WELLINGTON, Kan. (AP) — A Kansas woman accused of killing her 10-year-old son will undergo a mental competency hearing in May.

During a brief court hearing Thursday in Sumner County, an attorney for 33-year-old Lindsey Nicole Blansett said he wanted to question a psychologist who evaluated Blansett before a judge decides whether she is fit to stand trial. She is charged with first-degree murder in the Dec. 14 stabbing death of Caleb Blansett at the family’s home in Wellington.

The hearing was set for May 14.

The Wichita Eagle reports  that a criminal complaint in the case alleges Blansett decided Caleb’s life would be full of suffering and it would be better for him to go to heaven. She called 911 to report the stabbing.
