“A hearing is scheduled in Plymouth Superior Court Friday where Lindsay Clancy is being prosecuted for murdering her three children in her Duxbury home in 2023, records show. Those details appeared to be aimed at challenging defense assertions that Clancy was overmedicated at the time of the killings. Blood tests found three antidepressants, an antipsychotic, two sedatives, and an anticonvulsant medication, Sprague said. The tests detected the antidepressant trazodone at a level too low to have an effect on Clancy, Sprague said. It also turned up the presence of the antidepressant amitriptyline but couldn’t pinpoint how much Clancy had consumed, she said.
