Trigger warnings for abuse, child abuse, violence, murder excetra, also possible victim blaming in comments on the article.
http://www.dailymail.co.uk/news/article-2100537/Man-beat-girlfriends-son-11-death-hours-refused-vacuum.html Basically a woman's 29 year old boyfriend battered her eleven year old son to death because the child allegedly refused to vacuum the apartment.
He beat the child so hard that all three of the wooden sticks he used all broke. Blood was found on the ceiling and covering a number of weapons including iron bars.
The victim's five year old brother witnessed this awful brutality.
I suggest not reading the comments, many of them blame the mother for it happening despite no evidence for that supposition.
