“Yes sir.”
“What did you find on the cans?”
“Saliva, apparently from the person who drank the beer.”
“Where was the saliva found?”
“Around the opening in the can that you drink from.”
“And what else did you find around this opening?”
“We found lip prints.”
“And just what are lip prints?”
“Just as each individual has a set of unique fingerprints, each person’s lips have patterns of ridges, grooves, and wrinkles that are specific to that person. Distinct and intact lip prints were taken from the beer cans.”
“Is this a scientifically accurate method?”
“Most definitely.”
“And were those prints identified?”
Saperstein folded his hands on his lap. “They were matched against those obtained from another lip print sample.”
Denton took a step forward toward Saperstein, drawing the jurors’ attention to his witness. “And what was your conclusion as to whose lip prints were present on the beer cans?”
“The lip prints matched those of Brittany Harding.”
A slight murmur rumbled from the spectator seats in the middle of the courtroom. Calvino looked up and restored order with his stare.
“Those of Brittany Harding,” repeated Denton. “Not Phillip Madison. Brittany Harding. Are you sure?”
“Quite sure.”
“Were there any other tests that were performed on the saliva that was on the beer cans?”
“Yes.”
“What kind of tests were those?”
“We performed a blood group study and a DNA analysis.”
“Relative to the blood group, what blood type was found in the saliva?”
“AB,” Saperstein said.
“Did you test Dr. Madison’s blood type?”
“We did. It was type O.”
“And Brittany Harding’s?”
“AB.”
Denton raised his eyebrows in mock surprise. “The defendant was AB, and the type found on the beer cans was AB?” he asked, reinforcing the fact, rubbing hand lotion into the jury’s collective skin and watching it soak in.
Saperstein said, “Yes.”
“What percent of the world population is type AB?”
“AB is the rarest blood group that exists. Less than four percent of the population has it.”
“What about type O? Just to give us a basis of comparison.”
“Approximately forty-five percent of the population is type O.”
“So AB is quite rare.”
“Yes.”
“You also said that you performed DNA testing on this saliva,” Denton reminded him, receiving an affirmative nod from Saperstein. “I’m not going to go into the specifics of the testing procedure with you, because we have a witness who’ll be testifying in that regard. But can you please tell the court whose DNA was found in the saliva?”
“That of Brittany Harding.”
Another mumble from the courtroom.
“Quiet, please,” Calvino ordered.
“So let me get this straight, Mr. Saperstein,” Denton said, placing a hand on his chin. “You testified earlier that the vehicle used to cause the deaths of the two decedents was the Mercedes owned by Dr. Phillip Madison. And now you’re saying that the beer cans which were found in the rear of that car did not in fact bear any identification relative to Dr. Madison, but in fact contained lip prints and saliva that were consistent with Brittany Harding’s-”
“Objection,” Warwick said, standing. “Is there a question here? Or is counsel merely summarizing the witness’s testimony, putting words into-”
“I’m not putting words-”
Calvino banged his gavel. “Let’s keep this civil, please. Unless you have something constructive to offer, allow me to make my ruling on the objection, Mr. Denton.”
“Sorry, Your Honor.”
“Objection sustained. Mr. Denton, ask a question or dismiss your witness.”
Denton faced his witness. “Mr. Saperstein, what certainty would you give the fact that the lip prints belong to Brittany Harding?”
“Ninety-five percent.”
“And what’s the chance that the DNA profile you obtained could come from someone else other than the defendant?”
“I would say that there is an extremely low probability.”
“Can you put that into numbers, Mr. Saperstein?”
Saperstein pursed his lips. “Based upon the testing method used, there is only a one-in-fifty-thousand chance that it is not Brittany Harding’s.”
“Objection. This gentleman is not listed as an expert on DNA by the prosecution.”
“He has a point there, Mr. Denton,” Calvino said.
“Your Honor, this gentleman is a senior criminalist who is trained in DNA analysis. I chose to designate a different witness as our DNA expert in order to corroborate the findings of Mr. Saperstein.”
“I didn’t hear you qualify Mr. Saperstein as an expert on DNA analysis,” Calvino said.
“Very well, Your Honor, I shall do so.”
“Mr. Warwick?” Calvino asked.
“I withdraw my objection pending Mr. Denton’s qualification.”
Denton stepped forward. “Mr. Saperstein, what is your training on DNA analysis?”
“I attended several course offerings at University of California at Berkeley and received certification in DNA handling and analysis nearly ten years ago.”
“And in how many cases have you performed DNA analysis? Approximately.”
“Between three and four hundred, I would estimate.”
“Your Honor, I submit Mt. Saperstein to the court as an expert in DNA analysis.”
“Mr. Warwick, do you have any objections?”
Warwick frowned. “No, Your Honor.”
“Very well, then,” Denton said. “Mr. Saperstein, you were quoting us the probability that another person could have the same DNA as that of Brittany Harding.”
“Yes. There is a one-in-fifty-thousand chance that another person’s DNA would match Miss Harding’s DNA, according to the method of analysis we used.”
“One in fifty thousand. And we already know that the only other suspect who ever existed in this case-Phillip Madison-his DNA does not match that found on the cans. Is that correct?”
“Yes. We tested Dr. Madison’s DNA, and the pattern’s not even close.”
“Thank you, Mr. Saperstein,” Denton said as he walked back toward the prosecutor’s table; he nodded to Warwick. “Your witness.”
“Mr. Saperstein,” Warwick said as buttoned his sport coat, “did you perform all of the tests on the evidence gathered at the crime scene?”
“No, I did not. I was ill with ulcerative colitis and-”
“Yes, sir, a simple yes or no would be sufficient. Did you perform the testing that was carried out on the lip
