Ashlee Martinson

Ashlee Anne Rose Martinson (born March 6, 1998) is an American woman convicted of the 2015 murders of her mother and stepfather, which she committed the day after her 17th birthday. Martinson's case received international attention.

Background Ashlee remained estranged from her biological father and lived with her mother, stepfather, two stepsisters and a half sister. She had moved to Rhinelander, Wisconsin with her family at age sixteen.

During her interviews, experts believed she has post-traumatic stress disorder and depression. Her car and phone privileges were revoked after the argument.

When first interviewed, Martinson claimed it was not her, but her mother, who had killed Thomas Ayers and she was attacked upon finding her mother standing over the corpse of her stepfather and killed her mother in self-defense. Her younger sibling's statements to police disputed these claims. Martinson later said she had taken the gun to commit suicide, but was interrupted by Thomas Ayers.

Police were called to the scene on March 8 by the oldest stepsister of Martinson and they immediately suspected Martinson was responsible, due to the fact that she had fled the scene. After police announced the details of the crime and their vehicle information, she and Sisco were captured in Boone County, Indiana. Sisco was never considered a suspect in the case, but was charged for a parole violation. The motion was denied by judge Michael Bloom in September. In 2019, an appeals court denied her a new trial.
