Plymouth, Massachusetts —

The prosecution in Lindsay Clancy’s triple-murder trial rested its rebuttal case and testimony is now over as the case moved toward its final stages.

The final witness was an FBI psychiatrist who said Clancy could still appreciate right from wrong and control her behavior when she killed her three children. He pointed to her “preparatory planning,” which included conducting searches on her phone, mapping the distance from their home to a restaurant, and then committing the killings in the timeframe when her husband was out of the home.

“The fact that this was done without any witness present during a time where she had asked a potential witness to go on a longer errand – also I thought was significant,” Dr. Gregory Saathoff said.

Closing arguments, jury instructions and deliberations are expected Thursday.
