procedure to eliminate a pregnancy. The deputy coroner who conducted the autopsy estimated that this had occurred four to six weeks prior to her death.
Bosch read the first Investigator’s Summary report, which was written and added to the book after the autopsy. Green and Garcia had now classified the death as a murder and established the theory that someone had entered the girl’s bedroom while she was sleeping, incapacitated her with a stun gun and then carried her from the room and the house. She was carried up the mountainside to the location by the fallen oak tree, where the murder was committed and clumsily disguised as a suicide in what was possibly a spur-of-the-moment decision by her killer. The report was filed Monday, July 11-five days after Rebecca Verloren had been left dead on the hillside.
Bosch moved on to the firearm analysis report. Though the autopsy had produced more than convincing evidence of staged suicide, the study of the gun and the attendant ballistics further confirmed the investigative theory.
The gun was found to be devoid of fingerprints except for those from Becky Verloren’s right hand. The fact that there were no prints from her left hand or smudges of any kind on the pistol indicated to the investigators that the weapon had been carefully wiped clean of prints before being placed and held in Becky’s hand, then turned toward her chest and fired. It was likely that the victim was unconscious-from the stun gun assault-at the time this manipulation occurred.
The bullet casing ejected from the pistol when the fatal shot was fired was recovered six feet from the body. There were no fingerprints or smudges on it, an indication that the weapon had been loaded with gloved hands.
The investigation’s single most important piece of evidence was recovered during the analysis of the gun itself. It was actually found inside the gun. The weapon was the Mark IV Series 80 model manufactured by Colt in 1986, two years before the murder. It featured a long hammer spur, which was notable because the gun had a reputation for leaving a “tattoo” injury on the shooter if the weapon was not handled properly while firing. This usually occurred when a two-handed grip on the weapon pushed the primary shooting hand up high on the grip and too close to the hammer spur. The primary hand could then receive a painful stamp when the trigger was pulled, the weapon fired and the slide automatically came backward to eject the bullet casing. As the slide returned to firing position, it would pinch the skin of the shooter’s hand-usually the webbing between the thumb and forefinger, often taking a piece of skin back with it inside the gun. All of this occurred in a fraction of a second, the novice shooter often not even knowing what had “bitten” him.
That was exactly what had happened with the gun used to kill Becky Verloren. When a firearms expert broke open the weapon he found a small piece of skin tissue and dried blood on the underside of the slide. It would not have been noticeable to someone examining the exterior of the gun or wiping it clean of blood and fingerprints.
Green and Garcia added this to their investigative theory. In the second Investigator’s Summary report they wrote that evidence indicated that the killer wrapped Becky Verloren’s hand around the gun and then pressed the muzzle to her chest. The killer used one or both of his own hands to steady the weapon and push or pull her finger over the trigger. The gun fired and the slide “tattooed” the killer, taking a piece of his skin with it inside the gun.
Bosch noted to himself that Green and Garcia made no mention of another possibility in their investigative theory. That being that the tissue and the blood found inside the weapon was already there on the night of the murder, that the weapon had tattooed someone other than the killer when it was fired at some point before the killing.
Regardless of that potential oversight, the blood and tissue was collected from the weapon and, while it was already known from the autopsy that Becky Verloren had no wounds on her hands, a routine blood comparison test was conducted. The blood collected from the gun was type O. Becky Verloren’s blood was type AB positive. The investigators concluded they had the killer’s blood on the weapon. The killer was blood type O.
