Chapter 9 - SAMPLE 481
Robert stared at the two reports side by side.
“This is the right question.”
We were at our kitchen table again.
Ethan was at school.
Michael had taken the morning off.
“What question?” he asked.
Robert tapped Patricia's report.
“Not whether this result is false. Whether the identities attached to the samples are false.”
I pointed to the codes.
418 was labeled Ethan.
481 was labeled Michael.
“We know at least one is wrong.”
Robert nodded.
“Possibly both.”
Michael leaned back.
“How do we figure out which?”
The laboratory wouldn't release genetic profiles or customer information to us simply because we asked.
Nor should it.
But the report itself contained relationship statistics.
Robert studied them.
“Don't try to reverse-engineer this yourselves.”
“We aren't,” I said.
“I mean it. Get professionals involved if you intend to challenge anything formally.”
He was right.
We sent both reports to Laura.
She recommended preserving them and making no accusations we couldn't prove.
Then Michael remembered something.
“My razor.”
I looked at him.
“What?”
“At Mom's house.”
He explained.
Two months earlier, we'd stayed overnight after a family dinner because a storm made driving home difficult.
Michael had shaved the next morning using a disposable razor Patricia kept for guests.
He threw it in the bathroom trash.
“Could she get DNA from that?”
“Possibly,” Robert said, “but don't assume that's what happened.”
Michael looked disgusted.
“I can't believe we're discussing my mother digging through trash for DNA.”
I almost pointed out that she'd given our son trash as a birthday gift.
Instead, I asked the useful question.
“Did she ever say how she got your sample?”
“No.”
Her words came back to me.
I had access to what I needed.
Not I swabbed Michael.
Not Michael gave me a sample.
Access.
I wrote the phrase down.
That evening Michael called Patricia.
This time, I sat beside him.
Speakerphone.
“Where did you get the sample you labeled as mine?”
Patricia was silent.
Then:
“You're still letting her do this?”
“Answer me.”
“I had something of yours.”
“What?”
“Something personal.”
“What?”
“You throw things away constantly.”
Michael closed his eyes.
“The razor?”
Another silence.
Then Patricia said, “You have your answer.”
She hung up.
Michael exhaled.
“So Sample 481 was mine.”
“No.”
He looked at me.
“She implied it.”
“She didn't confirm the sample code.”
Robert had taught me something important over the previous week.
Don't turn implication into evidence simply because it fits.
Still, Patricia had now admitted obtaining biological material from something Michael discarded.
That was new.
And ugly.
Laura later explained that testing an item without verified collection could create uncertainty about contamination and identity.
But the central problem remained.
If Patricia genuinely used Michael's discarded item, then perhaps Ethan's sample was the false one.
Unless Patricia was lying about the item too.
For the first time, I understood how difficult deliberate uncertainty could be to untangle.

Patricia had admitted using biological material taken from something Michael discarded, but she still hadn't established that it became Sample 481.
In Chapter 10, one ordinary photograph from the afternoon she swabbed Ethan showed me that another person had been in Patricia's kitchen—and suddenly Sample 418 had a second possible source.
