Nancy Kerrigan Supports Brother Mark in Court

A heartbroken Nancy Kerrigan arrived for the start of her brother's manslaughter trial.  

The Olympic skater clutched her husband's hand tightly outside court. She was dressed casually in slacks and a windbreaker.

Her 46-year-old brother Mark, a troubled ex-con, is charged with attacking their 70-year-old father Daniel during a violent argument last year.

Nancy comforted her mother Brenda as the 911 call was played in court for the first time.  

911 Operator: "What's your emergency?"
Caller: "My husband is on the floor, and I don't really know what's wrong with him."
911 Operator: "What happened to him?"
Caller: "Oh my God, I hope he's not dead! Oh my God! Oh my God! Oh my God!"

Massachusetts prosecutors say Daniel Kerrigan suffered a fatal heart attack as a result of the fight.

"Daniel Kerrigan died at the hands of his 45-year-old son," the prosecutor told the court.

But the defense says Daniel Kerrigan's death was a tragic accident, caused by a pre-existing heart condition.   

Nancy is expected to be called as a prosecution witness against her brother, even though she and the rest of the Kerrigans are standing by him.

She's led a quiet life since the infamous moment when she was clubbed on the knee before the 1994 Olympics.  

Now she faces an equally painful ordeal, testifying against her own brother, who's charged with killing their father.
