spent the next five hours going over the Port Melbourne apartment, where the murder of Jeremy Wilson and the battering of his wife Teresa took place. One of their neighbours had informed us of their identities.
We called the State Emergency Services (SES) to provide us with adequate lighting of the area, inside and out of the building.
Prior to collecting evidence, we proceeded with a preliminary examination, which entailed observation only. The last thing we needed was to risk contaminating the crime scene any more than we already had. Collection of evidence would be done after we’d made a thorough assessment of the crime scene.
The preliminary examination was a walk-through evaluation of the crime scene. This stage was one of the most critical phases of searching the crime scene for evidence. The impressions we gained from this walk-through were going to formulate how the scene would be processed.
During the walk-through, Frank and I kept our hands deep inside the pockets of our overalls, just to stop ourselves from touching anything.
We moved through the apartment by walking in areas which did not appear to contain any potential evidence. I took extra care when walking through the hallway, doorways or any areas where potential footprint or footwear impressions, fingerprints, and other trace evidence could have been left behind.
The only rooms which seemed to have been disturbed were the bedroom and the hallway. A small window in a room adjacent to the bathroom had been left ajar.
I made mental notes of any sign of forced entry, the location of potential items of evidence, and the presence or absence of blood in various areas of the scene.
Following the preliminary examination, we videotaped the entire area.
Since the introduction of the video camera nearly two decades ago, forensic investigators had additional means to accurately record information. This method of recording information at a crime scene was better than photography at times, because it gave us a three-dimensional view of our surroundings. It also provided us or anyone working on the investigation with a powerful tool to help re-construct a chain of events. Videotaping was also being introduced more and more in courts of law, making a strong visual impact on the jury. This proved very effective when shock and disgust was the reaction the prosecution was aiming at.
We divided other tasks to avoid stepping on each others’ toes and to minimise risk of contamination of the exhibits collected. At no time should two pieces of evidence come into contact with one another.
Frank was outside taking the overall and mid-range photographs of the location, including the street sign with the name clearly identified, the front the apartment, and close-ups of any points of interest. Later, if this homicide ever ended up in court, we would have to prove not only how we collected the exhibits, but also where we collected them from.
I took the initial photographs of the immediate crime scene. This had to be done before the removal of Mr Wilson’s body. I recalled that pictures of Mrs Wilson should have been taken before she was sent to hospital, but in the condition we found her, I felt at the time photographing her could wait.
I circled Mr Wilson’s body and took as many pictures as humanly possible, including close-ups of all visible wounds, bruises, cuts, hands and fingernails. More shots would be taken at the mortuary. For every photograph taken, I used an identifying scale or ruler whenever possible, and made appropriate notes whenever I deemed it necessary.
I noticed that the open wound above the chest where Mr Wilson’s head had been severed had stabilised. Although the body was drenched in a pool of blood, making it very difficult to take photographs without causing a mess, little blood was now running from the neck wound. I took shots at various angles and under different light conditions with the help of a portable flash.
I then proceeded with
