A former schoolmate of slain Iowa college student Mollie 
Tibbetts bore the child of the man accused of killing her, 
according to a report.

Iris Monarrez was a cheerleader at Brooklyn, Guernsey, and 
Malcom High School while Tibbetts was on the track team there, a 
picture in their yearbook obtained by the Daily Mail shows.

While in school, Monarrez, now 25, dated Cristhian Rivera, 24, 
who is accused of abducting and killing Tibbetts.
