Mother's testimony details Clancy's mental decline before deaths of her three children

A Plymouth mother testified that her daughter Lindsay Clancy deteriorated mentally over three months before strangling her three children in January 2023. Clancy reportedly told her mother, "this isn't me," expressed thoughts of harming the children, and said she could no longer remember things. Clancy pleads not guilty by reason of insanity—a defense arguing she was unable to understand her actions.
