That she worked in a pub has little bearing on whether she would know drug "users". Again, you're not specifying the "drugs" you are suspecting here. Most people in and out of pubs will know someone who smokes weed for example. Moreover, there is a bit of an ignorant inclination to think that anybody with a nose ring or who self describes as a "punk" might be into "drugs" or something nefarious... and somehow need their reputation protected by friends and family? This typecasting is actually quite offensive. Also, in the absence of evidence to the contrary, it's very unfair to speculate that her friends and family aren't being 100% honest and compliant with the police, or are overly concerned with her reputation in light of her death, to the point that it might impede an investigation. I think one needs to have some kind of evidence before casting an aspersion of suspicion over people who are entirely innocent, particularly now someone has been charged, as well as risking the reputation of the deceased by suggesting they were using unspecified "drugs". There is insightful speculation and ignorant speculation!
The idea that she would go to Finsbury Park to buy drugs is just complete rubbish, can we please rub that one out. Again:
1) young people can get most recreational drugs through friends, they don't need to risk going alone at night to unlit parks.
2) She didn't change her route home. She got knifed on the route home that she usually took with one of her former flatmates. The park is open after dark.
3) Just because she was into rock music and worked in a Camden pub, does not mean she was more or less likely to know any drug users who might have killed her in Finsbury Park or anywhere else...
I think it is a fair statement to say that Camden per head, visitors to that particular pub, and people who are associated with certain types of music might have a little higher percentage of drug users. That is why I thought it unlikely that Iuliana would need, even if she did use "recreational drugs", to venture into that area. And one of her friends, Krystyna in a previous post said that she had only just used the park as a short-cut and others said she often used it. So whenever there are differing answers amongst a victim's close circle, you may want to clarify why. As I did state earlier her occupation was much more of a red flag to me because women who work in public places are often subject to unwanted male attention.
And cannabis is a drug, and as someone who worked with young adults in psychiatric hospitals who suffered the onset of schizophrenia after becoming cannabis users, I do see it as potentially harmful, although it may be clinically useful in other conditions. There is significant research on cannabis and mental health, but many cannabis users want to perpetuate the untruth for whatever reason that it is a completely harmless drug. It is not.
And I also worked with drug addicts and alcoholics in rehab for six years and am well aware, thank you, that they come in all shapes and sizes and walks of life. That is why I believe that they deserve the same attention from the police if not more when they go missing as they are much more vulnerable. I even have friends who have piercings and tattos and sometimes use drugs believe it or not! As mature people I respect their choices as they respect mine. If one of them were to go missing/found dead, God forbid, I would give all details to the police of their lifestyle as potentially it may help them find them, or find their attacker, as I hope they would do for me. That is the only reason it is relevant. If as commented in the recent article, her friends say that police were slow to look for her, perhaps due to her youth, appearance or occupation then that needs to be challenged. They certainly should have been spared the awful experience of finding her.
I notice you talk about vagrants with "crazed eyes stalking you" as you cycled by and you thought "they might be the killer" and you don't think homeless people should be allowed to sleep in the park. You also speculate in your post 43 that Iuliana died as a victim of an "opportunistic killing by a vagrant" in an area notorious for being home to people down on their luck. I believe that homeless people are far more likely to be the victims of crime than the perpetrators. So you are making very definite assumptions about "vagrants". I find that equally offensive. And if mentally ill people (whom you also mention) are out there without supervision and support in the park or local community then that is the fault of the professionals who are supposed to be taking care of them, not their fault. If anyone sees someone in their local area who appears to be mentally ill they should report it so they can receive assistance.
There is a relevant question here as to how this area and others like it could be made safer so that the risk of the tragedy of Iuliana's death being repeated could be reduced. Is it ok to have "no go areas" that locals and older people may know to avoid but that young people, non-locals, vulnerable people, lower-paid people (particularly women) who are more likely to be on foot/using public transport, may not know about or have to pass through? Why are the police not patrolling that area, why is there no CCTV, proper lighting? Are resources to protect the public being properly distributed?
And when we do know about the circumstances/background/health of the murderer what might have been done to prevent him becoming such a danger to the public? And how are we going to prevent him being released back into society to attack again, which we see so often in our society? That is the only thing we can do now for Iuliana, is to make practical considered changes so that her death is not just brushed aside and things just carry on as if it didn't matter.
