Richardson had advanced degrees in chemistry, forensic science, physiology, and pharmacology and had worked in the FBI lab since 1978, when he was assigned as an examiner in the Bureau’s chemistry and toxicology unit in Washington, D.C. “I’m also employed as the program manager for the FBI laboratory’s nuclear, biological, chemical, and its counter-terrorism program.”
“How long have you been program manager?” Morrison asked.
“Approximately three or four months . . . I have been involved in a leading role in the program since March of last year, with the Tokyo subway poisoning [in which members of the Aum Shinrikyo cult released nerve gas on a subway train]. I went to Japan two times and have been involved internationally and nationally in a variety of different things. . . . I’m also involved in terms of threat assessments of chemical and biological terrorist incidents that would be potential violations of federal law.”
Richardson had more than a passing knowledge of ricin. He had an insider’s knowledge of the Arkansas case where the man accused of smuggling ricin killed himself in jail.
“What is ricin?” Morrison asked, knowing that the answer was going to sound like so much gobbledygook to almost everyone in the courtroom.
“Ricin is a protein,” Richardson began. “It’s a two-chain protein weighing approximately 65,000 Daltons or atomic mass units. You might wonder what ‘65,000 atomic mass units’ mean. In order to get some relevance to that, drugs that we’re familiar with, such as cocaine, heroin, marijuana, and so forth, have a molecular weight of about 300 atomic mass units. So we’re talking about a very large compound. It’s a compound that largely occurs and is present in castor-bean plants. . . .”
“Is ricin toxic to humans?” Morrison asked.
“Yes, it’s very toxic.”
“What does that mean?”
“The toxicity of ricin is route dependent. There are several ways that one might be exposed to ricin. One could inhale it, one could actually take it orally . . . intramuscularly . . . subcutaneously; the toxicity is on the order of a few micrograms. Oral ingestion is considerably less toxic, in the range of perhaps a milligram per kilogram of body weight.”
There was no sound in the courtroom except Richardson’s voice and the frantic scribbling of two dozen pens.
Richardson explained that if ricin was administered by a shot, a lot less of it was needed to kill a human being than if it was swallowed. He said the poison’s only known source was the innocent-appearing castor bean.
“If I took a castor bean and just swallowed the whole bean and didn’t chew on it, would that kill me?” Morrison asked.
“Quite likely not. . . . The bean itself has a rather hard coating—shell—which would essentially protect one from ricin toxicity.”
“Ricin’s not in the shell?”
“That’s correct. It’s in the pulp of the bean itself.”
State’s Exhibits No. 11 and No. 12—the sample of Michael Farrar’s blood, and the packet of castor beans sent to the FBI lab—were shown to Richardson. He identified the sixteen beans in the Earl May packet—mottled reddish-brown seeds, shiny on the outside, with a white, pulpy, oily material inside—as castor beans. He had done a number of tests on them.
“And you performed some chemical assays to determine whether or not the insides of those beans contained ricin?”
“That’s correct.”
“And did they come up with a positive for that?”
“These were positive for containing ricin . . . in the percentage that the literature indicated should be in those beans.”
“You said that the literature said those beans would have between one and five percent ricin?”
“That’s correct. And those had two to three percent.”
“Has ricin been used in mystery novels as an agent of death?” Morrison asked.
“Probably the most notable in terms of ricin,” Richardson answered, “which could well have been a fictional account—but in fact turned out to be a real account—was one involving an individual named Markov, a . . . defector from Communist Bulgaria in 1979 or 1980. He was living in Great Britain at the time, was a writer and a speaker, and happened to be saying unkind things about the Communist regime in Belgrade on Radio Free Europe and the BBC. . . . He was poisoned by being stabbed in the thigh with a James Bond type of device, an umbrella that injected a combination of ingredients containing about half a milligram of ricin. He succumbed about three days later.”
Richardson explained that one didn’t need a scientific background to poison someone with ricin. “In the underground terrorist literature, there are simple cookbook solutions of how to do this.”
“And one way to do it would be to mash the beans up?” Morrison asked.
Richardson said that would make it easy to administer ricin orally.
“What’s going to happen to that person?”
“A variety of things—both at a biochemical and a molecular level . . . At a molecular level, the effects of ricin inhibit protein synthesis, which is important to cell function. It’s also a lectin [a protein found in plant seeds] that is going to cause cell agglutination [clumping together] and breakdown of red blood cells at a tissue level. It’s going to cause organ toxicity in the liver and pancreas. And the general toxic nature orally: vomiting, nausea, diarrhea, gastroenteritis, hemorrhagic enteritis, bleeding in the GI tract . . .”
Richardson testified that he had reviewed Dr. Michael Farrar’s medical records, producing an instant flurry of objections from the defense. Moriarty objected on the grounds that Richardson was not a medical doctor and could not give a diagnosis on the basis of the 150-page stack of medical records.
“Judge,” Morrison said. “I’m not going to ask him if he has an opinion whether or not . . . [Michael Farrar was] ricin poisoned, based on those records.”
