This isn't a surpised to me either, I've been hearing this kinds of "evil" over the news since I was young. It's just unfortunate that the ones that are in the position to help the needy are the ones that were abusing the authority or power that they have.
I just hope that justice will prevail for the victims (2 girls or boys), it doesn't matter, the abuse is still an abuse.
I just saw the news last night about a girl-child rape & killed that happened in Surat city in India. I was so devastated by it and made me furious about it.
It must be stopped by all means.
