A ninth Somali man has pleaded guilty to piracy for his role in the hijacking of a yacht that left four Americans - including two from Seattle - dead.
Ahmed Sala Ali Burale pleaded guilty in federal court in Norfolk on Wednesday. Muhidin Salad Omar also pleaded guilty earlier in the day.
They are among 14 people from Somalia and one from Yemen charged in connection with the February hijacking of the yacht Quest.
Yacht owners Jean and Scott Adam of Marina del Rey, Calif., and friends Bob Riggle and Phyllis Macay of Seattle, were shot to death after being taken hostage several hundred miles south of Oman.
Prosecutors don't believe any of the men who have pleaded guilty shot the hostages.
They each face life in prison, although that could be reduced.
