Crime / Nancy Kerrigan Nancy Kerrigan's Dad's Death a Homicide: DA Charges against Olympic figure skater's brother may be amended By Marie Morris, Newser Staff Posted Feb 9, 2010 1:38 PM CST Copied Daniel and Brenda Kerrigan, parents of 1994 Olympic silver medalist Nancy Kerrigan, outside their home in Stoneham, Mass., Feb. 10, 1994. (AP Photo/Susan Walsh, FILE) The death of Nancy Kerrigan's father was a homicide, but the DA in the case hasn't decided whether to charge the Olympic figure skater's brother with murder. Mark Kerrigan was charged with committing assault and battery against their 70-year-old father just before he died. He pleaded not guilty and has been under psychiatric observation since shortly after Daniel Kerrigan's death on Jan. 24, the Boston Globe reports. Cardiac arrest killed Daniel Kerrigan "following a physical altercation with neck compression causing injury to the neck," according to the medical examiner in Middlesex County, outside Boston.
