Blood Lust: Portrait of a Serial Sex Killer by Gary C. King

her throat,
where the neck joins the upper chest.
    After Jenny's body was opened with the usual
Y-shaped incision, Dr. Gunson determined that a major artery on the
left side of her chest had been severed and was the likely cause of
death. A V-shaped wound on her back had pierced the liver, and Dr.
Gunson explained that the V shape of the wound was probably the
result of two stab wounds that had overlapped.
    Dr. Gunson also pointed out other wounds,
including two quarter-inch-wide bruises around both of Jenny's
wrists. She explained that the bruises were an indication that the
victim had been tied up, perhaps with the shoe laces found at the
crime scene, and that significant pressure would have to have been
applied for such bruising to occur.
    Fingerprints and palm prints were obtained
from their well-developed Jane Doe, as were samples of blood,
urine, and head and pubic hair strands. Oral, anal, and vaginal
swab specimens were also collected and would later be tested with
acid phosphatase for the presence of semen. Each of the samples,
along with the paper bags that had enclosed Jenny's hands, were
retained by criminologist Gilliland.
    When Gilliland left the morgue, he went
straight to the Portland Police Bureau's Identification Division in
the towering downtown Justice Center building, carrying the
victim's fingerprints. After he was properly checked in, the prints
were classified and the search through the fingerprint files, often
a lengthy process, commenced. As luck would have it, however, the
search didn't take long this time. His Jane Doe was soon identified
as Jennifer Lisa Smith, also known as Gypsy Roselyn Costello, date
of birth November 14, 1961, making her twenty-five at the time of
her death. According to her rap sheet, she was a prostitute.
    While Gilliland had been making the
identification of their homicide victim in downtown Portland,
Turner was in Oregon City at the Clackamas County District
Attorney's Office, located in the courthouse, putting together an
affidavit of probable cause for issuance of a search warrant. The
effort took him the remainder of the afternoon.
    At 5:35 P.M., Turner presented the affidavit
before Clackamas County Circuit Court Judge Patrick Gilroy, inside
the judge's chambers. Gilroy read over the document, then promptly
issued warrants to search Dayton Leroy Rogers's home, his place of
business, pickup truck, and his person. The search warrants were
served that evening, making it a long day for everyone
involved.
    Among the items subsequently seized as
evidence were the bandage wrappers, a hacksaw, and blood samples,
all from Dayton's shop. From his home, the detectives took a pair
of Texas brand boots from the rear bedroom closet; a pair of Levi's
from the left side of his bed's headboard; a knife from a knife
block in the kitchen; two knives from a bowl on the kitchen
counter; and a box of Band-Aids from a cabinet near the kitchen
stove.
    While Turner was executing the search
warrants, first at Dayton's mobile home in Canby and then at his
shop in Woodburn, and preparing to have Dayton's truck removed for
searching, Detective Michael Machado read the warrant to search
Dayton's person. Present at the procedure was Dayton; Machado;
Dayton's attorney, Arthur Knauss; Deputy Larry Peck; and
Corrections Corporal Mike Baumgartner. Two vials of blood were
collected from Dayton, as were strands of his head and pubic
hairs.
    Dayton's pickup truck believed to contain
perhaps the most damning evidence associated with Jenny Smith's
death, was removed from his shop and taken to a secure garage on
the premises of the sheriff's office. Criminologist Robert Thompson
of the Oregon State Police Crime lab, accompanied by Turner and
Gilliland, went over the pickup later with much care and in great
detail.
    During its processing, they lifted latent
fingerprints from the pickup's right door and from the rear cargo
area's top rail section of the bed. A black piece of weather strip
