TOWN OF PIEHL, Wis. (AP) — A Wisconsin teen accused of killing her mother and stepfather carried out the slayings the same day they warned her 22-year-old boyfriend to stay away from her, according to court documents made public Friday.
Ashlee Martinson, 17, was formally charged in Oneida County after being brought back from Indiana, where she was arrested last month.
She is accused of fatally stabbing 40-year-old Jennifer Ayers and shooting 37-year-old Thomas Ayers at the family’s home in town of Piehl. Investigators say Martinson locked her three sisters, ranging in age from 9 to 2, in a room before fleeing their rural home.
The Stevens Point Journal reported that Martinson appeared in court by video from the county jail, and sat silently beside her attorney. She has not entered a plea.
The court documents made public Friday outlined a series of events that included several 911 hangups from a cellphone before dispatchers could reach a 9-year-old girl at her house. Officers who went to the scene found the three young children and the Ayerses’ bodies.
One of Martinson’s sisters told investigators that the couple had learned Martinson was dating the 22-year-old. The girl said Thomas Ayers came home March 7 and went upstairs and pounded on Martinson’s door. The girl said she then heard two gunshots. Then Jennifer Ayers went upstairs.
The daughter said she went to the stairs and saw her mother and sister fighting, with Martinson on top. The girl said Martinson told her to go downstairs, which she did, and she heard her mother stop screaming. She said Martinson then came down and told the girls to watch cartoons on TV.
Martinson was arrested in Indiana with her boyfriend, Ryan Sisco. He later told investigators he had been messaging with people he believed to be Martinson’s parents on Facebook the day authorities believe they were killed, and he was warned to stay away from Martinson because she was a minor, according to the documents.
