Teenage girl accused of killing parents pleads not guilty by reason of insanity





RHINELANDER, Wis. (AP) — A 17-year-old girl accused of killing her mother and stepfather has pleaded insanity in a northern Wisconsin courtroom.

Seventeen-year-old Ashlee Martinson pleaded not guilty by reason of mental disease or defect in Oneida County court Monday.

WSAW-TV (http://bit.ly/1Hr3y57 ) reports the court will appoint a psychologist to evaluate Martinson before her trial. Her next court appearance is Sept. 28.

She's accused of fatally stabbing her mother, 40-year-old Jennifer Ayers, and shooting 37-year-old Thomas Ayers at the family's home near Three Lakes last March.

Investigators say Martinson confined her three sisters in a room before fleeing to Indiana with her boyfriend.

Court documents say the Ayers were killed the same day they warned Martinson's 22-year-old boyfriend to stay away from her because she's a minor.

The sisters, ages 2 to 9, were not hurt.
