.
The court records indicate that the district attorney did not seek the maximum sentence only because Gardner had no significant record of prior criminal conduct.
