text: Drive-by death: Cassandra Cassidy was fatally wounded as she tried to help two women 'afraid of men in a car' outside a rehab centre . A 24-year-old rehab worker killed in a drive-by shooting in Las Vegas was an 'innocent bystander' who had been trying to aid two women who had approached her in the street. Cassandra Cassidy had been stopped outside the addiction recovery centre where she worked shortly after 10pm on Friday by two females 'afraid of males in a car', police have said. The fashion design student was shot as a car occupied by multiple people drove past while she was talking to the women, and died in hospital shortly afterwards. Ms Cassidy had just arrived for her late-night shift at a half-way house for people struggling with substance abuse, when the women approached her, Las Vegas police said in a statement. The women later told police they had been afraid of two men in a car down the street and asked to use Ms Cassidy's phone to call for help. A white, two door car with several occupants drove up to Ms Cassidy's car and fired several rounds, striking Cassidy but not the two women, before it sped off, Lt. Jeff Goodwin of Las Vegas Metropolitan Police said. The aspiring designer, who had recently launched her own vegan clothing label, was mortally wounded and taken to University Medical Center where she died. The death of Ms Cassidy, who described herself as 'a 24-year-old fashion design student,  artist, geek, photography enthusiast, hiatus model, and many other things' on her Instagram page, has devastated family and friends. Her boyfriend of two years, Adam Loghides, 26, said working at the rehab centre was a perfect fit for her, as she 'always finds the best ways and finds the best qualities in people'. The International Academy of Design & Technology-Las Vegas's student, was 'an avid supporter of civil rights and LGBTQ issues and someone who represented fairness on all levels and equality,' Mr Loghides told the Las Vegas Review-Journal. Las Vegas Metropolitan Police are investigating the shooting but have yet to make any arrests.
