The Nancy Kissel murder case (officially called the Hong Kong Special Administrative Region v Nancy Ann Kissel) was a highly publicised criminal trial held in the High Court of Hong Kong, where American expatriate Nancy Ann Kissel (née Keeshin) was convicted of the murder of her husband, 40-year-old investment banker Robert Peter Kissel, in their apartment on 2 November 2003. It was arguably the highest profile criminal case involving an expatriate in Hong Kong's history, and was closely covered in the media.
Kissel was convicted of murder in 2005 and received a mandatory life sentence. The Court of Final Appeal overturned the conviction in February 2010, citing legal errors, and ordered a retrial. At the conclusion of the retrial on 25 March 2011, Kissel was again found guilty of her husband's murder and sentenced to life in prison. She is serving her sentence at Tai Lam Centre for Women.
