| Quotes from testimony #2 | Victim described that “He had tattoos all over him” and she tried to memorize them. His left arm had one with “a woman’s face with long, flowing hair, and big, pretty eyes.” She helped prepare a composite of the tattoo. “Q. And as you described and as you remembered that tattoo, the description you gave to the police officers of it being on the left shoulder, you were mistaken? A. Yes.” Officer described defendant’s tattoo as “more on the back” than what she described, and he initially “chose not to show the lineup” since he was sure this was not the attacker based on her description, “[i]t appears to be a different tattoo,” and he did not want to “contaminate the witness.” Victim did not notice large tattoo that said “Wallis” Victim agreed that defendant’s appearance also looked “somewhat different” from that she had described; his hair was darker, he had more of a beard. |
