murder book and the small archival evidence box from the 1989 case.
    “Okay,” Bosch said, when everyone was seated. “So you are cool with us running with this case? If you’re not, we can go back to the lieutenant and say you really want to work it.”
    “No, it’s okay,” Shuler said. “We both are involved in the trial, so it’s better this way. It’s our first case in the unit and we want to see it through to that guilty verdict.”
    Bosch nodded as he casually opened the murder book.
    “You want to give us the rundown on this one, then?”
    Shuler gave Dolan a nod and she began to summarize the 1989 case as Bosch flipped through the pages of the binder.
    “We have a nineteen-year-old victim named Lilly Price. She was snatched off the street while walking home from the beach in Venice on a Sunday afternoon. At the time, they narrowed the grab point down to the vicinity of Speedway and Voyage. Price lived on Voyage with three roommates. One was with her on the beach and two were in the apartment. She disappeared between those two points. She said she was going back to use the bathroom and she never made it.”
    “She left her towel and a Walkman on the beach,” Shuler said. “Sunscreen. So it was clear she was intending to come back. She never did.”
    “Her body was found the next morning on the rocks down at the cut,” Dolan said. “She was naked and had been raped and strangled. Her clothes were never found. The ligature was removed.”
    Bosch flipped through several plastic pages containing faded Polaroid shots of the crime scene. Looking at the victim, he couldn’t help but think of his own daughter, who at fifteen had a full life in front of her. There had been a time when looking at photos like this fueled him, gave him the fire he needed to be relentless. But since Maddie had come to live with him, it was increasingly more difficult for him to look at victims.
    It didn’t stop him from building the fire, however.
    “Where did the DNA come from?” he asked. “Semen?”
    “No, the killer used a condom or didn’t ejaculate,” Dolan said. “No semen.”
    “It came from a small smear of blood,” Shuler said. “It was found on her neck, right below the right ear. She had no wounds in that area. It was assumed that it had come from the killer, that he had been cut or maybe was already bleeding. It was just a drop. A smear, really. She was strangled with a ligature. If she was strangled from behind then his hand could have been against her neck there. If there was a cut on his hand…”
    “Transfer deposit,” Chu said.
    “Exactly.”
    Bosch found the Polaroid that showed the victim’s neck and the smear of blood. The photo was washed out by time and he could barely see the blood. A ruler had been placed on the girl’s neck so that the blood smear could be measured in the photo. It was less than an inch long.
    “So this blood was collected and stored,” he said, a statement meant to draw further explanation.
    “Yes,” Shuler said. “Because it was a smear it was swabbed. Back then, they typed it. O-positive. The swab was stored in a tube and we found it still in Property when we pulled the case. The blood had turned to powder.”
    He tapped the top of the archive box with a pen.
    Bosch’s phone started to vibrate in his pocket. Normally, he would let the call go to message, but his daughter was home sick from school and alone. He needed to make sure she wasn’t calling. He pulled the phone out of his pocket and glanced at the screen. It wasn’t his daughter. It was a former partner, Kizmin Rider, now a lieutenant assigned to the OCP—Office of the Chief of Police. He decided he would return her call after the meeting. They had lunch together about once a month and he assumed she was free today, or calling because she’d heard about him getting approved for another four years on the DROP. He shoved the phone back into his pocket.
    “Did you open the tube?” he asked.
    “Of course not,” Shuler said.
    “Okay, so four months ago you sent the tube containing the swab and what was left of the blood out to the regional lab, right?” he asked.
    “That’s right,” Shuler said.
    Bosch flipped through the murder book to the autopsy report. He was acting like he was more interested in what he was seeing than what he was saying.
    “And at that time, did you submit anything else to the lab?”
    “From the Price case?” Dolan asked. “No, that was the only biological
