Plummer said that during the early hours on May 16, 2013, Cosby, who had been drinking for 10 hours, was in his hotel room with Harris. At some point, when Cosby was asleep on a bed, the defense counsel said, "She woke him up saying, 'You need to pay me.'"
Cosby then told her to get out of the room, Plummer said, adding that an argument ensued during which Harris produced a lipstick-like knife with a razor-type blade on it.
"She cuts him right here, slashes across his arm," Plummer said, as Cosby was ushering her to the door. "When that knife slid across his arm, he reacted," Plummer said. Harris then stabbed Cosby in the temple with the knife, the defense counsel said.
