Duale said that Otieno's murder has shocked the nation.
The MP also said that as Parliament they will push to have all unresolved murder cases reviewed.
He said that many families of unresolved murders are crying for justice.
Ms Otieno's body was discovered on Tuesday, two days after she was abducted.
