When Dickinson walked into CID just before shift change in Tuesday, he found Ed McCarley waiting for him in the hallway.
"Have a good day off, rook?" McCarley said - in his usual passive-gruff voice.
Dickinson smiled when he saw his old FTO, if only because Ed was his favorite cop in the world. "What's up? You look worried."
"Maybe because I am. There was another one, late Saturday, early Sunday."
"What? Where? We were supposed to get a call if..."
"Your witness, in her apartment. She and her boyfriend...cruciform knife wounds and a container of..."
"Let me guess," Sawyer said, stepping out of the locker room, "cottage cheese and green onions." She was holding up a copy of the report as she walked up to them. "We were watching the place after we dropped her off. Took her by Fair Park, got some tickets and an arm band, kind of an alibi, I guess."
"It didn't work," McCarley said.
"I don't get it," Dickinson added. "We dropped her off then set right up; her door wasn't out of sight for more than a minute. That means our perp waited for us to leave..."
"Or she was already there before we dropped her off."
"That would mean she went straight there, from the peep show," Ed said. "So, the perp saw her, that's for sure."
"Yup," Sawyer sighed, reading through the report. "And she was well known to them, both to Sam and her boyfriend."
"That's why I'm here," McCarley said. "I've had a few encounters with Darius Jenkins. That's her boyfriend, in case you haven't read that far," McCarley sighed. "Jock over at SMU, blew his knee and went into dealing full time after that. Runs a few girls, too, mainly underage dark meat to hotels out on Hines."
"On Harry Hines?" Dickinson asked. "That's where our..."
"Probably coincidence," Sawyer growled, turning a page and reading. "Another syringe cap, same brand and size. I'm thinking a disgruntled nurse, maybe recently fired?"
"So," Dickinson added, "female white, mid-twenties, short brown hair?" And we've got her Identikit drawing, too. Assuming..."
"Assuming she was straight with us. I think she was protecting her dealer," Sawyer added.
"Then why'd she narc her out to begin with?"
"Cover her own ass, when the victim was found."
McCarley nodded. "That fits. Also, my rook and I found a wig in a dumpster Sunday, about two blocks away."
"Blond?"
"That's right."
"Damn."
"Yeah. Whoever this is, she's planning them real good, right down to her escape and evasion routes. She's thinking things through, sticking to her plan."
"So, a medical worker with possible military training? Like a medic?"
"Good place to start," McCarley said. "My rook and I are floating tonight. I think we'll work Harry Hines - in an unmarked."
"What unit are you?" Sawyer asked.
"2171."
"Okay, we're 320, and we'll check in with you on 2."
"Got it," McCarley said as he walked off to his shift's patrol briefing.
"Well, let's face the music," she said, walking into CID's evening shift briefing.
+++++
McCarley and his rookie, Pat Patterson, checked out a '76 Chevy Monte Carlo from the garage and turned out for Harry Hines in the early afternoon rush. Downtown would be last to flush out of the skyscrapers, but all the ancillary services around downtown were pouring onto the streets now, and traffic was already heavy as they made their way past the Old Red Courthouse and Dealey Plaza.
"Hard to believe it happened right here," Patterson said, looking up at the window in the old school book depository where Oswald had leaned out and fired three shots that changed the world. "Were you here then?"
"I'm old, Meathead, but not that old."
"Sorry."
"So. Someone in the medical field. Short, brown hair, not real tall, not fat, not skinny. No vehicle. Possibly military, maybe a medic at one point. First murder was near Oak Lawn, near the old SO building..."
"SO?"
"The old Sheriff's Office, Oak Lawn and Maple. Wasn't a mile from where it happened, so maybe she knows the area. Works or lives around here."
"Well, that means Parkland," Patterson said, turning onto the convoluted ramp that led under the railroad tracks and up to Stemmons Expressway.
"So..." McCarley said - thinking out loud, "what's at Parkland? The hospital, the MEs office..."
"There's a medical school, too," Patterson added. "What would an Army medic try to do after getting out of the military?"
"Go into nursing?"
"Or try for med school."
McCarley looked at Patterson, nodded his head. "You know where it is?"
"The med school? No, not really."
"Get off on Inwood," McCarley added, then he guided Patterson to the med school. "Okay, let's just cruise, see what we can see."
After ten minutes they stopped, parked under a live oak tree and watched the two parking areas they had found reserved for students...
"320, 2171 on two."
McCarley picked up the mic: "71, go."
"20?"
"UT Southwestern, scoping out the student parking lots."
"4."
He put the mic back in it's holder and looked at a bunch of kids coming out of one of the classroom buildings, zeroed in on two girls with short brown hair. One walked over to a vaguely yellow Honda Civic, the other to a white Mustang convertible, and he hefted a pair of binoculars to his face and called out the license plate numbers to Patterson, who then ran the numbers through dispatch.
"320, 71, whatcha got?"
"Short brown hair, one getting in a Civic, the other in a Mustang convertible."
"What color is the Mustang," Sawyer asked, thinking of the girl in May's CafΓ© on Sunday.
"White."
"Get on her, now."
"4," McCarley replied. "What's up?"
"Girl in a white Mustang convertible showed up where we were eating Sunday, scoped us out pretty good..."
"2171, have your 28 on 330-Paul Adam Ida."
"71, go ahead."
"Comes back to Rebecca Lykes, address on Belclaire, Highland Park."
"Can you pull a 27?"
"Standby."
"320, 71, you on her?"
"4."
"4. Code 5." Sawyer looked at Dickinson. "Couldn't be this easy, could it?"
"Nope." Dickinson cut through traffic, made it over to Harry Hines in a hurry.
"2171, have your 27 info on Lykes, Rebecca C, DOB 8-8- 59, no history, no CCH, no wants or warrants."
