WOBURN -- Mark Kerrigan, the brother of skater Nancy Kerrigan, has had a turbulent history with his parents, who sued him for $105,000 in 2008, according to court records.
In court papers at the time, the parents said Mark Kerrigan, who is accused of assaulting his father over the weekend, owed them $105,000 they had spent taking care of his dogs, paying the mortgage on his Wilmington home, and for paying a lawyer who represented him on assault charges in 2006.
When the lawsuit was filed, Mark Kerrigan's address was listed as the Middlesex County House of Correction in Billerica, where was serving a sentence for a 2006 assault conviction, records show. He was released from county prison last Nov. 22.
