OMAHA — Douglas County investigators are looking into a new tip about they hope can lead them to the remains of a missing University of Nebraska at Omaha student.

Jessica O’Grady, who is presumed dead, was last seen alive on May 10, 2006. She made a call from her cell phone late that night, saying she was going to the house of a man she had dated, Christopher Edwards. Edwards is now serving 80 years to life for the 19-year-old woman’s death, although her body has never been found.

Investigators aren’t giving any details of the tip, but say it is promising.

Authorities say a $10,000 reward is still being offered for information that leads to the discovery of O’Grady’s remains.
