Proof of Innocence--> DNA Evidence

DNA tests conducted by the Commonwealth “eliminated” Joe, Derek, Danial, and Eric as contributors of any of the genetic material recovered from the crime scene.  Those same tests established conclusively that Ballard matched sperm recovered from Ms. Bosko and the blanket covering her.  Ballard also matched blood found under Ms. Bosko’s fingernails from where she had scratched him during the attack.


DNA Evidence Exonerates Danial, Joe, and Derek


DNA analysis conducted by the Commonwealth eliminated Danial, Joe, Derek, and the other sailor suspects as contributors of any of the blood or semen left by the killer.  After testing the sperm and blood stains on a white blanket that covered the victim’s body, blood stains on the comforter in the bedroom, swabs of the victim’s vaginal areas, clippings of the victim’s fingernails, and blood on the blade of the murder weapon, the Commonwealth reported
Based on the DNA profiles obtained, D. Williams, W. Bosko, J. Dick, E. Wilson, D. Tice, R. Pauley, G. Farris, R. Mattingly, J. Wagner, and J. Danser are each eliminated as a possible source of the foreign genetic material detected in these samples.  See February 18, 1999 Division of Forensic Science Certificate of Analysis.
These results confirmed once again that the sailors, including Danial, Joe, and Derek, were not the source of the genetic material recovered from Ms. Bosko’s apartment.

DNA Evidence Conclusively Establishes Ballard As the Sole Perpetrator


Ballard’s DNA is the only foreign DNA recovered from the crime scene


Days after DNA analysis eliminated each of the sailor suspects once again as a DNA match, Ballard surfaced as a suspect.  DNA testing conducted by the Commonwealth revealed that the DNA recovered from the crime scene conclusively tied Omar Ballard – and only Omar Ballard – to the crime.  The Commonwealth’s forensic scientist reported that the DNA profile of the blood obtained from Ms. Bosko’s left-hand fingernail clippings was consistent with a mixture of Ms. Bosko and Ballard.  The sperm retrieved from the victim’s vaginal swabs also was “consistent with a mixture of the DNA profiles of Ms. Bosko . . . and O. Ballard.” There was no other foreign DNA detected in the swabs.

Ballard’s DNA was found on a vaginal swab of the victim


The Commonwealth’s forensic scientist concluded that the sperm from the victim’s vaginal swab was:
23 million times more likely to have originated from O. Ballard than from an unknown individual in the Caucasian population;

20 million times more likely to have originated from O. Ballard than from an unknown individual in the Black population; [and]

51 million times more likely to have originated from O. Ballard than from an unknown individual in the Hispanic population.

Ballard’s DNA was found on a blanket next to the victim


Ballard’s DNA also matched the sperm and non-sperm fractions of the stains from the white blanket covering Ms. Bosko’s body.  Again, no DNA foreign to Ms. Bosko and Ballard was detected, and the factor of certainty was even more compelling.  The Commonwealth’s forensic scientist concluded that the sperm and non-sperm material recovered from the stains on the white blanket was:
21 billion times more likely to have originated from O. Ballard than from an unknown individual in the Caucasian population;

4.6 billion times more likely to have originated from O. Ballard than from an unknown individual in the Black population; [and]

87 billion times more likely to have originated from O. Ballard than from an unknown individual in the Hispanic population.  See May 6, 1999 Division of Forensic Science Certificate of Analysis.
