Cline trial: Defense calls expert witness

Send a link to a friend

[September 21, 2011]  After taking a long weekend, the jury returned to the courtroom Tuesday morning to continue hearing testimony in the murder case against Ty Cline. 

Cline is being charged in the death of 2-year-old Lucas Alberts in 2009. 

On Friday afternoon, the prosecution rested their case, but because the first witness for the defense was not to be available on Monday, attorneys Jay Elmore and Jeff Page did not begin questioning for the defense until Tuesday. 

Before the jury was called into the room at the beginning of the day, Elmore made a motion to the judge for a "directed verdict." By definition a directed verdict is "a procedural device whereby the decision in a case is taken out of the hands of the jury by the judge." Judge Thomas Harris denied the motion, saying he believed the jury had seen sufficient evidence to make an informed decision. 

The first witness to be called to the stand was Dr. Mark Shuman, an assistant medical examiner from Miami-Dade County, Fla. Shuman indicated he was a forensic pathologist with experience in investigating sudden, unexpected death. 

The first several minutes of questioning by attorney Page involved establishing Shuman as an expert witness by going through his extensive resume. Shuman was asked if he had testified as an expert in other cases and he confirmed that he had. When asked how many, he said approximately 40. Asked how many times he'd testified for the prosecution of a case he said 25, leaving 15 times he has, as in this case, testified for the defense. 

Page asked, "Did we (the defense) contact you?" Shuman answered, "Yes." Page: "Did we ask for your opinion?" Shuman answered, "Yes." Page: "Did you prepare a report?" Again Shuman answered that he did. 

Page asked Shuman how he was able to do this, and Shuman explained that he had requested certain materials from the defense for his review. Page asked what those materials were, and Shuman answered that he had requested most everything at the attorneys' disposal. He read through a list that included police reports, autopsy reports, reports from the Department of Child and Family Services, hundreds of photographs, plus much more. 

Page asked Shuman to confirm he was not directly involved in this case and had no firsthand knowledge of what had happened, and Shuman did. 

Page asked if Shuman had requested pictures of Ty Cline's hand and pictures of the rat cage Lucas Alberts allegedly fell on. Shuman said that he did, and Page asked why. 

Shuman explained that he used the photos to overlay on existing pictures of the bruising on Alberts' cheek so that he could determine if either matched. 

Asked how such matching worked, Shuman said he used computer software that calculated the pixels in 1 centimeter in each picture, then adjusted the size of the pictures until the pixels were the same in each. He then made the pictures of the hand and rat cage semi-transparent and superimposed them on the marks on Alberts face. 

The photos taken were of Cline's left hand lying flat with his fingers close together. Asked why, Shuman said the fingers would have had to have been held closely together in order to make the straight-line marks on the child face. 

Misc

Through a series of slides, Shuman showed the overlay of the hand on the face with the little finger at top and the index finger at the lower end of the jaw.  

Page noted pale spaces between the lines on the boy's face and recalled that Dr. Scott Denton performed the autopsy and testified for the defense that the pale spots were made by pressure from the fingers. He asked if Shuman agreed, and Shuman said he did not because the fingers were too wide to go with the pale spots. 

Page noted a rounding of the white spot closest to Alberts' ear and said Denton had said that was the tip or end of Cline's finger. He asked if there were any additional rounded-off spots Shuman saw. Shuman indicated that there was a very similar rounding on the other end of the same area, closer to the mouth. 

Page talked about the separate planes of the face and Denton's argument that a rat cage with a single plane could not have injured the boy on the side of the face and below the chin. Page asked Shuman if he saw any injury below the chin. Shuman said he did not. 

Page finally asked, "In your opinion, are the marks on Lucas Alberts face from a hand or fingers?" Shuman said, "It is possible." 

Moving to the rat cage, Page asked about the comparisons Shuman had done there. Again Shuman went through the process of creating a superimposed picture. 

Page asked if the wires of the cage matched the marks on the boy's face, and Shuman confirmed that they did. 

Page then asked which was the most likely scenario, the rat cage or the hand, and Shuman said he could not make a determination on the injuries alone because there were other factors involved. 

In other testimony Shuman said he was aware of damage to the throat, but in Denton's report the same injury had been reported with two different locations. The difference in the locations was one was under the chin on the left side, and the other location, mentioned by medical terms, was lower down on the throat but only slightly. Shuman began giving his opinion on which area Denton actually meant, and Wright objected, saying Shuman couldn't actually know that. 

Page asked Shuman if the injury to the throat area could have been caused by something or someone other than Cline or the rat cage. Shuman said it was an injury that can occur during lifesaving measures such as intubations. 

