Korean ex-JW brothers contacted the police and hinted to them that this murder could be related with WT's evil policy of shunning because
- Father was an elder (ministerial overseer)
- Mother was a regular pioneer
- Son was a ministerial servant focusing on Chinese speaking territory
- Killed daughter was an inactive JW
I can't be sure that her inactivity triggered family shunning and that shunning was the cause of that day's quarreling which ended as a murder, but I believe the police should consider alleged probability. All they said can be just faking an alibi. We all know the 21st century's JW is not such a religion believing in VooDoo things.

I'm waiting for results of the police and prosecutor's investigation.
