Nationwide, fewer minors between the ages of 10 and 17 years old are being arrested, according to figures from the U.S. Department of Justice. That includes minors accused of violent crimes like murder, rape and aggravated assault. Christopher Vogler, director of probation services at Pima County Juvenile Court, said national trends parallel what is happening in the county. According to Vogler, over the last two decades the number of minors transferred to adult court for prosecution has dropped from about 200 cases per year to between 60 and 70. He also discussed the developmental impact of prosecuting minors as adults.
