:: January 15: Rodger calls police and accuses a room-mate of stealing three candles worth 22 dollars. Rodger has made a citizen's arrest on him for petty theft. His room-mate is booked into jail and later cited and released. The case is referred to the district attorney who files a petty theft charge.

:: April 24: Rodger wakes up with a cold, thwarting his original plans to carry out the killings on April 26, according to the manifesto. It says his father has arrived home earlier than expected and he is not "mentally prepared" to kill him too. He sets a new date of May 24 for the massacre.

:: April 26: Rodger writes that he has avoided the Isla Vista area, not wanting to to hear his "enemies" partying and having a good time on the day he had planned to kill them.
