HAMILTON, Ohio - Khrendon Gray, 19, said under oath yesterday that he thought a friend had been stabbed during a fight the night Amber Robinson was killed.

 Gray said he was surrounded by a "swarm" of people and that "I started swinging for my life - there were too many of them." It was during this fight that the Lakota West High school student was killed.

According Gray it was the second fight of the night. Robinson and another girl had gotten in a fight earlier that was broken up by police.

Butler County Judge Keith Spaeth had Gray's mother removed from the courtroom for yelling out that her son is bipolar and needs medication.

Testimony from the a coroner's office forensic pathologist said Robinson was stabbed twice and that the wounds were inflicted by someone coming from behind--not from rapid flailing as the defendant claims.

The jury is set to begin deliberations today, March 11.
