“
Your wife?” “Right.” “What does she do?” Tracy asked. “She works for a janitorial company; they clean the buildings downtown.” “She works nights?” Kins said. “Yeah.” “Do you have kids?” Tracy asked. “A daughter.” “Who watches your daughter when you and your wife are working nights?” “My mother-in-law.” “Does she stay at your house?” Tracy said. “No, my wife drops her off on her way to work.” “So nobody was at home when you got there Sunday night?” Bankston shook his head. “No.” He sat up again. “Can I ask a question?” “Sure.” “Why are you asking me these questions?” “That’s fair,” Kins said, looking to Tracy before answering. “One of our labs found your DNA on a piece of rope left at a crime scene.” “My DNA?” “It came up in the computer database because of your military service. The computer generated it, so we have to follow up and try to get to the bottom of it.” “Any thoughts on that?” Tracy said. Bankston squinted. “I guess I could have touched it when I wasn’t wearing my gloves.” Tracy looked to Kins, and they both nodded as if to say, “That’s plausible,” which was for Bankston’s benefit. Her instincts were telling her otherwise. She said, “We were hoping there’s a way we could determine where that rope was delivered, to which Home Depot.” “I wouldn’t know that,” Bankston said. “Do they keep records of where things are shipped? I mean, is there a way we could match a piece of rope to a particular shipment from this warehouse?” “I don’t know. I wouldn’t know how to do that. That’s computer stuff, and I’m strictly the labor, you know?” “What did you do in the Army?” Kins asked. “Advance detail.” “What does advance detail do?” “We set up the bases.” “What did that entail?” “Pouring concrete and putting up the tilt-up buildings and tents.” “So no combat?” Kins asked. “No.” “Are those tents like those big circus tents?” Tracy asked. “Sort of like that.” “They still hold them up with stakes and rope?” “Still do.” “That part of your job?” “Yeah, sure.” “Okay, listen, David,” Tracy said. “I know you were in the police academy.” “You do?” “It came up on our computer system. So I’m guessing you know that our job is to eliminate suspects just as much as it is to find them.” “Sure.” “And we got your DNA on a piece of rope found at a crime scene.” “Right.” “So I have to ask if you would you be willing to come in and help us clear you.” “Now?” “No. When you get off work; when it’s convenient.” Bankston gave it some thought. “I suppose I could come in after work. I get off around four. I’d have to call my wife.” “Four o’clock works,” Tracy said. She was still trying to figure Bankston out. He seemed nervous, which wasn’t unexpected when two homicide detectives came to your place of work to ask you questions, but he also seemed to almost be enjoying the interaction, an indication that he might still be a cop wannabe, someone who listened to police and fire scanners and got off on cop shows. But it was more than his demeanor giving her pause. There was the fact that Bankston had handled the rope, that his time card showed he’d had the opportunity to have killed at least Schreiber and Watson, and that he had no alibi for those nights, not with his wife working and his daughter with his mother-in-law. Tracy would have Faz and Del take Bankston’s photo to the Dancing Bare and the Pink Palace, to see if anyone recognized him. She’d also run his name through the Department of Licensing to determine what type of car he drove. “What would I have to do . . . to clear me?” “We’d like you to take a lie detector test. They’d ask you questions like the ones we just asked you—where you work, details about your job, those sorts of things.” “Would you be the one administering the test?” “No,” Tracy said. “We’d have someone trained to do that give you the test, but both Detective Rowe and I would be there to help get you set up.” “Okay,” Bankston said. “But like I said, I have