Ruddick nodded. “Well, I think we’re ready for the next question.”
“Do you,” Morrison asked Richardson, “have an opinion on the symptomatology on those medical records? Is [it] consistent or inconsistent with ricin poisoning?”
“I found them to be consistent with ricin poisoning. I found nothing to be inconsistent with ricin poisoning.”
The courtroom buzzed, but Debora, as usual, stared at the witness, her face a mask.
It was time for the noon recess. Frustrated, Morrison lapsed into the Kansas vernacular. “Judge, I’m not near close to being done with him.” But whatever further questions he had for Richardson would have to wait.
Lunch hours were short. There was no time to leave the county complex; spectators, lawyers—even the judge himself—walked across the quadrangle, heads bent against the icy wind, toward the basement cafeteria in the administration building. If anyone who knew her recognized Celeste Walker sitting in the least conspicuous corner of the cafeteria, nobody gave her away by acknowledging her. Mike had not returned to the courtroom after his testimony the day before—nor would he. Celeste did not yet know if she would be called to testify, and so she waited.
At 1:15, Drew Richardson was back in the witness chair. His morning testimony had shown him to be a scientist, who often gave overlong answers while the gallery waited to hear if he would answer the one question that truly mattered: Had he found ricin antibodies in the samples of Mike’s blood sent to him from Johnson County, Kansas?
But Richardson would not be hurried. He testified that ricin enters the victim’s tissues rapidly and does damage there, sometimes causing “cell death.”
Morrison, patient, but anxious to translate Richardson’s testimony into lay terms, asked, “I guess what I’m getting at is—let’s say I was poisoned with ricin and I survived. If I was brought to you or some other chemist or physician, let’s say a week or two weeks later, would you be able to perform some sort of a test on me that would be able to tell you whether or not ricin is present in my bloodstream or in my tissue or whatever?”
“It’s quite unlikely,” Richardson said. Unless the ricin had been injec
ted. If it had been swallowed, ricin would remain undetectable for a much longer time.
“Now,” Morrison asked, “if it was a month or two after the ricin had been administered—let’s say orally, for example—would it be fair to say that it would be difficult, if not impossible, to find it?”
“Yes. Certainly in a nonlethal situation.”
And, somehow, Mike had survived.
“Now, are there ways to analyze tissues of the body to detect whether ricin has been there?” Morrison asked.
“Yes.”
“How would you do that?”
It was fascinating to watch these two men, both trying to present the same information to Judge Ruddick. Morrison was searching for lay terms; Richardson had difficulty speaking in anything but scientific jargon. They arrived at a system: Richardson would speak and Morrison would translate. It was so desperately important for the prosecution to show that Mike had been systematically poisoned by castor beans like those found in Debora’s tote bag. Proof of that would reveal a heedless side of her personality, would show how far she would go for revenge.
Richardson began another long answer, explaining how he tested for ricin in the human body.
“One would indirectly analyze for ricin exposure by looking for antibodies. . . . Ricin . . . is a protein. It is a toxin. It is also known as an antigen. . . . An ‘antigen’ is actually an abbreviation for ‘antibody genesis.’ A compound the size of ricin, and with the structure, et cetera—the nature—of ricin, would produce an antibody response. One. Not only an antibody from a class of antibodies, but produce a very specific lock-and-key fit—an antibody specifically and uniquely designed and structured to fit the structure of ricin.”
“Are antibodies in our blood?” Morrison asked.
“Yes.”
“Pardon me for being so very, very, basic here,” Morrison interrupted. “Would it be fair to say that an antibody is in the body to defend against attacking substances to the body—in the bloodstream? Correct?”
“That’s correct. It’s also a protein in nature, and a multi-charged protein.”
That wasn’t really information Morrison needed. Heads began to shake in the gallery, and Judge Ruddick was listening hard for what he needed to know.
“Let’s say”—Morrison was trying to translate again—“I’m being poisoned with ricin and I survive. What you’re telling me is that if ricin gets in my bloodstream . . . my body is going to build antibodies to defend against the invader. Correct?”
“That’s correct.”
“Those antibodies—do they disappear as soon as that invader’s gone, or is it something that’s going to stay with me forever?”
Richardson said that one dose of ricin would likely produce a very small amount of antibody. However, someone exposed a second time—and then a third—would produce more antibodies, which might last for months or even years. Furthermore, there was a way to test for specific antibodies, Richardson explained, using the ELISA test—the same process used in home pregnancy tests.
Now, Morrison asked about Mike’s blood serum samples, which Richardson had tested. “And were you able to determine from the testing whether or not there was the presence of specific antibodies that reacted to ricin?”
“Yes, I was able to make the determination.”
“And were they present?”
“Yes, they were.”
Not only were antibodies to ricin present in Mike’s blood serum, Richardson testified, they were present in such large quantities two months after the last episode of illness that he felt certain Mike had had “multiple exposures” to ricin. In lay terms, Richardson had just testified that, deliberately or accidentally, Mike had been fed ricin—not once but two or three times. Or more.
