After School Massacre (2014) Timeline Explained – Every Event in Order

Devon and Jess had crushes on their teacher Ty Anderson and persuaded him to accept their Facebook friend requests. However, they then falsely reported to Principal Wheatley that Anderson had made sexual comments to them on Facebook, leading to his firing. Their motivation appears to be either revenge for rejecting them or manipulation, though the exact reason is left ambiguous.

Foreshadowing: Earlier scenes show the girls enthusiastically messaging Anderson online, establishing their obsession with him before the betrayal.

After killing Luke with a fireplace poker, Anderson placed his own mask into Luke's lifeless hand and fled the scene. When police arrived, they found Luke holding the mask and incorrectly assumed he was the killer, allowing Anderson to escape while an innocent man took the blame.

Foreshadowing: Earlier, Luke's violent attempted assault on Erin and his confrontational behavior with the group make him an easy scapegoat.

Luke, Dee Dee's boyfriend, attempted to force himself on Erin in Jess's bedroom while the party was underway. This subplot highlights the danger the girls face not just from Anderson but also from someone they know, adding another layer of threat to the night.

Anderson arrived at the party while most of the activity was happening inside. He ambushed Dee Dee outside when she went to buy more beer, killing her with a mailbox. This suggests he entered through a back or side entrance while the partygoers were distracted inside.

The victims were unaware that a killer was in the house. Anderson struck quietly and methodically, often when characters were alone or in isolated parts of the house. By the time the survivors realized what was happening, most of them were already dead or incapacitated, leaving no opportunity to call for help.

Foreshadowing: The party games and spy activities distract the group, while Anderson's hidden presence prevents early detection.
