And then on Jan. 25, 2010, Brenda Kerrigan called 911 to report that her husband had fallen. The 911 operator – hearing a commotion - asked whether there was fighting in the background and Brenda Kerrigan said, "Oh, yes." Mark Kerrigan took the phone and told the operator his father "seemed to have a heart attack."
Daniel Kerrigan was pronounced dead at Winchester Hospital a short time later.
The prosecutors initially charged Kerrigan with assault but upgraded the charges a short time later. When asked today if they overreached in charging Mark Kerrigan with involuntary manslaughter, DA Gerald T. Leone Jr. said "I know we charged this case right … under the facts, under the law." And, Leone added, "Daniel Kerrigan wouldn't be dead if not for the actions of Mark, an angry, belligerent, intoxicated 45-year-old man."
The messy family history has left many scratching their heads, wondering why Brenda and Nancy Kerrigan would remain so supportive of Mark Kerrigan given the events of that night and his history. The two women have always maintained that they loved Mark Kerrigan and did not hold him responsible for his father's death.
And during the trial Janice Bassil, Kerrigan's defense attorney, said simply that her client loved his father.
Tomorrow Mark Kerrigan will be back in court to hear his sentence on the assault-and-battery.
