Police and security staff were forced to intervene after emotional scenes erupted at the court appearance of Evie Butterworth — the woman accused of killing a 21-year-old while driving on a cocktail of drugs at 188km/h. Ms Butterworth is charged over the death of Abbey Sheriff — who died after the horrific crash in Baldivis in January. A throng of supporters — including Ms Sheriff’s parents Darren and Julie — wearing T-shirts showing a picture of Ms Sheriff were in attendance for the 29-year-old’s appearance at Stirling Gardens Magistrates Court on Wednesday morning. Ms Butterworth entered court via the usual entrance, with police watching closely. After having her case adjourned for eight weeks, Ms Butterworth’s lawyers flagged an application to have her 8pm to 7am curfew bail condition removed. Prosecutors opposed it and Magistrate Janet Whitbread declined to hear the application. When Ms Butterworth was released on bail, The West Australian understands that she was allowed to leave the courtroom via an exit enabling her to avoid confrontation with Ms Sheriff’s family and supporters. Ms Butterworth will reappear in court in April. During an earlier bail application, WA Police alleged that Ms Butterworth was travelling between 141km/h and 188km/h when she hit Ms Sheriff’s Nissan X-Trail at 11.35pm on January 11, just after the northbound Mundijong-Kulija Road on-ramp off Kwinana Freeway in Baldivis. Ms Sheriff had been on her way to comfort a distressed friend, driving a route she regularly took to her job at the Dome Cafe in Kwinana. The court was told that major crash investigators were able to calculate Ms Butterworth’s average speed after she was clocked at a Pinjarra service station about 11pm that night, about 47km from the scene of the accident. Police alleged that Ms Butterworth struck the right-hand side of Ms Sheriff’s X-Trail, forcing it to roll several times before eventually landing 120m from the area of impact. Ms Sheriff had catastrophic injuries and could not be saved, with St John WA paramedics declaring her dead at the scene. Police allege that a blood sample taken from Ms Butterworth showed that she had a cocktail of drugs in her system, including 0.25mg of methamphetamine, 0.8mg of amphetamine, 0.1mg of cocaine and 1g of tetrahydrocannabinol — the psychoactive substance found in cannabis. The court was told that a toxicology report also confirmed that Ms Butterworth was “incapable of controlling a motor vehicle” given the level of drugs in her system. A Facebook page, Justice for Abbey Sheriff, has been set up by her parents.
