Amy Elizabeth Richins, a mother of three, was arrested last month on suspicion of poisoning her husband. At Monday's hearing, prosecutors and Richins' attorneys previewed evidence in the case, with Richins' sister-in-law calling her "desperate, greedy and extremely manipulative". Richins' attorney argued that the evidence was "very one-sided" and that Richins will be exonerated by a jury. The case has gained widespread attention due to the unique circumstances surrounding it.