Moriarty rose to cross-examine, being deliberately folksy even though, for now, there was no jury listening. “Doctor,” he said, “there are some in here that think I’m not as smart as you. But be that as it may, I’m going to try my best.”
And try he did. Moriarty had boned up on ricin and the ELISA test. He had researched articles on ricin with long, esoteric titles and he had also found on the Internet a “book” called The Big Book of Mischief, which seemed to have some relevance to this case—a rabbit, perhaps, for the defense to pull out of its hat later. Moriarty did an admirable job of cross-examining Richardson, but he could not shake the scientist’s conviction that the antibodies in Mike’s blood proved he had been poisoned with castor beans several times.

With the tedious—but vital—scientific testimony on ricin antibodies out of the way, Morrison moved on to the night of October 23–24. Miriam Russell, the dispatcher from the Prairie Village Police Department, was first. It was Russell whose experience and quick thinking had resulted in the immediate dispatch of officers to Canterbury Court.
A hushed courtroom listened to a tape of the call Russell had taken at 12:21 on the morning of October 24. There were unidentifiable background noises and the sound of someone breathing into the phone, a ragged, panicky breathing. Then the line went dead. Either someone had hung up the phone, or the lines had been severed.
The “someone” had been Lissa, calling from her bedroom phone as black smoke oozed through her walls and around her door.
Steve Hunter was next. A field sergeant in charge of several patrol units in his sector, he was a trim man, well muscled, with a thick head of light brown hair. He had been the first officer on the scene of the fire, and memories of that night flickered across his face as he told how he had tried in vain to find Tim and Kelly and get them out of the burning house.
In clipped phrases, Hunter described for Morrison his first meeting with Debora and Lissa. “The juvenile was very frantic, sort of jumping up and down and screaming toward me that her brother and sister were inside the house trapped. ‘Please don’t let them die!’”
“Did she say that more than once?”
“She said, I believe, twice, ‘Please save them! Please don’t let them die!’”
“What was the other person doing?”
“Standing there. Did not make any comments. Did not say anything to me.”
“Is that other person here today?”
“Yes, she is.” Hunter pointed to Debora Green. “The second female at the defense table, in the white flowered top.”
“So what did you do then?”
“The juvenile said that her sister was in the rear upstairs bedroom. I also advised the dispatcher that we did have people trapped in the house.”
“All right. Did you know where Mom was—the mother of this girl?”
“No, I did not. . . . I asked, ‘Where’s Mom?’ And the defendant said, ‘Well, I’m Mom.’”
“Is that all she said?”
“Yes.”
“What was her demeanor like?”
“If I can describe it best,” Hunter replied, “about the same demeanor as I’m looking at her right now. Very unassuming. Very calm. Very cool.”
Staring back at the officer who had tried so hard to save her children, Debora was very calm and very cool.
Hunter told Judge Ruddick that he had tried to get into the house again and again, only to find all the doors blocked. “The fire was growing immensely, faster moving than I’ve ever seen a house fire.”
“Could you hear anybody at that point inside the house?” Morrison asked.
“No, I could not.”
Over the fire’s roar, it would have been difficult to hear voices calling for help. Hunter estimated that he and his men reached the scene about five minutes before the fire units began to arrive.
“Did you talk to a neighbor, John Forman?”
“It was later on in the morning—approximately seven o’clock that morning.”
“Did he give you something?”
“He gave me a typewritten letter, and Dr. Forman advised that he had found it in his yard.”
Hunter told Dennis Moore during cross-examination that he had remained at the
fire scene until sometime after noon—twelve hours later—when two bodies were removed from the burned house.
The defense had demanded the “field notes” of the officers who had been present at the fire scene, but that issue was put off until further proceedings. Now, Moore questioned Hunter closely about what he might have said to other officers at the scene. “You were, in fact, interviewed by members of the Metro Squad on October twenty-sixth?”
“Yes.”
“How did you describe Debora Green when you were talking to the officers of the Metro Squad that interviewed you?”
“Well, since I don’t have any notes to refer back to, to the best of my recollection as to how I testified: her demeanor was very calm, cool, and collected.”
“Did you say to Officers Boyer and Perry that she had a look of indifference on her face?”
“That may be the word I used to describe her.”
“Did you also say that she had a ‘smug look on her face’ and an expression like, ‘You’re not going in there. You’re not going to save anybody’?”
“That may be, yes.”
Hunter said he had not spoken to Dr. Mary Forman, except to say hello. The Formans had allowed him to use their bathroom. After he spoke to the Metro Squad, he had had no more input into the investigation.
Dr. John Forman, a thoracic surgeon—a heart and chest surgeon—took the stand next. He was a well-built man with high cheekbones and short hair. He looked young, although he had graduated from medical school seventeen years earlier. He also looked as though he would have preferred to be anywhere but on the witness stand in this hearing.
In response to Morrison’s questions, John Forman recounted how his eleven-year-old son found a letter in their yard while he was raking leaves. The boy had been confused by a word on the page he found: “adultery.”
“And I asked him where he’d found the letter and he took me outside and we found a second page and they seemed to go together.”
