Suspects in two high-profile Iowa murder cases are both pleading not guilty. Wesley Correa-Carmenaty is charged with killing Pottawattamie County sheriff's deputy Mark Burbridge during a jailbreak in Council Bluffs earlier this month. He's requested a "speedy trial" but the county attorney says the trial date remains scheduled for July 25th. Meanwhile, the 21-year-old man charged with the shotgun deaths of his parents and sister in Bondurant last month is also pleading not guilty. Chase Nicholson entered a written plea Monday. He allegedly admitted to the killings.
