  • Aggravated assaults by juvenile offenders are most common around 3 p.m. and sexual assaults by juveniles are most common at 8 a.m., noon, and 3 p.m.
  • Unlike the other violent crimes, the daily timing of robberies by juvenile offenders is similar to adult patterns, peaking in the late evening hours.
