Attorney Compares Defense Strategy to Lindsay Clancy Case
Thomas Keniff draws parallels between the circumstances of a mother accused of killing her child and his defense of Daniel Penny.
Attorney Thomas Keniff has drawn parallels between his defense of Daniel Penny, a Marine veteran accused in the subway death of Jordan Neely, and the case of Lindsay Clancy, a mother charged with killing her three children. Keniff stated that he has defended a "deranged mom who had killed her baby" and described the similarities to the Clancy case as "chilling." He also recalled a "horrific video" he will not forget in relation to the case.
Keniff represented Penny, who was accused of recklessly choking to death Neely on a New York City subway in 2023. The case garnered significant public attention and sparked debates about mental health, public safety, and vigilantism. Penny was ultimately acquitted of manslaughter in November 2023. IMAGE4
The case of Lindsay Clancy, a former nurse from Massachusetts, also captured national attention. Clancy was accused of strangling her three young children in January 2023 while suffering from postpartum psychosis. Her defense team argued that she was not criminally responsible due to severe mental illness. IMAGE6 
In Clancy's situation, her psychosis appeared to have been triggered by a self-help book her adult brother brought home a few days earlier. IMAGE2
Arguments in Clancy's case centered on whether she was legally insane at the time of the killings. Some suggested that Clancy could not have been psychotic because she was too methodical in her planning to kill her three children. IMAGE3
The Clancy trial ultimately ended in a mistrial in November 2023. The case has raised profound questions about mental health care, particularly for new mothers, and the legal definitions of insanity and criminal responsibility. Keniff's commentary suggests he sees echoes of the complex legal and ethical issues presented in the Clancy case within his own professional experiences. IMAGE1
