CHAPTER 26
Mr 11-5 knows what he's doing, Lincoln Rhyme reflected yet again, as he guided his Merits to the evidence examination table, where Mel Cooper and Sachs were examining the evidence from the hospital.
Despite her exhaustive search of the corridors, the doctors' office building and the 'skin museum', the evidentiary findings from the abortive assault on Harriet Stanton were minimal.
There were no friction ridges; he'd been clever enough not to actually touch Harriet with his fingers (prints can be lifted off skin). He'd either gripped only her clothing or touched her flesh with his sleeves. And somewhere between fleeing the site of the attack in the basement and his slipping into the specimens room, he'd pulled on latex gloves (not vinyl, which display distinctive wrinkle patterns that can be introduced at trial).
But unlike the earlier scenes, he'd been taken by surprise, so he didn't have the chance to don booties. Sachs got some good electrostatic footprints.
Size eleven Bass shoe, though that meant only that he was wearing a size eleven Bass shoe, not that he had size eleven feet.
The wear pattern of the tread marks, which sometimes could give details about weight and posture, didn't reveal much but, Rhyme reflected, who cared? They knew his weight and posture.
Sachs rolled the floor around the footprints for trace, just in case. But Mel Cooper reported that the analysis revealed, 'A lot of Inwood marble and more of the cleanser and medical materials that had led us to the hospital in the first place. Some of the cleanser again. Nothing else.'
She had found some unique trace in the specimens room, identified by the chromatograph/spectrometer as dimethicone, which was used in cosmetics and industrial lubricants and processed foods to prevent caking. Interestingly it was also the primary ingredient in Silly Putty. Rhyme didn't dismiss this fact immediately but after some consideration decided that the novelty toy didn't figure in the unsub's plan.
'I think he picked dimethicone up when he grabbed Mrs Stanton.' Sachs explained that, as a woman in her fifties, she had worn a fair amount of makeup. Sachs dug out her mobile and called the number Harriet had given her. She answered and, after Sachs gave her an update of the case, got the brand name of the woman's preferred makeup products. Running the manufacturer's website, Sachs learned that dimethicone was in fact one of the ingredients in her foundation.
Dead end there.
And no other trace or fibers.
As she wrote the details up on the whiteboard chart Sachs said, 'One other thing. I saw he had a tattoo on his--' She frowned. 'Yes, his left arm. An animal or some kind of creature. Maybe a dragon. From that thriller book. The Dragon Tattoo. In red.'
'Right,' Sellitto added, looking at his notebook. 'Harriet Stanton said he had one. She didn't see what it was, though.'
'Any trace of the poison he intended to use on the vic?' Pulaski asked Cooper.
'Nothing. No toxins on anything that Amelia collected.'
'I think we can assume he keeps his love potions sealed up until he's ready to start using them.' Rhyme was wondering again: Why that MO? Poison was a rare murder weapon now. The technique of killing with toxins, popular through the ages, began to fall out of fashion long ago, in the mid-1800s, after the famed English chemist James Marsh invented a test that could detect arsenic in tissue postmortem. Tests for other toxins soon followed. Homicidal husbands and greedy heirs, who'd believed that doctors would rule cause of death coronary or stroke or illness, began ending up in prison or on the gallows after early forensic detectives presented their cases in court.
Some substances like ethylene glycol - automotive coolant - were still fed to husbands by unhappy wives, and Homeland Security worried about all sorts of toxins as terrorist weapons, ranging from castor beans turned into ricin, to cyanide, to botulinum, which was the deadliest substance in existence (a very mild form of which was used in cosmetic Botox injections); a few kilograms of botulinum could kill every person on earth.
Yet poisons were cumbersome and detectable and hard to administer, not to mention potentially lethal to the poisoners. Why do you love them so much? Rhyme sile
ntly asked the unsub.
Mel Cooper interrupted his musings. 'It was a close call at the hospital. Do you think he'll go away?'
Rhyme grunted.
'That means no?'
Sachs interpreted. 'That means no.'
'The only question,' Rhyme said, 'is where's he going to strike next?' He wheeled to the board. 'The answer's there. Maybe.'
