REGINA - The Crown says a Regina woman convicted of second-degree murder in the death of a little girl should serve at least 18 to 20 years of her life sentence before being eligible for parole.

Prosecutor Kim Jones says the woman's husband, convicted of manslaughter, should be sentenced to life with no chance of parole for seven years.

Jones is also suggesting eight years for Tammy and Kevin Goforth for unlawfully causing bodily harm to the dead girl's younger sister.

But the defence says Tammy Goforth should be eligible for parole in 10 years and her husband should be sentenced to no more than between 30 months and eight years for manslaughter.

The sisters were in the Goforths' care in the summer of 2012 when the girls were taken to hospital and found to be malnourished, dehydrated and with bruises on their bodies.

The four-year-old died a few days later from a brain injury after suffering cardiac arrest; her two-year-old sister survived.
