( CNN ) -- The medical examiner has ruled that the death of Daniel Kerrigan , the father of figure skater Nancy Kerrigan , was a homicide , the Middlesex County district attorney 's office said Tuesday . The skater 's brother , Mark , was arraigned in January on assault and battery charges in an incident involving his father , but the district attorney 's office would not say if other charges might be filed against the younger Kerrigan in light of the medical examiner 's finding . Daniel Kerrigan , 70 , died January 24 after an alleged altercation with his son at the Kerrigan home in Stoneham , Massachusetts . The Kerrigan family released a statement through their attorney expressing disappointment `` that the medical examiner would release a cause of death without having all of the relevant facts . We believe this finding to be premature and inaccurate . '' `` The Kerrigan family does not blame anyone for the unfortunate death of Dan Kerrigan , who had a pre-existing heart condition , '' said the family statement , released by attorney Tracy Miner . Mark Kerrigan , 45 , pleaded not guilty to the charges against him January 26 . Through his attorney , he denied any responsibility in his father 's death . According to Middlesex County Assistant District Attorney Elizabeth Keeley , police responded to a 911 call at approximately 1:30 a.m. January 24 from Brenda Kerrigan , wife of Daniel and mother to Mark and Nancy Kerrigan . Keeley told District Court Judge Mark Sullivan during the arraignment for Mark Kerrigan that there was a violent argument and struggle between the father and his son , resulting in the elder Kerrigan falling or collapsing on the kitchen floor . Keeley said Mark Kerrigan told authorities `` that he did in fact have an argument with his father , the argument became physical , he grabbed his father around the neck , and at some point the father collapsed to the floor . '' According to Keeley , police found Mark Kerrigan in the basement of the house , `` clearly intoxicated '' and `` extremely combative . '' He refused to comply with police officers , said Keeley , and they had to subdue him with pepper spray before forcibly removing him from the home . Mark Kerrigan 's attorney , Denise Moore , said in court that Kerrigan was unemployed , was recently released from a correctional facility and was living at home with his parents . He is taking medications and seeking psychological help for post-traumatic stress , apparently from his time in the Army , she added . Despite appeals from his attorney , the judge ordered Kerrigan held on $ 10,000 cash bail . His next court appearance is expected to be February 24 . Nancy Kerrigan first gained prominence by winning a bronze medal at the 1992 Winter Olympics in Albertville , France . In 1994 she earned a silver medal in Lillehammer , Norway . But she is perhaps best remembered for being injured in an attack before the 1994 Winter Games by skating rival Tonya Harding 's ex-husband and an accomplice .
