POWASHIEK COUNTY, Iowa - A judge could decide, this week, if prosecutors can use an interview with the man accused of killing Mollie Tibbetts at his trial.
The defense for Cristhian Rivera claims officers didn't properly read him his Miranda Rights.
A judge originally scheduled the hearing for last month but it was later delayed.
Rivera's lawyers say officers violated his Miranda Rights in their initial interview with him last year, claiming officers didn't read the suspect his rights until well into the 12-hour interview.
They also say the officers didn't read them in their entirety.
A hearing is scheduled to start Wednesday morning at 9 a.m. at the Poweshiek County courthouse.
Rivera's trial is set to start on Feb. 4 in Woodbury County.
