In August 2015 Limerick man Jason Corbett was murdered by his wife, Molly Martens, and her father, ex-FBI agent Tom Martens, in the bedroom of their luxury North Carolina home. He had been savagely beaten to death with a baseball bat and brick while his children slept nearby. For his sister, Tracey Corbett-Lynch, and the rest of his family in Ireland it was just the beginning of the nightmare that would involve a custody battle for his orphaned children, an online hate campaign by Molly Martens and, ultimately, the gripping trial that would lead to her conviction, alongside her father, for his murder. My Brother Jason is the story of how this seemingly all-American girl from a picture-perfect family targeted the widowed Jason Corbett, becoming nanny to his children in a desperate bid to create the family and security she craved, thus setting in motion a series of events that would lead to Jason's brutal killing by the woman he had once loved. Here, for the first time, Tracey Corbett-Lynch tells her family's side of the story in a book that contains shocking revelations about Molly Marten's history of strange behaviour and the lengths she was willing to go to in order to get custody of Jason's children. With full access to Jason's letters, emails, keepsakes and photographs, it is the story of how an ordinary, loving family was torn apart by the brutal murder of their beloved brother.
