in my mind, there is no doubt that she murdered Matthew," Dr. Sunny Eappen, the father, told CBS interviewer Bryant Gumbel on "Public Eye with Bryant Gumbel." "I think there's no doubt that what happened was not an accident," he said, discounting the defense argument that their almost 9-month-old son died in February from previous injuries. "I think the medical evidence (presented by the prosecution) has more than justified that." Jurors, now sequestered and under orders not to watch or read anything concerning the trial, have deliberated for two days without reaching a verdict in the case. Earlier on Wednesday, the jury asked to rehear testimony from the doctor who had operated on the child after he was brought into Boston's Children's Hospital. Their request prompted an argument between prosecution and defense lawyers over whether the specific part of the testimony requested or the entire testimony of the doctor should be reread to the jury. The jury must decide between three possible verdicts: guilty of first- or second-degree murder, or acquittal. Deliberations were set to resume on Thursday. During the trial, prosecutors portrayed Woodward, a 19-year-old from Chester, England, as so frustrated and angry that she violently shook the crying, colicky child and then slammed his head. On the CBS program, the mother said that although they had instructed Woodward to call 911 immediately if anything was amiss, she had to insist -- when Woodward called her at her office -- that she call for emergency assistance. The baby died five days later from severe brain injuries. The defense has contended that skull and wrist fractures occurred weeks earlier and that any slight trauma to the head might have caused a blood clot to rebleed and grow, causing great pressure on the brain and ultimately death. Debbie Eappen, a doctor like her husband, said the defense argument was "totally ridiculous... He was perfectly healthy." Speaking of Woodward, the mother said: "She once told me she didn't want to have children. Part of me really hopes she doesn't have that joy in her life."
