BRECKENRIDGE - Erik Rockne admitted Monday to violating one of the conditions of his probation relating to a series of charges stemming from his arrest in Jan. 2007.Police originally arrested Rockne, then 39, on suspicion of second-degree attempted murder, intimidating a victim, false imprisonment, false reporting to authorities and domestic violence - all related to a fight with his former girlfriend.Acknowledging that he could face revocation of his probation, as well as jail time and fines, Rockne told Judge Terry Ruckriegle Monday that he was drinking alcohol in September while traveling as a passenger in a car with the alleged victim, his former girllfriend.He now faces a Dec. 28 re-sentencing hearing on the violation.In June, 2008, the felony attempted murder charge was dropped and Rockne pleaded no contest to criminal mischief and third-degree assault. He agreed to undergo domestic violence classes and drug and alcohol treatment. The numerous other charges against him, including attempted manslaughter, intimidating a witness and first-degree assault, would be dropped. A sexual assault charge against Rockne was also dropped because there was no factual basis that an assault occurred, according to a previous story in the Summit Daily News.Rockne's family are prominent, longtime members of the Breckenridge community. His father helped found Breckenridge Ski Resort in the 1960s.The alleged victim claims Rockne received favorable treatment because of his family's wealth and social status.According to previous reports in the Summit Daily, the alleged victim's allegations against Rockne were undermined by her own 10-year criminal history in Summit County, including a string of alcohol- and drug-related charges.
