When the Mind Breaks - Inside the Clancy, Simms, and Greist Cases

from Koltergeist: True Crime Stories

Some of the most devastating intersections of mental illness and violence occur in cases that are unthinkable-when parents killed their children while experiencing episodes of active acute psychosis.In this episode of Koltergeist, we discuss just 3 of the many stories of fractured reality—where delusions overrode instinct. We examine what psychosis looks like in deeply unwell parents and how when symptoms go unrecognized or misunderstood, they can lead to irreversible outcomes-cases of filicide-where a parent kills their own child.Mental illness does not discriminate by age, race, gender, income, or education. It can take root in any home, unravel any mind, and alter anyone’s life. These cases will challenge our most basic ideas about intent, culpability, compassion, and justice.These are stories of Lindsay Clancy, Romechia Sims, and Richard Greist.Episode Sources:Oct 26, 2023, page A5 - The Republican at Newspapers.com™Oct 16, 2024, page B4 - The Boston Globe at Newspapers.com™ - Newspapers.com™Lindsay Clancy's Husband Speaks Out After Killings, Says Wife Isn't a 'Monster'Lindsay Clancy hearing weighs psych records and reporter's notes | Court TVPostpartum Psychosis - StatPearls - NCBI BookshelfSep 15, 2015, page 4 - The McDowell News at Newspapers.com™ - Newspapers.com™Apr 23, 2016, page A2 - Lexington Herald-Leader at Newspapers.com™ - Newspapers.com™Jun 07, 2015, page A25 - The News Journal at Newspapers.com™ - Newspapers.com™May 11, 1978, page 1 - The Morning Press at Newspapers.com™ - Newspapers.com™Jan 23, 1980, page 35 - Philadelphia Daily News at Newspapers.com™ - Newspapers.com™Aug 03, 2022, page B3 - The Philadelphia Inquirer at Newspapers.com™ - Newspapers.com™May 12, 1978, page 1 - The Reporter at Newspapers.com™ - Newspapers.com™https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2787197 Hosted on Acast.
