An investigative report shows that staffers at a juvenile detention center in Maryland left a teenage resident unsupervised with a teacher for more than an hour on the day the teacher was killed.
A boy, who was 13 at the time, has been charged as a juvenile in her death.
A report released by the Department of Juvenile Services Inspector General said staffers at Cheltenham could not account for his whereabouts for more than an hour the day before Wheeling's body was found.
It also said staffers made minimal efforts to determine Wheeling's whereabouts late that night after discovering that her car was still on the campus.
Wheeling was killed in a section of the youth facility for juveniles who need court-ordered supervision but aren't deemed dangerous.
