Hong Kong’s Court of Final Appeal ruled Thursday that the murder trial of Nancy Kissel was flawed and ordered that she be held in custody while undergoing a new trial.
Kissel’s lawyers had argued that prosecutors used improper evidence to challenge her credibility during her trial in 2005. In those proceedings, Kissel was sentenced to life in prison.
Kissel, dubbed the “milkshake murderer,” was convicted of giving her husband a sedative-laced milkshake and then clubbing the Merrill Lynch & Company banker to death in 2003.
Kissel admitted that she killed her husband, saying he was abusive.
Prosecutors argued that Kissel planned the attack, and noted that her husband was worth $18 million in life insurance, investments and properties.
