Chapter 7 - THE PRESERVED BLOOD
The blood tube had been opened in the pathology laboratory eighteen months earlier.
That fact sounded sinister until Dr. Sanjay Patel explained that samples may be opened for repeat testing, transfers, inventory, or quality review.
The problem was documentation.
The chain-of-custody log contained a gap.
At 2:14 a.m. after Emily died, the tube was sealed and placed into refrigerated storage.
At 8:32 a.m., a laboratory employee entered a note:
ADDITIONAL ALIQUOT PREPARED PER PHYSICIAN REQUEST.
No physician request appeared in the chart.
The employee who entered the note, Teresa Moss, no longer worked at the hospital.
Nolan located her in Knoxville.
Teresa remembered the case because a woman identifying herself as a family nurse arrived with documents authorizing release of a small serum portion for “specialty cardiac testing.”
Hospital policy did not allow a family representative to remove specimens that way.
Teresa said a supervising pathologist approved it by phone.
The pathologist, Dr. Leonard Ames, denied receiving the call.
The serum portion was never returned.
“Was the woman Patricia?” Nolan asked.
Teresa viewed a properly administered photo array.
She selected no one.
She said the woman had dark hair, glasses, and a medical badge.
Patricia had blond hair then, though she often wore dark wigs during volunteer theater events.
That did not identify her.
The retained blood showed elevated digoxin.
The vitreous-fluid result was lower but still concerning.
Liver tissue contained the drug.
Dr. Helen Wu, an independent forensic toxicologist, explained the limitations at a case conference.
“Postmortem concentrations can vary. Digoxin may redistribute. Blood levels alone should not be treated as a perfect measure of the concentration before death.”
“Could the amount have killed her?” I asked.
“It is within a range reported in fatal intoxications. It can also overlap with some therapeutic or postmortem circumstances.”
“She had no prescription.”
“That strengthens concern.”
“She had symptoms.”
“Nausea, visual disturbance, weakness, and arrhythmia are compatible with digoxin toxicity. They are not unique to it.”
“Then what would you call this?”
“Evidence consistent with unprescribed digoxin exposure requiring investigation.”
Every careful word felt like resistance.
Later, I understood that careful words were the only kind that survived a courtroom.
Emily’s emergency records contained another clue.
Her potassium level was elevated when she arrived at the hospital. Severe acute digoxin toxicity can be associated with hyperkalemia, though other causes exist, including resuscitation, cell injury, and sampling issues.
Her heart rhythm displayed patterns that a cardiology expert said could be consistent with digoxin effect.
No antidote specific to digoxin toxicity had been given because no one knew to suspect it.
Would the antidote have saved her?
No physician could promise that.
The medical examiner amended the cause of death from likely natural arrhythmic death to undetermined pending investigation.
Not homicide.
Not yet.
Patricia’s defense hired its own toxicologist, who emphasized the chain-of-custody gap and postmortem uncertainty. He suggested contamination or analytical error should be excluded.
The samples were retested at another accredited laboratory.
Digoxin appeared again.
The concentration differed, as expected between methods and specimens, but the presence remained.
Patricia’s lawyer announced that Emily may have taken the drug intentionally.
He released selected diary messages where Emily described exhaustion and wrote, “Sometimes I want the noise to stop.”
The full diary contained the next sentence:
Not my life. The lies around it.
Grief had taught me how easily one line could replace a person.
Investigators searched Emily’s purchase history, browsing records, pharmacy databases, and communications for evidence that she obtained digoxin.
They found none.
Patricia possessed the medication.
Opportunity existed.
Motive through financial exposure existed.
A direct act remained unproven.
Then the forensic examiner recovered deleted audio from Patricia’s shattered phone.
The device had continued recording notes automatically after striking the sink.
Most of the file contained running water, officers’ voices, and movement.
Before the phone broke, it captured Patricia in the laundry room.
My voice asked, “What did you do to her?”
Patricia answered too quietly for me to hear at the time.
Audio enhancement recovered the words.
“I gave her what Evan bought.”
My brother’s name entered Emily’s death investigation publicly the next morning.
Evan called me seventeen times.
I answered the eighteenth.
“She is lying.”
“Did you buy digoxin?”
“No.”
“Did you buy anything for her?”
“Not medicine.”
“What did you buy?”
“A company.”
“What company?”
“Lantern.”
The shell vendor had not been Patricia’s creation.
Evan had purchased it two years before Emily died to route payments outside ordinary company reporting.
He transferred control to Patricia after the nonprofit began using it.
“Why?”
“To move money quickly.”
“For what?”
“Project expenses. Personal expenses. Things I did not want the board questioning.”
“Emily discovered it.”
“Yes.”
“And Patricia said you both would lose everything.”
“Yes.”
“What did you mean when you told Patricia you would speak to Emily?”
“I meant exactly that.”
“Did you go to the house?”
“At six fifty.”
“Did you bring anything?”
Evan was silent.
“Answer me.”
“A package.”
“What package?”
“Patricia asked me to pick up her mother’s belongings from a storage facility. She said she could not get there before closing.”
“What was inside?”
“I did not look.”
“Was it a pharmacy bag?”
“It was a cardboard box.”
“Did you give it to Patricia?”
“Yes.”
Evan’s lawyer took the phone and ended the call.
Storage records showed Evan collected a sealed box belonging to Margaret Lane’s estate at 5:38 p.m.
An inventory form listed clothing, photographs, jewelry, and medication.
Digoxin was specifically named.
Evan had carried the drug into my house.
Whether he knew what Patricia intended remained unresolved.
That night, someone broke into the storage facility.
The original inventory binder disappeared.
