http://www.mercurynews.com/breaking-news/ci_29829842/san-jose-brothers-murder-charges-parents-anime The two boys told the cops some stranger killed their parents. They were off having fun and for days, the cops could not find them. A heck of a day for their parents. The boy that killed them scrawled on the wall of the garage that he was sorry for his clumsy first time killing. Now the reports are the family is Muslims.
I didn't see anything in there about an honor killing. Is there another link that ties the murder to their religion?
