Mark Harmon, best known for his iconic role as Leroy Jethro Gibbs on the hit TV show NCIS, has faced his own share of legal controversies in real life. One of the most shocking incidents involved a custody battle with his sister, Kristin Nelson, in the 1980s. After divorcing rock star Ricky Nelson, Kristin struggled with drug and alcohol addiction, leading to a bitter court battle with Mark and his wife over the custody of her youngest son, Sam Nelson. Mark ultimately retained visitation rights over Sam, but the rift between the siblings remained. Kristin, who had a successful acting career in the ’60s and ’70s, including roles on The Adventures of Ozzie and Harriet, passed away from a sudden heart attack in 2018. Despite the family’s therapy sessions to repair their relationship, Mark has never publicly commented on his sister’s passing, leaving many questions unanswered.
