A teenager accused of killing her mother and stepfather in northern Wisconsin is due in court.

Seventeen-year-old Ashlee Martinson has been brought back to Wisconsin from Indiana where she was arrested last month. Authorities say Martinson is scheduled for a Friday afternoon appearance in Oneida County Circuit Court.

Martinson is charged with fatally stabbing 40-year-old Jennifer Ayers and shooting 37-year-old Thomas Ayers on March 8 at the family's home in the Town of Piehl (peel).

Besides two counts of first-degree intentional homicide, Martinson is charged with three counts of false imprisonment. Prosecutors say she locked her three younger sisters, ages 2, 8 and 9, in a room before fleeing to Indiana with a 22-year-old man.

Investigators say the man was not involved in the crime.
