Surviving Idaho roommate thought noises of the killer were partiers

A survivor of the University of Idaho killings allegedly believed the sounds of four of her housemates being brutally murdered were sounds from college partiers in her house. Dylan Mortensen (pictured left), 21, allegedly called out to her friends and roommates during the early morning hours of November 13 to quiet down. 'Calm down, you're being loud!' she reportedly yelled around 4am, in addition to 'I'm trying to sleep!'