Shuman also had a difference of opinion from Denton in how the retinal and optical bleeding may have come about in Alberts and substantiated his opinion with various publications on the subject from other considered experts. 

Moving on to the topics of "lucid period" and "symptom-free period," Page questioned Shuman, asking if Alberts could have been lucid after his head injury. Shuman said, "Yes, he could have." Page asked if he could have been symptom-free. Shuman: "Yes, he could have." Page asked, "For up to 72 hours?" Again Shuman confirmed that he could have been.

Page asked if Shuman agreed with a study statement that said infants and toddlers lose consciousness less frequently than adults, and Shuman said he did. 

Quoting from the paper written by Dr. Denton, Page asked if Shuman agreed with the statement "It is a widely held dogma that the person with the child when it loses consciousness is the perpetrator." Shuman said, "Yes, I agree it is a dogma." 

Shuman then began talking about a syndrome called "talk, deteriorate and/or die." He began talking about published works that had not been included in the disclosure list for the defense, and Wright objected. 

In discussion, the defense said they didn't know about this report, but if it was footnoted in other reports, it should be allowed in. Judge Harris disagreed, saying that if attorneys had to research every footnote, it would be too much. He concluded by saying, "If it is worthy of testimony, it is worthy of disclosure." He upheld Wright's objection, and the topic moved away from that study.  

When Wright began his cross-examination of the witness, the first question regarded payment for service. He asked Shuman if he was being paid, and Shuman said he was. Wright asked how much, and Shuman indicated $300 per hour. After inquiring about the time spent to travel to Lincoln, Wright surmised that the cost for Shuman's services was approximately $10,000, and Shuman confirmed the estimated amount. 

Wright asked if Shuman had ever testified for the defense when he agreed with the state or prosecution. Shuman indicated that he had, but added: "Generally if I agree with the state, I'm not called to testify (by the defense)." 

Wright began by going back through Shuman's testimony on "lucid" and "symptom-free." Wright asked if Shuman's report was based on his own opinion and if he was asked to address whether or not Alberts could have been lucid and symptom-free. Shuman confirmed that he was. Wright asked if Alberts could have possibly been symptom-free for 72 hours. Shuman said he could have, but he didn't want to restrict his opinion in the matter. Wright then asked, "So he could have had immediate symptoms?" and Shuman said "yes." 

Moving on to the clinical history behind Alberts' death, Wright asked Shuman to confirm that the history collected in 2009 said Alberts was healthy when he was left with Cline and that he had no injuries at that time. 

Wright said, "If you look at the totality of the circumstances, look at the injuries and clinical history, Denton's opinion that symptoms would have been immediate is correct?" Shuman said, "No, we don't know when it occurred because there is no history for the impact to the back of the head. The rat cage injury was secondary." 

Wright asked about Shuman's report, which said symptoms were more likely to have occurred closer to the injury. He asked if statistics showed that in more injuries the lucid or symptom-free period is less than 72 hours, more like 24. Shuman confirmed. 

Wright then asked, "Is it more likely in this case?" Shuman: "No, you can't apply probabilities to one person." 

Wright commented that statistics were equal to probabilities and Shuman agreed. Wright then said Shuman had referenced a study based on statistics. "You gave probabilities to that, but you don't want to give probability now. Correct?"  

Shuman replied, "No, in this case I can't say." 

Wright asked, "You have to look at the child plus the history?" Shuman confirmed. 

Wright then said, "Dr. Denton said symptoms were likely immediate." He asked if Shuman agreed, and Shuman said, "I don't know, I wasn't here." 

Wright moved on later to discussions about Cline's hand and the rat cage. He asked specifically why the left hand had been used as a comparison, and Shuman said that was the photo he was sent. Wright observed that using the left hand seemed awkward, and Shuman agreed. 

Wright also asked about the cross wiring on the rat cage where it was dented and wondered why it was not in the comparison. Shuman said it was, but at the edge of the marks.

Wright then said Shuman had made an assumption in the comparison. Shuman said he had not and asked what assumption it was. Wright said, "You assumed the perpendicular lines would not be in the middle." 

Wright later commented, "You did nothing to show the perpendicular lines because there are no signs of them (on the face). Shuman countered, saying he had not assumed anything, he just had to match the lines with the picture. 

Wright touched on several other areas of the original autopsy versus Shuman's report, including the retinal and optical bleeding found 

Before closing his cross-examination, Wright came back to the money Shuman is being paid. He said that Shuman was being paid to testify, paid for his opinion. Shuman responded, "I'm not getting paid for my opinion, I'm getting paid to be here."
