Carrie Carolyn Coco: My Friend, Her Murder, and an Obsession with the Unthinkable

An NPR Best Book of the Year ● An Oprah Daily Best Book of the Summer ● A Chicago Review of Books Must-Read Book of the Month

Acclaimed author Sarah Gerard turns her keen observational eye and penetrating prose to the 2016 murder of her friend Carolyn Bush, examining the multi-faceted reasons for her death―personal and societal, avoidable and inevitable.

“Sarah Gerard redefines true crime in this poignant tribute to her friend . . . using in-depth reporting to expose the privilege and misogyny at the heart of this case.” —NPR


“Astonishing. . . . What stuns about Carrie Carolyn Coco is . . . the intricate ways in which Sarah Gerard unravels poison in the dark corners of Carolyn Bush’s world: a fancy liberal arts college with a chilling history of violence; the violence in Bush’s everyday existence; the web of people who are willing to stand up for Bush’s murderer, some with dubious motives.” ―Esmé Weijun Wang, New York Times bestselling author of The Collected Schizophrenias


On the night of September 28, 2016, twenty-five-year-old Carolyn Bush was brutally stabbed to death in her New York City apartment by her roommate Render Stetson-Shanahan, leaving friends and family of both reeling. In life, Carolyn was a gregarious, smart-mouthed aspiring poet, who had seemingly gotten along well with Render, a reserved art handler. Where had it gone so terribly wrong?

This is the question that has plagued acclaimed author Sarah Gerard and driven her obsessive pursuit to understand this horrific tragedy. In Sarah’s exploration of Carolyn’s life and death, she spent thousands of hours interviewing Carolyn's and Render’s friends and family, poring over court documents and news media, reading obscure writings and internet posts, and attending Carolyn’s memorials and Render’s trial.

What emerged from Sarah’s relentless instinct to follow a story and its characters to their darkest ends is a book that is at once a striking homage to Carolyn’s life, a chilling excavation of a brutal crime, and a captivating whydunit with a shocking conclusion.

I kept starting and stopping this book because it was a slightly rough ride and also, because I am a chronic book juggler. I loved it, though - I think Gerard's achievement was in creating a book that was true crime but truly highlighted the victim's life above any kind of glamourization of the murderer or the crime. I know that is a recurring criticism among those who feel that true crime stories are often exploitative, and this didn't feel like that at all. Although I certainly learned a bit about Carolyn's killer and about the things that played a role in making him who he was, I felt I learned much more about Carolyn herself. I came away from this book awash in the loss of her, although I never knew her. I could imagine the heartbreak those who loved her would feel acutely because Gerard really paints her as a whole complete person with dreams and potential. I think that's really amazing - this book is such a tribute, and I applaud what it does.
