PONTIAC, Mich. (AP) — A judge in Michigan who’s under criticism for detaining a 15-year-old girl after she failed to do her schoolwork has denied the teen early release. The Detroit News reports that Oakland County Circuit Court Judge Mary Ellen Brennan said during a hearing Monday that the girl was placed in a juvenile facility because she was a threat to her mother. ProPublica reported last week that the girl has been in Oakland County’s Children’s Village since mid-May for violating probation in a case involving allegations of assault and theft. Brennan had cited a “failure to submit to any schoolwork and getting up for school.”
