Julie was on the 57 tram route, that goes up Elizabeth St, round Errol St, and down Abbotsford st. in those days it went past Canning St, and across Flemington up to the Zoo ( nowadays the Toorak tram does that ) different starting point and different line, but certainly doable.... the trams ran right up until about 2am in those days, I think they still do...
Still,. ..he has to get home, after killing Julie, .. same as getting home after the Easy St horror....
Like that young bloke who killed that lovely Palestinian student, on the Bundoora tram line, last stop, I think, and the last tram so police figured out, correctly, that he lived at that last tram stop, or close to it...
