WOBURN, MASS. (CNN)—The brother of Olympic figure skater Nancy Kerrigan was acquitted Wednesday of involuntary manslaughter, but was convicted of assault and battery for an altercation with his father that preceded his father's death in 2010.
Mark Kerrigan showed little emotion as the verdict was read in Middlesex Superior Court in Woburn, Massachusetts, as his sister looked on.
Judge Jane Haggerty is expected to preside over a sentencing hearing scheduled for Thursday.
Prosecutors say Daniel Kerrigan, 70, died after having an argument and physical confrontation with his intoxicated son.
A medical examiner had found that Daniel Kerrigan's death came from cardiac dysrhythmia triggered by the brawl, which resulted in a larynx injury. Cardiac dysrhythmia is abnormal electrical activity in the heart.
Previously, Kerrigan's family members said Daniel Kerrigan had a heart condition.
