Blake calls Dr. Erik Christensen to the stand. He is the Chief Medical Examiner for the State of Utah.
Christensen explains his background in forensic pathology.
Christensen performs autopsies and has worked as a forensic pathologist in Virginia and South Carolina before moving to Utah.
Blake asks Christensen the process in which autopsies are performed in Utah. Thomas objects and says Utah procedures don't matter in this case. Blake responds that Christensen performed an autopsy in this case (Tammy Daybell). Boyce overrules the objection.
Utah does not have the coroner system. In Idaho, each county has a coroner to investigate cause of death. Medical examiners are used in Utah.
Christensen has performed around 7,200 autopsies in his career.
Christensen performed Tammy Daybell's autopsy. He says his office was contacted in Nov. 2019 by the Fremont County Sheriff's Office with questions about exhuming a body and having an autopsy done. Christensen was there when Tammy was exhumed and her body was loaded into a vehicle
He then went to his office and was there when the body arrived.
Christensen says it's routine for him or someone in his office to attend an exhumation when they are needed.
Christensen obtained Tammy's medical records before she was exhumed. Over the course of his career, he says he's been involved in "a dozen or two" exhumations. They are not common.
Blake asks if a body is exhumed does it make it more difficult to do an autopsy? Christensen says most of the time, the deceased person has been embalmed so it makes their tissues stiffer but that also helps preserves the organs, tissues, etc.
Christensen says Tammy's casket was dry and the conditions were fairly good when it came time to do the autopsy.
Sketches from this morning
Blake asks Christensen to describe how an autopsy is done. He explains that the entire body is checked over, fluids are taken, body parts are examined - it's a very thorough exam.
Samples are collected during an autopsy to assess under a microscope. Bruises, cuts and scrapes are also examined under a microscope because they give information about how long the injury has been on a body, Christensen says.
Christensen says Tammy's cause of death was asphyxia and her manner of death was homicide.
Blake asks Christensen what asphyxia means. "It's simply a process by which a person is deprived of oxygen. They're not allowed to take in sufficient oxygen for their life to continue."
Christensen says there were no outward visible bruises or injuries that showed she died of those injuries.
Christensen explains there was no indication that Tammy had a history of seizures and her brain was totally normal.
"There are a number of ways people can be asphyxiated with. Suffocation, neck compression, anything that impairs someone's ability to breathe normally," Christensen says. When someone stops breathing, they lose consciousness but their heart can continue to beat for a time.
Christensen says they looked at pesticides and other potential drugs. There was nothing in her system that played a role in her death.
There were bruises on Tammy's arms that happened in the hours around the type of her death, Christensen says. "They are consistent with someone being restrained and would be consistent with asphyxia being cause of death as well."
Blake asks Christensen about seizures and whether he has conducted autopsies of people with seizure issues. He says yes. There are often tongue injuries and bowel or bladder issues. Tammy had neither.
Christensen says it would be uncommon for a 49-year-old woman like Tammy to start developing seizures.
Nothing in Tammy's medical records showed she had seizure or heart issues, Christensen says.
Christensen says testing was done for intoxicants. Blake asks if this means poisons. He says yes, it includes that.
They tested for hundreds of intoxicants, illicit drugs and over-the-counter medications along with insecticides, cyanide, heavy metals, phosphate positions, nerve agents - none of those were found.
"We did a lot more testing in this case than we normally would and everything came back negative except the medication she was prescribed," Christensen says, adding that it's one of the most extensive autopsies he's been involved in.
The optimal substance to test is blood. Because Tammy had been embalmed, liver samples were sent to be tested. Christensen looks directly at the jury while explaining all of this.
"There was not a toxicological explanation for her death," Christensen says.
Boyce announces we are taking an afternoon break until 2:30 p.m.
Boyce is back on the bench and jurors are being brought in.
Blake asks if Tammy's organs appeared normal. Christensen says for the most part, yes...but there was fluid in the lungs & a frothy dry foam in her airways. Blake asks to show a photo to the courtroom. It's a closeup of Tammy's face that shows the pink foam coming from her mouth
The pink foam is a manifestation of pulmonary edema, Christensen says. He has conducted other autopsies where this foam has been present. Pulmonary edema is a physical manifestation of an underlying process.
"We most commonly see this kind of setting in opioid intoxication and can be seen in drownings, heart failure, any number of things that can cause pulmonary edema."
"Whatever caused the pulmonary edema would be the cause of death," Christensen explains. He says this played a part in him determining asphyxia was the cause of death.
Blake gives Christensen a paper to mark where he located the bruises on Tammy's body. Boyce asks what he is using to mark the sheet. Christensen responds that it's a blue pen.
Christensen has finished marking the exhibit. Blake asks the diagrams be shown to the court.
The exhibits are now being shown on the screen. We see a diagram of the front of Tammy's body.
Christensen marked three blue dots representing bruises on Tammy's upper right arm, a blue dot on the lower right arm, a mark on the chest above her left breast and a blue dot on the left arm over the bicep.
On the diagram of the back, there are bruises on the back of the right upper arm, one on the lower part of the arm and one on the left arm.
Blake now wants to show close-up photos of the bruises found on Tammy's body.
The first photo shows Tammy's left upper chest with a bruise. We are not shown the image but Christensen describes it. The next picture shows a closer view of the bruise. We see this image. It is black/dark blue.
The following photo will not be shown but it's her upper arm with bruises on her right bicep. The following photo is a close-up of the bruise and we see the picture. We now see an image of Tammy's right forearm with bruises on it.
The next picture is the front side of Tammy's right forearm with a bruise. Other photos show more bruising on Tammy's arms.
Christensen says it's more than likely the bruises were on Tammy's body before she died because once circulation stops, it's much harder to cause a hemmorage.
Christensen says the injuries on Tammy's body occurred around the time of death.
More photos are shown of the bruising on Tammy's body. Some of the photos are shown to the entire courtroom, others are not. Christensen explains the injuries.
Christensen noticed signs of lividity. This is when the blood pools at the lowest point of a person's body following their death. Over time, the lividly becomes "fixed" & the blood will no longer be moveable. Christensen says on Tammy's body, there was fixed lividity on her back.
Blake asks Christensen is lividity permits him to determine a cause of death. He says no. Blake asks what rigor mortis is. This is the stiffening of the joints and muscles a few hours after death.
Blake asks Christensen if a time of death can be determined off rigor mortis. He says it can be looked at and helps but the longer a person has been dead, the wider the time of death estimates would be.
Christensen was not present the day Tammy died and says he relies on external information to help determine when a person dies. Christensen says based on what Chad said about Tammy being cold and stiff at 6 a.m., it's likely she died a couple hours earlier.
Christensen says he looked at other causes of death and did not find them to be likely in Tammy's death. He again stresses the cause of death was asphyxia and the manner of death was homicide. Blake has no further questions for the medical examiner.
The monitors will now be arranged to the jury, attorneys and judge can see the graphic images of Tammy's bruises. The audience will not be able to see them.
Blake shows the images as Christensen describes them.
Lori is not looking at the monitor that shows the bruises.
The photos have all been shown to the jury. Black has nothing further. Defense attorneys will cross-examine starting tomorrow.
Court is adjourned. Some big developments today.
Two more sketches from today. The one with Dr. Christensen shows blue marks he made on a diagram showing bruises he observed on Tammy Daybell's body during the autopsy.
