Mark Kerrigan's Mental State Questioned

The father of figure skater Nancy Kerrigan was remembered by family and friends at a funeral Thursday as a family man who went out of his way for his three children and as a key to his daughter's accomplishments.

Daniel Kerrigan is the one who famously carried his injured daughter after she was attacked prior to the 1994 Winter Olympics.

More than 100 people attended a private service at St. Patrick Church in Stoneham. Friends and family paid tribute through somber readings and praise, and Jim Day, a family friend, eulogized Kerrigan by saying he set an example to his children and always put his family first.

"When God made Danny, I wish he never threw away the mold," Day said. "If we had more people like Danny Kerrigan in the world, there would be peace and love everywhere."

Day also pleaded with attendees to pray for Kerrigan's son, Mark.

Daniel Kerrigan died over the weekend following a violent struggle with Mark Kerrigan. The 45-year-old Mark Kerrigan has pleaded not guilty to assault and authorities are awaiting tests on the cause of his father's death.

Mark Kerrigan, who has a history of domestic violence arrests and was previously sued by his parents to recover money they spent for taking care of his home while he was in jail, is being held on $10,000 bail, and was noticeably absent from the funeral.

Family members said the death was unrelated to their argument early Sunday. Daniel Kerrigan's wife, Brenda Kerrigan, told the Boston Herald newspaper her husband died of a heart attack and there was nothing suspicious about his death.

But former prosecutor Wendy Murphy told CBS News actions speak louder than words. "Certainly, his family could have made the bail for him if they wanted him to be (at the funeral)," Murphy said.

Still, says Murphy, "Just because the heart attack followed the assault doesn't mean Mark Kerrigan caused his father's death."

Janet Kerrigan, who divorced Mark in 2007, tells "Inside Edition" her ex-husband once "strangled me in the bedroom." She says his "rage was beyond controllable."

She tells "Inside Edition" some of he ex's problems may have stemmed from jealousy.

"He would just say, 'Oh, it's always Nancy. Nancy.' That's what he would say. ... The focus was always on her. And that's when he felt very insecure. He would drink."

Mark Kerrigan is currently undergoing a mental health evaluation, reports CBS News Correspondent Whit Johnson.

Nancy Kerrigan didn't speak during the funeral Mass. She buried her face on her mother's shoulder and appeared to weep as her father's flag-draped casket was carried into the church.

In a statement, the former Olympian called her father "my support." He is the person who rushed to her and carried her into a locker room after an assailant clubbed her right knee during practice at the U.S. Championships in 1994.

"He was there behind me always," she said in the statement.
