PIEHL, Wis. (March 10, 2015) – A Wisconsin teenager arrested in Indiana on Sunday is accused of killing her mother and stepfather.

Ashlee Martinson, 17, will face two counts of first-degree intentional homicide and three counts of false imprisonment, according to the Wausau Daily Herald. The 17-year-old was arrested Sunday in Boone County after a deputy spotted her car.

According to court documents, Martinson killed Jennifer Ayers, 40, and Thomas Ayers, 37, before locking her three sisters in a room and leaving the home. Her 9-year-old sister told police she was with her mother when they heard gunshots upstairs. Jennifer Ayers then went upstairs, where she and Martinson argued and fought.

The 9-year-old said Martinson then told her and her two other sisters that they were going downstairs to play a game. Martinson put the girls in a room and tied the door shut so they couldn’t get out, the newspaper reported.

Investigators said they don’t have a motive in the case.

Ryan Sisco, Martinson’s boyfriend, was arrested with her in Indiana on Sunday. Investigators in Wisconsin said Sisco is not wanted in connection with the homicide case.
