It was later revealed that Turnbull and his brother, Horace, the choir's executive vice president, allowed Jones to stay in contact with students even after city officials explicitly banned him from the 650-student academy (a public school that is overseen and financed in part by the Department of Education).
A city school official reported to investigators that Horace Turnbull had complained to her that barring Mr. Jones was "a hardship," because he was "an integral part" of the program.
That fall Jones was arrested, tried and sentenced to two years in prison for multiple counts of third-degree sexual abuse and endangerment of a child.
In 2003, city investigators concluded that the Turnbull brothers had failed to report the complaints of abuse to the authorities and had allowed Mr. Jones to continue working with children.
As a result, the city school system's investigative arm recommended that the Department of Education "sever all ties" with the academy if the Turnbulls remain.
