There were defence wounds on both the upper and lower arms, as well as a number of small cuts to the hands, which suggested that she had struggled with her killer for the knife. There were also a significant number of other signs of trauma to the body, bruises and contusions, mostly on the arms and upper torso, some recent, others older. Forensic examination of the knife found in Zoukas's possession found that it matched in most particulars the weapon used in the attack. Further, there were three sets of fingerprints on the handle of the knife, Viktor Zoukas, Nina Simic and the smudged finger- and thumbprint of a third person, as yet unidentified. Zoukas himself was questioned again and again. All of the evidence so far could be made to support his story: a struggle between Nina Simic and an unknown assailant in which he had unsuccessfully attempted to intervene. Though inconclusive, medical evidence seemed to support his assertion that he had suffered a blow to the head which could have rendered him unconscious briefly.
