We can't believe this has to be said but stop going to Liam's house as well as his family's house. Just the fact that people have looked for the addresses is beyond disrespectful but actually going there is unbelievable.
Let his family mourn in peace and privacy. And being aware that his house is close to his son's and yet, still going there is disgusting. Imagine the poor little boy seeing this?
Please be respectful, if you need to say goodbye, go to a fan-made memorial. But leave his and his relative's houses alone. STOP going there.
