How and when did David kill Mr. Peterson's boss?

How and when did David kill Mr. Peterson's boss? - Multicolored head sculptures of David near bright statuettes placed in store with abundance of souvenirs and black pillar with book

Mr. Peterson's boss is the only death in The Guest (2014) that wasn't shown on screen. I can't figure out how David could've fit this in his schedule:

  • Day 1: David meets everyone in Caleb's family. Dad told him about his boss.
  • Day 2: Picks up Luke, fights with the bullies, goes to the party
  • Day 3: Kills the gun dealer & friend, frames Anna's bf. Dad comes home and says his boss has been missing for a few days and was just found dead.

There's no way David could've killed the boss on day 1. If he somehow did kill him on the night on day 2, then the boss would've missed work only one day on day 3. Can someone please explain?
