WELLINGTON, Kan. (AP) — A south-central Kansas woman has been convicted of fatally beating and stabbing her 10-year-old son to death in his bedroom.

Lindsey Nicole Blansett of Wellington was found guilty Tuesday in Sumner County of first-degree murder in the December 2014 death of her son, Caleb Blansett.

Wellington police say the boy had gone to bed on Sunday when Lindsey Blansett entered his room with a rock and knife. She is accused of hitting him with a rock before stabbing him several times.

She told police she was concerned about her son’s future and wanted him to “go to heaven tonight.” She underwent mental exams and was deemed competent for trial.
