Suspect in Mollie Tibbett’s case asks judge to approve sleep deprivation expert witness

POWESHIEK COUNTY, Iowa. (WHO) – A new motion was filed in the case of the man charged with Mollie Tibbett’s murder.

According to our NBC affiliate WHO-TV, attorneys for Cristhian Rivera filed a motion Wednesday requesting the court’s approval to appoint expert witnesses.

They’re also asking for the state to pay for hiring those experts, along with services already provided by a translator.

The motion filed asks for approval of Dr. Kimberly Fenn of Michigan State University. Fenn is an expert in the area of sleep deprivation and its effects on the actions and statements of the sleep-deprived, as an expert witness.

Rivera is charged with first-degree murder in the death of Tibbetts. She disappeared while jogging in her hometown of Brooklyn on July 18, 2018.

Tibbett’s body was found nearly a month later, after investigators say Rivera led them to a cornfield.
