Trial Begins For Brother Of Skater Nancy Kerrigan

Update: On Monday, a Massachusetts jury listened to an emotional 911 call in the manslaughter trial of Olympic skater Nancy Kerrigan's brother.

Nancy Kerrigan's mother, Brenda, can be heard sobbing and pleading with a dispatcher to send help quickly for her husband, 70-year-old Daniel Kerrigan.

Brenda Kerrigan tells the dispatcher he fell to the floor. At one point, she is heard yelling, "Get away from him!"

Her son, Mark Kerrigan, gets on the phone and tells the dispatcher he thinks his father has had a heart attack.

A prosecutor has told Massachusetts jurors that the 70-year-old father of Olympic skater Nancy Kerrigan spent the last few minutes of his life fighting off his angry, drunken 45-year-old son.

Assistant District Attorney Elizabeth Keeley said the physical violence by Mark Kerrigan put Daniel Kerrigan's heart into what's known as cardiac dysrhythmia - a loss or interruption of a normal heartbeat.

Mark Kerrigan's defense lawyer, however, told the jury that Daniel Kerrigan died because he had severe blockage of arteries leading to his heart, not because of the physical altercation with his son.

The lawyers gave opening statements to the jury in Mark Kerrigan's manslaughter trial.

Nancy Kerrigan and her family have supported Mark Kerrigan. They've said Daniel Kerrigan died of a longstanding heart condition.
