A 20-year-old Calgary woman has been found guilty of killing her own mother.

The jury, consisting of nine women and three men, deliberated for two days before acquitting Brittany Jewel Mahingen of second degree murder.

Mahingen was found guilty of manslaughter in the death of her mother, Leanne.

Leanne Mahingen was found dead in a downtown apartment where the two were babysitting in November of 2009.

Brittany Mahingen cried and bit her fingernails as the verdict was read. Sentencing is scheduled for Friday May 18.
