Speculation surfaced Monday night around a Facebook post associated with the same name and as the ones that appear on Minassian’s LinkedIn profile. CBC News has not been able to independently verify whether the Facebook post was, indeed, written by Minassian or created after that fact and intended to mislead.

The post referred to the “Supreme Gentleman Elliot Rodger.” Rodger was the 22-year-old California man responsible for a deadly rampage in Isla Vista, Calif., that left six people dead and a dozen more injured.

In a video posted ahead of that 2014 attack, Rodger raged about a number of women turning down his advances, rendering men like him “incels,” a term used by some groups to mean “involuntarily celibate.”
