You guys aren't reading these stuff deeply enough.
"The satellite firm that employed Alps murder victim Saad Al-Hilli may have been targeted by Iranian intelligence agents desperate to get their hands on high-resolution images of their enemies’ defence and weapons sites." Because he was some kind of genius scientist and so he went to the police, and they posted 24/7 surveillance on the family, but when they went to the French Alps to have a vacation, the surveillance did not go with them.
The family were shot all in the head, except for one daughter who hid inside her Mother's skirts. A cyclist was shot dead after he passed by and witnessed the shooting. He was shot in the head by the hired killer.
That is the story.
