He knew that immersing himself in the case reports would shut out the guilt.

The autopsy report contained no surprises. The cause of death was as McCaleb had guessed from the video: cerebral hypoxia due to compression of the carotid arteries by ligature strangulation. The time of death was estimated to have been between midnight and three A.M. on January 1.
The deputy medical examiner who conducted the autopsy noted that interior damage to the neck was minimal. Neither the hyoid bone nor the thyroid cartilage was broken. This aspect, coupled with multiple ligature furrows on the skin, led the examiner to conclude that Gunn suffocated slowly while desperately struggling to keep his feet behind his torso so that the wire noose was not pulled tight around his neck. The autopsy summation suggested that the victim could have struggled in this position for as long as two hours.
McCaleb thought about this and wondered if the killer had been there in the apartment the whole time, watching the dying man struggle. Or had he set the ligature and left before his victim was dead, possibly to set some kind of alibi scheme into motion – perhaps appearing at a New Year’s Eve party so that there would be multiple witnesses able to account for him at the time of the victim’s death.
He then remembered the bucket and decided that the killer had stayed. The covering of the victim’s face was a frequent occurrence in sexually motivated and rage killings, the attacker covering his victim’s face as a means of dehumanizing the victim and avoiding eye contact. McCaleb had worked dozens of cases where he had noted this phenomenon, women who had been raped and murdered with nightgowns or pillowcases covering their faces, children with their heads wrapped in towels. He could write a list of examples that would fill the entire notebook. Instead he wrote one line on the page under Bosch’s name.
UNSUB was there the whole time. He watched.
The unknown subject, McCaleb thought. So we meet again.

Before moving on, McCaleb looked through the autopsy report for two other pieces of information. First was the head wound. He found a description of the wound in the examiner’s comments. The perimortem laceration was circular and superficial. Its damage was minimal and it was possibly a defensive wound.
McCaleb dismissed the possibility of it being a defensive wound. The only blood on the rug at the crime scene was that spilled from the bucket after it was placed over the victim’s head. Plus, the flow of blood from the wound at the point of the crown was forward and over the victim’s face. This indicated the head was bowed forward. McCaleb took all of this to mean that Gunn was already bound and on the floor when the blow had been struck to his head and then the bucket placed over it. His instinct told him this might have been a blow delivered with the intention of hurrying the victim’s demise; an impact to the head that would weaken the victim and shorten his struggle against the ligature.
He wrote these thoughts down in the notebook and then went back into the autopsy report. He located the findings on the examination of the anus and penis. Swabs indicated no sexual activity had occurred in the time prior to death. McCaleb wrote down No Sex in the notebook. Beneath this he wrote the word Rage and circled it.
McCaleb realized that many, if not all, of the suspicions and conclusions he was coming up with had probably already been reached by Jaye Winston. But this had always been his routine in analyzing murder scenes. He made his own judgments first, then looked to see how they stacked up next to the primary investigator’s conclusions afterward.
After the autopsy he went to the evidence analysis reports. He first looked at the recovered evidence list and noticed that the plastic owl he had seen on the videotape had not been bagged and tagged. He felt sure that it should have been and made a note of it. Also missing from the
