Two years ago, in 2011, authorities confirmed for the first time the bones belonged to John Sohus, using DNA provided by his sister, Lori Moltz. The premature technology of DNA testing back in the 1990s and the fact Sohus was adopted as a child delayed the definitive identity of the remains.
By 1993, Gerhartsreiter -- posing as Rockefeller -- met Sandra Boss. The couple married in 1995 and their daughter, Reigh, was born in 2001.
Boss testified last week that after their daughter was born, her husband became "an unpleasant human being who was choosing not to work" and a constant liar. As the family breadwinner, Boss said she was earning $1.2 million a year at a management consulting firm in New York and her bank account and the family finances were controlled by her husband.
In January 2007, Boss filed for divorce. It was during the divorce proceedings that Boss said Gerhartsreiter's true identity began to unravel, according to court documents. When the divorce was finalized in December 2007, Boss and her daughter moved to London and Gerhartsreiter was granted supervised visitation rights.
In September 2008, Gerhartsreiter was arrested and charged with kidnapping their then-7-year-old daughter and assaulting a social worker with a dangerous weapon during a supervised visitation in Boston.
He was convicted and sentenced to five years in a Massachusetts state prison the following year.
