Mollie Tibbetts Was Facebook Friends With Her Accused Killer’s Girlfriend

Slain college student Mollie Tibbetts attended the same school as her accused killer's ex-girlfriend. The two girls were also Facebook friends, but in a small town like Brooklyn, Iowa, it's unclear if they were really friends. Iris Monarrez, who has a 3-year-old daughter with suspect Cristhian Rivera, lived in a red trailer on the farm where Rivera worked until they broke up last year. Monarrez was just one grade above Tibbetts at their high school and their graduating classes only had about 40 students each.
