The man scheduled to go on trial for the murder of Mollie Tibbets is asking that his confession be thrown out.

Attorneys for Cristhian  Rivera say he wasn’t properly read his Miranda rights and want his confession to be thrown out. He’s charged with first-degree murder in last year’s death of the Brooklyn native.

Attorneys for Rivera say he was not properly advised of his rights before his interview with police and also argue that Rivera should have been read his rights in his native Spanish, not in English.  Attorneys also say that Rivera admitted to being sleep-deprived before the interview and police shouldn’t have conducted the interview.

A hearing on the Motion to Suppress is scheduled for August 23rd in Woodbury County where the trial has been moved.
