‘Thanks, Leon. Any other comments?’
Simon, already the devil’s advocate designate of the group, weighed in, his Glasgow accent and habit of staring out from under his heavy dark eyebrows multiplying the aggression factor. ‘You could argue that that’s because the kind of woman who indulges in these kind of sports is exactly the sort that’s confident enough to be out in risky places on her own, convinced it’s never going to happen to her. It could easily be two, three or even four attackers. In which case, bringing in a profiler is going to be a total waste of time.’
Shaz shook her head. ‘It’s not just the victims,’ she stated firmly. ‘If you read their evidence, in each case their eyes were covered during the attack. In each case, they mention that their assailant verbally abused them continually while he was actually assaulting them. That’s more than sheer coincidence.’
Simon wasn’t ready to give up. ‘Come on, Shaz,’ he protested. ‘Any bloke who’s so powerless he needs to resort to rape to feel good about himself is going to need to talk himself up to it. And as for their eyes being covered – there’s nothing in common there except with the first and third where he used their own headbands. Look –’ he waved the papers – ‘case number two, he pulled her T-shirt over her head and tied a knot in it. Case number four, the rapist had a roll of packing tape that he wound round her head. Way different.’ He sat back, a good-natured grin defusing the force of his words.
Tony grinned. ‘The perfectly contrived lead into the next subject. Thanks, Simon. Today, I’m going to hand out your first assignment, the preamble to which is the beginner’s guide to signature versus MO. Anybody know what I’m talking about?’
Kay Hallam, the other woman on the team, raised her hand half a dozen inches and looked questioningly at Tony. He nodded. She tucked her light brown hair behind her ears in a gesture he’d come to recognize as Kay’s keynote mechanism for looking feminine and vulnerable to defuse criticism, particularly when she was about to make a point she was absolutely sure of. ‘MO is dynamic, signature is static,’ she said.
‘That’s one way of putting it,’ Tony said. ‘However, it’s probably a bit too technical for the plods among us,’ he added with a grin, pointing his finger one by one at the other five. He pushed back his chair and started moving restlessly round the room as he talked. ‘MO means modus operandi. Latin. The way of doing. When we use it in a criminal context, we mean the series of actions that the perpetrator committed in the process of achieving his goal, the crime. In the early days of profiling, police officers, and to a large degree psychologists, were very literal about their idea of a serial offender. It was somebody who did pretty much the same things every time to achieve pretty much the same results. Except that they usually showed escalation, moving, say, from assaulting a prostitute to beating a woman’s brains out with a hammer.
‘As we discovered more, though, we realized we weren’t the only ones capable of learning from our mistakes. We were dealing with criminals who were intelligent and imaginative enough to do exactly the same. That meant we had to get our heads round the idea that the MO was something that could change quite drastically from one offence to the next because the offender found that a particular course of action wasn’t very effective. So he’d adapt. His first murder could be a strangulation, but maybe our killer feels that took too long, was too noisy, frightened him too much, stressed him rather than allowing him to enjoy his fulfilment. Next time out, he smashes her skull in with a crowbar. Too messy. So number three, he stabs. And the investigators write them off as three separate killings because the MO looks so different.
‘What doesn’t change is what we call, for the sake of giving it a name, the signature. The sig, for short.’ Tony stopped pacing and leaned against the window sill. ‘The sig doesn’t change because it’s the raison d’être of the offence. It’s what gives the perpetrator his sense of satisfaction.
‘So what does this signature consist of? Well, it’s all the bits of behaviour that exceed what is actually necessary to commit the crime. The ritual of the offence. To satisfy the perpetrator, the signature elements have to be acted out every time he goes out on a mission, and they have to be performed in the same style every time. Examples of signature in a killer might be things like: does he strip the victim? Does he make a neat pile of the victim’s clothes? Does he use cosmetics on the victim after death? Is he having sex with the victim postmortem? Is he performing some kind of ritualistic mutilation like cutting off their breasts or penises or ears?’
Simon looked faintly queasy. Tony wondered how many murder victims he’d seen so far. He would have to grow a thicker skin or else be prepared to put up with the jibes of colleagues who would enjoy watching the profiler lose his lunch over another vitiated victim. ‘A serial offender must accomplish signature activities to fulfil himself, to make the act meaningful,’ Tony continued. ‘It’s about meeting a variety of needs – to dominate, to inflict pain, to provoke distinct responses, to achieve sexual release. The means can vary, but the end remains constant.’
He took a deep breath and tried to keep his mind off the very particular variations he’d seen at first hand. ‘For a killer whose pleasure comes from inflicting pain and hearing victims scream, it’s immaterial whether he …’ his voice faltered as irresistible images climbed into his head. ‘Whether he …’ They were all looking at him now and he desperately struggled to look momentarily distracted rather than shipwrecked. ‘Whether he … ties them up and cuts them, or whether he …’
‘Whether he whips them with wire,’ Shaz said, her voice casual, her expression reassuring.
‘Exactly,’ Tony said, recovering fast. ‘Nice to see you’ve got such a tender imagination, Shaz.’
‘Typical woman, eh?’ Simon said with a grunt of laughter.
Shaz looked faintly embarrassed. Before the joke could escalate, Tony continued. ‘So you might have two bodies whose physical conditions are very different. But when you examine the scenario, things have been done that were additional to the act of killing and the ultimate gratification has been the same. That’s your signature.’
He paused, his control firmly in place again, and looked around, checking he was taking them all with him. One of the men looked dubious. ‘At its most simplistic,’ he said, ‘think about petty criminals. You’ve got a burglar who steals videos. That’s all he goes for, just videos, because he’s got a fence who gives him a good deal. He robs terraced houses, going in through the back yard. But then he reads in the local paper that the police are warning people about the video thief who comes in through the back yard, and they’re setting up neighbourhood watch teams to keep a special eye on back alleys. So he abandons his terraced houses and instead he goes for between-the-wars semis and gets in through the side windows in the downstairs hall. He’s changed his MO. But he still only nicks the videos. That’s his signature.’
The doubter’s face cleared. Now he’d grasped it. Gratified, Tony picked up a stack of papers divided into six bundles. ‘So we have to learn to be inclusive when we’re considering the possibility of a serial offender. Think “linking through similarity”, rather than “discounting through difference”.’
He stood up again and walked around among their work tables, gearing himself up to the crucial part of the session. ‘Some senior police officers and profilers have a hypothesis that’s more confidential than the secrets of the Masonic square,’ he said, capturing their attention again. СКАЧАТЬ
