Jealousy was the reason for a Thai man, killing his ex girlfriend/wife and an innocent bystander in a parking garage.
You can see the man following his ex, a dispute starts. Then an innocent man tries to arbitrate the dispute, he is fatally shot in the head by the suspect. Finally, the suspect also executes the woman by shots to the head.

Very cool, 1 down, 9 more to go.
