Douglas County Attorney Stu Dornan has filed a Second-Degree Murder charge against 19-year-old Christopher Edwards. Prosecutors claim he killed Jessica O'Grady with a sword.

Edwards was arrested last week.

During a news conference Monday afternoon, Dornan said investigators believe that Ms. O'Grady was killed with a Bangkok battle sword, similar to those pictured on the right. It's a weapon that is 26 inches long with a 19 inch blade. Dornan says the death was intentional.

Nineteen-year-old Jessica O'Grady was last heard from on May 10th. Authorities say they are certain that she is dead but her body has never been found.

Edwards faces a bond hearing Tuesday and prosecutors say they ask that bond be denied.

Authorities say that Edwards was a boyfriend of O'Grady's and the house he lived in at the time of her disappearance has been searched twice during the course of the investigation. Several pieces of evidence were taken from the home near 130th and Cady.

Edwards surrendered to the sheriff on Friday afternoon, accompanied by attorney Matt Higgins who said his client is innocent.

Higgins said Friday, "he's confident in the system; he's confident in his lawyers and he's confident that he will be acquitted of this charge."

Jessica O'Grady's family members were at the Monday news conference as additional details of the case were unveiled but they said they would have no comment today.
