off?â
âBig-time. Heâs the S all the way. Wants to be the hurter, not the hurtee.â
Lily explained about his personal Pinterest album. âJesus, took all my willpower not to kick him in the balls. You shouldâve seen what he did to some of those women.â
âHe pressure you two lovely ladies to go home with him?â Lucas asked.
âSure, but we had to postpone our threesome. Somehow his glass kept getting refilled. He was in no shape to tie anybody up after that much bourbon. I was tempted to let the asshole stagger home and hope some mugger beat the crap out of him. But Amelia was the mature one and we got him into a cab.â
Sachs glanced at the plastic bags. âWhat does the evidence say?â
âJust getting it now,â Lincoln told her, and grumbled, âRight, Mel? It seems to be taking forever.â
Mel Cooper, hunched over a computer monitor, didnât respond. He shoved his glasses higher on his nose and said, âInteresting.â
âThatâs not a useful term, Mel,â Lincoln snapped.
âIâm getting there. Lucas collected five different kinds of bronze from Verlaineâs. One is typical modern formula: eighty-eight percent copper and twelve percent tin. Then alpha bronze, with about four to five percent tin.
âSome other samples have a higher concentration of copper and zinc and some leadâthatâs architectural bronze. Others are bismuth bronzeâan alloy thatâs got a lot of nickel, and traces ofbismuth. One sample surprised meâit had a Vickers hardness value of two hundred.â
âThatâs the bronze used in swords,â Lucas said.
They all looked at him. âFor the role-playing games I write. Helps to know about old-time weapons. Roman officers had bronze swords; foot soldiers had iron.â
Amelia asked, âYou think he uses bronze as a weapon?â
Lucas shook his head. âNo, I think what it means is that he gets his materials wherever he can find them. Probably from dozens of junkyards and construction sites.â
âI agree,â Lincoln said.
Cooper added, âAnd thereâs triethanolamine, fluoroboric acid, and cadmium fluoroborate.â
âThatâs fluxâused in brazing and soldering,â Lincoln said absently.
âOkay, the big question: any associations, Mel?â Lucas asked.
In crime scene work, very few samples of evidence actually âmatched,â meaning they were literally the same. DNA and fingerprints established true identity but little else did. However, samples of evidence from two scenes could be âassociated,â meaning they were similar. If close enough, the jury could deduce that they came from the same source. Here, the team had to show that the shavings found in the first victimsâ bodies could be closely associated with those Lucas had collected from Verlaineâs studio.
Cooper finally pushed back from the screen. He didnât seem happy. âLike the concrete, the flux and welding rods are close to the trace from the earlier crime scenes.â
Lincolnâs face tightened into a frown. âBut those are used by anyone brazing, welding, or working with bronze. I want to establish identity with the bronze scraps themselves.â
âUnderstood. But thatâs more of a problem.â He explained thatfour of the bronze samples at the first crime scene were completely different from any of the metal collected by Lucas. One sample Lucas had collected that night had the same composition as several fragments in the first scenes. The others were similar but had âsome compositional differences.â
â How similar?â Lincoln snapped.
âIâd feel comfortable testifying that it was possible the scraps embedded in the victims came from Verlaineâs loft. But I couldnât do better than that.â
The evidence suggested but didnât prove that Verlaine was the
