Maybe it is not an honour killing maybe it is just a "normal" killing of a girlIt sounds much more like "typical" neglect and violence that led to a death rather than anything more "special".
And as for someone hiding them, yeah probably family or friends, the same as has happened so many times in the UK with our native criminals who've killed someone, but with the added difficulty that our police have no jurisdiction in Pakistan and it's going to be entirely reliant on our government putting pressure on the Pakistan government to find and extradite the suspects, with our police making enough of a case to persuade a Pakistani court that it satisfies their own laws in regards to any extradition treaty we have with them.
An honour killing on a 10 year old?
