This is the sickening moment a jilted boyfriend calmly executes his ex-girlfriend outside her university dorm - shooting her in the chest with a handgun.
Killer Pukkapong Chittarom, 24, sought out student Natchareeya Thaprajit, 21, near her home in Bangkok, Thailand, this morning.
The pair had known each other for about five years but had recently separated - with Natchareeya refusing to reconcile with him.
