SUNBURY -- The defense is seeking to have the murder weapon in the so-called Craigslist thrill kill thrown out.
Miranda and Elytte Barbour were both in court Tuesday for pretrial motions.
They're accused of killing Troy LaFerrara of Port Trevorton last November.
Miranda Barbour's attorneys say there were mistakes in search warrants.
If those warrants are thrown out, prosecutors will not be able to use the knife from the murder as evidence. No decision was made on that.
A judge decided that Elyette Barbour is competent to stand trial, meaning prosecutors in Northumberland County will be able to seek the death penalty.
