We should take a step back and look at what we know and what we don’t. Police and prosecutors say Mr. Harris had stolen three cars during the winter. In March, while awaiting trial on those charges, he was sent to a non-secure juvenile facility in Montgomery County — essentially a group home — but prosecutors say he walked out and stole another car. He was arrested, and on March 13, officials from the Department of Juvenile Services picked him up and returned him to the Baltimore City Juvenile Justice Center. While his cases were being sorted out, he spent some time at another shelter in Catonsville. He failed to appear in court on April 16. The next day, he was arrested and, per DJS’ recommendation, was sent back to the secure Baltimore Juvenile Justice Center.
