However, the crazed killer survives.

Police and emergency services arrived but Natchareeya was pronounced dead at the scene. The boyfriend was taken to hospital after the bullet exited through his cheek.

Natchareeya's shaken friend, who is seen with her in the CCTV, said the couple had separated and Natchareeya did not want to keep in touch.

She said: 'They had known each other for four or five years but recently started to argue. Natchareeya broke up with him. She wanted to finish.

'We came out of the dorm this morning and Natchareeya was angry to see him. She did not want to talk to him. She just wanted to get to class.
