Police in south-central Kansas have charged a woman who they say stabbed her 10-year-old son to death in his bedroom.

Thirty-three-year-old Lindsey Blansett of Wellington is being held at the Sumner County Jail on $500,000 bond. She is charged with first-degree murder in the 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. They say she struck him with the rock and stabbed him multiple times in the chest.

The Wellington Daily News reports a 9-year-old girl in the house was taken into protective custody on Monday and released to family members.

No other injuries were reported.

It wasn’t immediately clear if Blansett has an attorney.
