Kevin Goforth, who was found guilty of manslaughter in relation to the death of a four-year-old in his care, has filed an appeal of his sentence of 15 years. After he was given credit for time served prior to his conviction, Goforth has 14 years remaining on his sentence.

He began serving that time in February after a jury determined he was guilty of manslaughter in relation to the child's death, which was due to severe malnutrition that led to cardiac arrest. Goforth was also convicted of causing bodily harm to the girl's younger sister.

The sentence was imposed by the judge overseeing the case.

Goforth's handwritten appeal, using a standardized form, was filed with the Saskatchewan Court of Appeal Wednesday.

In the section of the form stating the reason for the appeal, Goforth said the sentence was too high and was "harsh" and excessive.

Goforth, 39, is not seeking an appeal of the conviction itself.

His wife, Tammy Goforth, who was convicted of second-degree murder and causing bodily harm in the same case, has also filed an appeal. She was given a life sentence with no chance of parole for 17 years. Tammy Goforth is appealing both her conviction and sentence.

The children had been in the Goforth's care for several months.

According to testimony heard by the jury, the girl who died was suffering from malnutrition and was in cardiac arrest when she arrived at Regina General Hospital in the summer of 2012. Her brain was damaged as a result of the heart attack. Two days after being taken to hospital, on Aug. 2, the child was taken off life-support and died.

The girl's sister, who was two at the time, also needed hospital treatment. She survived.
