Teen accused of killing parents waives extradition

TOWN OF PIEHL, Wis. (AP) -- A 17-year-old northern Wisconsin girl accused of killing her mother and stepfather will soon be extradited from Indiana.

The Oneida County sheriff's officials said Friday Ashlee Martinson has agreed to return to Wisconsin where she's 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.

Martinson is also accused of locking her three younger sisters, ages 2, 8 and 9, in a room before fleeing to Indiana with a 22-year-old man. Investigators have not publicly talked about what may have motivated the crime, but say it appears the defendant acted alone.

The Oneida County Sheriff's Department has 30 days to arrange Martinson's transportation to Wisconsin from Boone County, Indiana.
