“We’re happy to help,” John said in his new persona. “But I want to emphasize that just because the toxicology screen is so far negative, it doesn’t necessarily mean there is none present. With some of the more potent agents, so little is needed to kill someone that the only way to identify it is to look for it specifically. What I’m trying to suggest is that if you have any reason to suspect a specific agent, you have to tell us, and we’ll specially look for it. Even then we can’t guarantee success, even with the trick of running the sample through the mass spec twice.”
“I understand,” Laurie said, and she did. She had been involved in several poisonings over the years. One had involved finding the agent at the crime scene, the other by discovering evidence that the perpetrator had purchased the material. But in her current case, neither of those opportunities was available.
“We’re not totally finished,” John added. “If we find something, I’ll be sure to give you a call.”
Next Laurie went down to the fourth floor and entered the histology lab, bracing herself for Maureen O’Conner’s invariable humor. She was not disappointed, nor was she disappointed about getting her slides overnight. As usual, Maureen came through with both.
Descending yet another floor, Laurie entered her office, eager to get to work. In order not to be bothered, she shut her door, which she rarely did. Next she deposited the tray of histology slides next to her microscope and turned on her monitor.
Her final act of preparing to get to work was to take out her cell phone and give Leticia a call. She actually felt proud of the fact that she’d resisted calling until almost ten. She thought it showed marked restraint, at least in comparison to the previous day. Leticia agreed.
“I’m surprised you didn’t call earlier,” Leticia said teasingly when she first answered.
“I’m surprised myself. How are things going?”
“Couldn’t be better. We’re staying in this morning, then going out to the park this afternoon. The sun is supposed to come out after noon.”
“Sounds like a plan,” Laurie said. While she had been talking to Leticia, she’d gotten out the photo she’d made from the security tapes and compared it to the photo in the new case file. It seemed that there was a definite resemblance between the man she’d just autopsied and one of the men in the photo. Actually, more than she expected.
After hanging up with Leticia, Laurie got the two security disks out of her bag and slipped the first into the DVD drawer. Then she put the photograph of the floater next to the monitor to make it easy to compare. With her mouse, she advanced the DVD to the appropriate time and pressed play.
The image was from camera five, and the timing was that of the victim rushing down the stairs to the subway platform. Within seconds, the two pursuing men appeared at the top of the stairs. At that point, Laurie stopped the action and then moved it forward frame by frame. As the action advanced and the men became larger and larger, Laurie alternately got a good view of first one and then the other. Although the two men resembled each other in terms of size and dress, one had a more or less full, oval face, while the other’s was lean and narrow. Of course, the more obvious difference was that the thinner man was carrying an umbrella, while the full-faced one was not.
Laurie advanced the frames until she had the best view of the full-faced man, as it was clear the man she’d just autopsied also had a full, oval face. At that point, with the security tape halted, she picked up the photo of the tattooed gentleman in the cooler and put them side by side.
For several minutes Laurie stared alternately at the photo and the image on her monitor. In a sense, she was disappointed. From the initial comparison using the photo she’d made at home and the photo taken at OCME, she’d been optimistic and had counted on the identification being easy: It was going to be either a yes or a no. She hadn’t expected a maybe, which seemed to be the situation. It was close. Alternately she looked at photos and then at the monitor image, again advancing the monitor image a frame at a time.
Still not certain, perhaps due to the dark glasses, Laurie quickly advanced the security tape to camera six and went to the same time sequence as she’d been on camera five. From that angle, something she’d not seen on camera five appeared. The man had a mole about the size of a dime on his right temple. It wasn’t particularly obvious, but it was definitely there, no doubt about it. Checking the photograph of the right profile on the photo, there it was as well! Laurie was reasonably confident that the two people were one and the same!
She sat back in her chair, amazed at the coincidence. Then she sat forward again and continued watching the tape from the sixth camera to the point where the train pulled into the station. Although it was not easy to make out because of the crowd surging forward toward the arriving train, Laurie tried to see exactly what happened when the two pursuers reached the victim. She could not see any of their hands, but quickly the two men seemed to be supporting the victim while the victim appeared to be convulsing. It was very fast, only a couple of frames. What wasn’t clear was whether the pursuers caused the victim to convulse or it was spontaneous, like a heart attack or stroke.
Laurie sat back in her chair again, watching the rapid denouement with the pursuers laying the now unconscious man onto the platform, having already stripped him of his bag and presumably his wallet. On this viewing, Laurie also saw something else she hadn’t made note of the previous evening: how the oval-faced man, after relieving the victim of his belongings, carefully picked up the umbrella and opened it about halfway before closing it again. The impression was that it took some force to get it closed. The thought that immediately came to Laurie’s mind was that the umbrella was being cocked like an air rifle.
Halting the security tape, Laurie was about to view the same sequence from the vantage point of some of the other cameras when a specific remembrance flashed through her mind. It was about a famous forensic case that she’d heard about in a lecture when she was a resident in forensic pathology. It involved the assassination in London of a diplomat from an Iron Curtain country she couldn’t remember. It was carried out with the help of an air gun cleverly hidden by the KGB within an umbrella.
Putting down the photos that she was still holding, Laurie went online and did a quick search, and within seconds she was reading about Georgi Ivanov Markov, a rather famous Bulgarian at the time, who had indeed been murdered with a KGB-manufactured pellet gun hidden within the shaft of an umbrella. Most important, Laurie learned that the substance involved was ricin, a remarkably toxic protein derived from castor beans.
Going back to the Web, Laurie looked up ricin, particularly interested in the symptoms associated with ricin poisoning. Immediately she could tell that her case of the previous day could not have been a copycat of the Markov incident, at least not with ricin, as ricin caused gastrointestinal symptoms, and the symptoms developed over hours, not instantaneously, as with her case. As far as the delivery aspect, however, meaning a pellet gun in an umbrella, that was a definite possibility. Laurie was now eager to repeat the external exams.
Why she hadn’t done a better external exam at the time, even if Southgate had supposedly done it and reputedly had called it negative, she didn’t know. In fact, from her current vantage point she was embarrassed she hadn’t done her own. Not long into the autopsy, her intuition was telling her it had not been a natural death, as there was no pathology at all: none! The challenge now was to prove her intuition was correct: whether there was a tiny entrance wound that he’d received through his clothing.
Laurie picked up the phone and called Vinnie’s cell. She and most people at OCME had been finding that using personal cell phones was significantly more efficient than using the regular internal phone lines. She wondered if Vinnie’s mood had improved. He answered after the first ring.
“How about my Asian John Doe?” Laurie asked. “Is he ready for another look?”
“A table is just opening up,” Vinnie said. “It should be within a half-hour or so.”
“Terrific! Should I just come down in a half-hour, or do you want to give me a call?”
“If you don’t mind, I’ll have Marvin give you a call,” Vinnie said, continuing to suffer guilt about his very real fears of having been caught in an untenable situation where he was damned if he did and damned if he didn’t. If he went to Laurie and took responsibility for sending her the threatening note and tried to convince her about what to do, he and/or his family, particularly his girls, would surely be harassed if not killed. If he didn’t do anything and Laurie didn’t heed the message, she could be killed. The situation was driving him to distraction. “He’s available now, and I know you guys like to work together.”
“Suit yourself!” Laurie said, finally truly irritated. It seemed to her that Vinnie had been trying to provoke her all morning, and now he’d succeeded.
Calming herself down, Laurie turned to the histology slides. Until she’d viewed all of them, particularly the sections involving the brain and the heart, and found nothing, there was still a slight chance yesterday’s case was a natural death, despite her intuition to the contrary. Last night she’d become excited over the case. Now she was
