So much crime was committed in Los Angeles that the LAPD lab was backlogged for months. Priorities were given to hot cases and cases going to trial, but the backlog was still so great that LAPD set up an experimental program called Walk-in Wednesday. Every Wednesday, detectives could hand-carry evidence to the lab on a first-come first-served basis to cut through the red tape. But there were still so many cases that the waiting rooms were crowded with loitering detectives.

I said, "Something like that. I have a friend at SID who owes me a favor."

"The little creep who worked with the key card?"

"Yeah, Pardy, him."

The little creep. Chen would love it.

I explained how Thomas came to take the picture, and that a couple of hundred pictures just like it were in the computer. Diaz and Pardy listened as I went through the terms of the deal, then Diaz arched her eyebrows at Pardy.

"You'd have to turn it over to Southwest Bunco, but it would still look good. I think we should go for it."

"Do whatever you want."

Diaz stared at him, and was clearly annoyed.

"Listen, Pardy, don't drop the ball here. This could turn into a major investigation with the Feds. You should get a piece of that. You should develop the case to see what you have before you hand it off. That way, you get more of the credit."

Pardy had resumed his slouch, and stared at her with sleepy eyes.

"I'm busy. You develop it if you want."

Diaz looked as if she was going to say something more, but turned back to the laptop and angled the screen for a closer look.

"Okay, fuck it. We get this cleaned up, it might be good for a registration. I want to get this over there right away."

"Are you good with the pass for Thomas and Dana?"

"We're good, but not if they had anything to do with the murder. Everything about this killing stinks like sex to me. If it turns out they had something to do with the murder, all bets are off."

Pardy said, "It wasn't about sex."

He was slouched back in the chair with his arms crossed and his legs out, looking like he was about to fall asleep. Diaz's mouth tightened with irritation.

"Okay, genius, what do you think it was?"

"A straight-up murder."

Diaz swiveled to face him, and Pardy went on.

"I haven't been sitting on my ass, Diaz. A witness ID'd Reinnike at Union Station about an hour before he was killed. Described the tats on his hands, and picked his face from a six-pack."

"What witness?"

"Homeless dude I know from Metro. Reinnike was hanging around, he said. My guy hit him up for a handout, and Reinnike came across. I'm thinking if Reinnike was at Union Station, he was meeting someone."

Maybe Pardy looked sleepy because he had been working the case all night.
