Jodi Arias wrapped up her marathon eight-day testimony Wednesday, saying she had a “memory gap” the night she allegedly stabbed and fatally shot her ex-boyfriend Travis Alexander. Arias claimed she remembered getting in a fight with Alexander the night he died, possibly shooting him during the argument, putting the knife in the dishwasher, and disposing of the gun in the desert. But when asked directly, she said she only remembered the knife clinking onto the floor, but she had “no memory” of stabbing him 27 times. She also testified that she remembered pointing Alexander’s gun at him to protect herself, although authorities said there is no evidence that Alexander even owned a gun. Arias has been charged with Travis’s murder, and she could face the death penalty if convicted.
