An Oregon woman who came home and beat her boyfriend's former girlfriend with a crowbar after finding her getting high on heroin in her bathroom will no longer face prosecution. Elena Curtin of Portland was seven-months pregnant when she was charged with second-degree assault after she struck her boyfriend's ex in the head and arm with a crowbar in November 2014. She was set to go to trial in Multnomah County Circuit Court this week, but prosecutors dropped the charge on Monday because Curtin, 23, was 'completely justified in her outrage'. Elena Curtin of Portland, Oregon, was seven-months pregnant when she was charged with second-degree assault after she struck her boyfriend's ex in the head and arm with a crowbar in November 2014 . Curtin gave birth in January. When Curtin came home, she found her boyfriend's ex-girlfriend shooting heroin while sitting on her toilet, Oregonian/OregonLive reported. When she asked her to leave and the woman refused, Curtin beat her with a crowbar. Oregon law allows for use of physical force against an intruder who won't leave a resident's home. Curtin's defense attorney, Casey Kovacic, said the ex-girlfriend was 'jealous and bitter' that the boyfriend was in a relationship with his client. The boyfriend, who is the father of Curtin's child, struggled with heroin in the past. The ex and the boyfriend had gotten high at the apartment before and they have a five-year-old child. They have since reconciled and Curtin is now living with her parents. The boyfriend has not been a part of his new child's life. Kovacic wrote in an email: 'In the two years leading up to this incident, [the ex] made it her personal mission to make Elena's life miserable. 'She routinely harassed and threatened to hurt Elena, stole from her, and cruelly plotted to drag [the boyfriend] back into addiction. 'That's one silver lining -  she's [Curtin] been able to examine how bad (her relationship) was and move on with her life.' If she had gone to trial and been convicted, Curtin would have faced received a mandatory prison sentence of almost six years.
