I'm about 100 miles from there...ugly situation. But, from what I can tell from the time I've spent in juvi court, it's all too typical. Social media is amazing to me, in that kids have no respect for the fact that anything put online is out there to everyone. In some ways, it's worse than saying it out loud, because it may never go away. Don't understand the whole texting photo thing either, but I am amazed by how many kids and adults do this without a second thought.
Back to the OP, Ohio law has juvi punishments like this:
Misdemeanor - up to 90 days in a detention center (jail for juvis)
Felony 5,, 4, or 3 - 6 months to age 21 in a Dept. of Youth Services facility (juvi prison)
Felony 2 or 1 - 1 year to age 21 in a DYS facility.
Release dates for felonies is determined by the DYS release authority, who allegedly evaluate a juvenile's treatment progress then makes a decision after the minimum date. Reality is tha the kida get released as soon as they can justify it.
To be tried as an adult, it must be an offender 14 or older, the offense must be a serious felony, and the juvi court must find that the juvenile offender is not amenable to treatment in the juvenile system. While it's not written, it is understood that short of a murder charge, a juvenile must have a prior felony record and DYS time to be sent to adult court. Of course, there are provisions for an autommatic bindover if the juvenile uses a firearm to commmit a felony.
