Shaquanda Cotton, the black teenager in the small east Texas town of Paris whose prison sentence of up to 7 years for shoving a teacher's aide sparked nationwide controversy, was released Saturday morning.

Her release, ordered by a special conservator appointed to overhaul the state's scandal-ridden juvenile prison system, is the first of what could be hundreds as a panel of civil rights leaders begins reviewing the sentences of every youth incarcerated by the Texas Youth Commission to weed out those being held arbitrarily.

"We have no confidence in the system that was in place," said Jim Hurley, spokesman for the conservator, Jay Kimbrough. "And this case is an example of what we expect to happen if something wrong has been done to youths being held inside that system."

Cotton, who is 15, had no prior criminal record when she was incarcerated a year ago under an indeterminate sentence that could have lasted until her 21st birthday. Her case rose to national prominence and became the focus of ongoing civil rights protests after a March 12 Tribune story detailed how a 14-year-old white girl convicted of the more serious crime of arson was sentenced to probation by the same judge.
