"The defendant was 16 years old at the time of the deadly fentanyl deliver and showed a callous disregard human life, leaving a friend to overdose and die, alone on a sidewalk in Ripon. This is a devastating loss for the victim’s family and our thoughts and prayers go out to all the families that have lost a loved one to fentanyl.
