The mother of an infant who died two years ago says her plea bargain deal to testify at her former boyfriend’s manslaughter trial wasn’t motivated by her desire to serve less time in jail.

Jane Gomes said today at the trial of Ashiqur Rahman that her testimony against her former partner is true, and she isn’t testifying because she got immunity from a manslaughter charge.

Gomes told the trial by judge alone in the Supreme Court of Nova Scotia that she is taking responsibility for mistakes she made in not telling public health nurses that she saw Rahman slap and shake their baby.

The 25-year-old Rahman has pleaded not guilty to manslaughter and aggravated assault in the July 2009 death of the couple’s seven-week-old daughter, Aurora Breakthrough.

Gomes pleaded guilty last year to a charge of failing to provide the necessities of life and received a conditional discharge with six months of probation.

A neuropathologist has testified that Aurora suffered extensive brain injuries prior to her death at a Halifax hospital
