Lindt cafe victim Tori Johnson was shot dead in the final act of the Sydney siege, killed by Man Haron Monis as other hostages fled.
Hostages held at gunpoint in a Sydney cafe for more than 16 hours were told they would be "dead in the morning", prompting them to smash a lock off a door and run for their lives.
Sources have told 9NEWS Monis fired one shot from a sawn-off shotgun. Mr Johnson was shot in the head.
AAP reported the gunman screamed at police: "look what you've made me do".
Police are still trying to determine how fellow victim Katrina Dawson died, and are waiting for ballistic tests.
More than 70 police officers are being interviewed to determine the circumstances of the final stand.
The timeline was revealed as authorities came under increasing pressure to explain how Monis, a man with a long criminal history and links to extremism fell off watch lists and was granted bail.
