Final Analysis - Catherine Crier [61]
After he analyzed each of the individual stab wounds, Dr. Peterson determined that the wound where the knife penetrated the right lung lobe and the one just below it where the knife entered the sac around the heart had caused the most internal bleeding and “could have been lethal.” He classified the remaining twenty-two stab wounds as “relatively superficial,” noting that they varied in severity.
In addition to the wounds from the knife, there were also three different “blunt force injuries” on Felix’s body. There was an abrasion on one knee and a bruise in the middle of his back, just below one of the five deep stab wounds. Peterson ruled that neither of those was particularly significant in terms of death. A third injury, however, located three inches above the right ear canal and measuring one and a half inches long by one-eighth inch wide, indicated a “relatively good impact” to the head. There was no associated brain injury, but it appeared the bruise was consistent with “being hit with something,” the pathologist said. Dr. Peterson theorized that the injury to the head might have incapacitated Polk and limited his ability to fight back.
“If the injury had occurred at the onset of the fight, it’s possible his struggles were less effective,” he theorized. “In other words, Felix could have been stunned, or partially stunned, by getting hit in the head and less able to defend himself in any effective way.” While Dr. Peterson could not determine what caused the three blunt force injuries, he believed it was “from a blow” rather than a fall. Nevertheless, he could not find any pattern on the skin, such as a shoe tread or hammer impression that could help police identify the instrument that was used.
Interestingly, the forensic examination revealed that Felix Polk had high blood pressure and suffered from coronary heart disease. The left main coronary artery and the left anterior descending artery that provides blood to the left chamber were both blocked; a condition that “causes a lot of problems, including sudden death,” Dr. Peterson noted in his testimony to the Grand Jury in August 2003. Meanwhile, Felix’s heart weighed twice that of a normal heart for someone of his size and age. “It was a significantly sick heart,” Dr. Peterson said. “It didn’t cause his death, but it’s likely a factor…. He had heart disease going into the attack, and as emotions ran high as [he was] being killed, it wouldn’t have been unusual for him to have heart symptoms,” he observed.
Later, when asked by a member of the Grand Jury why Felix Polk did not scream for help, Dr. Peterson pointed to three factors: Felix’s heart disease, the blunt force trauma to the head, and the two quick and deep chest wounds. “Faced with that kind of attack, I think, I personally would have spent more time trying to defend myself as opposed to calling out,” Dr. Peterson said. “Again, he was relatively stunned from the blow to the head…confused, and simply not able to.”
In the days following the Orinda murder, journalists reported that Felix Polk was brutally stabbed—conjuring up images of Anthony Perkins in the movie Psycho. At a press conference at Orinda police headquarters, Police Chief Dan Lawrence allayed fears that a killer was on the loose in the community. He assured residents of the quiet East Bay community that the homicide at the Polk residence was “not a random murder,” but a “domestic-violence issue.” In the weeks prior to the murder, officers were summoned to the Polk home in response to domestic disputes, he said. In addition, evidence found during a search of the residence indicated the victim’s wife played a role in the crime, he said.
“These things can happen time and time again anywhere,” Lawrence said.
Though there was an everyday nature to the situation, the public’s response to the savage death and bizarre history
