Ailing former warden won't have to testify at inquest into Ashley Smith death

TORONTO - A former prison warden won't have to testify at the coroner's inquest into the death of teenager Ashley Smith because of illness.

Brinda Wilson-Demuth was scheduled to appear Tuesday.

However, coroner's counsel said Wilson-Demuth is ailing and the lawyers have decided they won't be calling her as a witness.

Other witnesses have testified the former warden of Grand Valley Institution in Kitchener, Ont., ordered records altered to avoid scrutiny from higher-ups.

Smith, 19, of Moncton, N.B., choked herself to death in her segregation cell in October 2007 as guards stood by.

Another senior prison manager, Joanna Pauline, is slated to testify Wednesday.
