Interactive CD-ROM Proficiency Testing and Training: Learning From Experience

Addendum A

The following information is provided by the Crime Scene Proficiency Advisory Committee to indicate the responses to the test. Assessment was also based on the notes; photographs; sketches; evidence collection, labeling, and packaging; witness interviews, and the overall sequence or audit trail collected in the After the Fact program.

Scenario: Rape Scene at a Motel

Date: March 15, 1999
Time: 2230 hours

Tracy Boulton, a businesswoman attending a training seminar, was staying at the Greenbank Motel, Greenbank, Australia, when she heard a knock on the door. Thinking it was the motel management, she opened the door and was confronted by a person wearing a disguise over his head, denim jeans, and a black shirt. Before she had time to fight back, she was tackled to the ground and an adhesive tape was placed over her mouth.

Tracy remembers being thrown onto the bed where she was assaulted and raped. She cannot remember anything more until she woke up 30 minutes later.

Upon waking, she telephoned the motel manager, Guy Pearce. She stated she had been assaulted and asked him to telephone police. Guy Pearce went to Tracy’s room, where the police found him when they arrived.

The police secured the scene by closing the door and leaving it locked with the keys in the possession of the motel manager, Guy Pearce. The police took Tracy to the closest medical clinic and contacted detectives.

Guy Pearce
My name is Guy Pearce, and I am the manager of the Greenbank Motel, Greenbank. On the night of the March 15, 1999, I was asleep on the premises. At approximately midnight, I answered a telephone call from Room 34. A female, Tracy Boulton, screamed that she had been assaulted and asked me to telephone the police. Naturally, I called the police and went to her room, where I stayed until the police arrived. On entering the room, I noticed that it was messy, and she was wearing a dressing gown. I did not touch anything in the room except to comfort Ms. Boulton.

First Aid Officer
My name is Senior Constable White from the Greenbank Police. My partner, Constable Paxton, and I responded to a call to the Greenbank Motel, where a distressed female stated that she had been assaulted and raped. We secured the room by locking the door and leaving the keys with the motel manager for the Criminal Investigation Bureau personnel who attended the next morning. We then took Ms. Boulton to the forensic medical officer for examination and contacted the rape squad. At no time did we touch or move anything in the room.

Tracy Boulton
My name is Tracy Boulton, and I live on my own at 34 Stephens Parade Canberra. I was in Melbourne for a training seminar and stayed at the Greenbank Motel. At approximately 10:30 p.m. on March 15, 1999, I answered a knock at my motel room door and was confronted by a large male wearing dark clothing, jeans, and a disguise on his head. I did not have time to yell because he hit me across the face and then gagged me. He forced himself onto me and raped me on the bed. I do recall trying to scratch or gouge at him. I cannot remember anymore because I must have passed out before I rang the motel manager.
