Chapter 13 - THE THIRD SIGNAL
Investigators returned to the camera system.
The equipment did not include a normal two-way speaker. However, the camera above Emily’s bedroom door had an audio output connection that Michael had modified.
A small wireless receiver inside the wall allowed sound to be transmitted from another device.
Someone could speak through the camera.
Thomas may have used the feature.
Michael may have configured it.
Emily believed Anna had spoken through it.
Digital records showed three late-night audio sessions during the month before the 911 call. The remote user connected through an anonymized service. The sessions were not recorded in the ordinary cloud archive.
The source could not immediately be identified.
Emily’s description required careful handling. Investigators did not repeatedly question her. Ava conducted one follow-up forensic interview after new evidence established that the audio feature existed.
“Tell me about the voice from the green light,” Ava said.
“It said my name.”
“What did you think when you heard it?”
“I thought it was Mommy first.”
“What made you think it was Anna?”
“She told me.”
“What did she tell you?”
“That she was Daddy’s sister. She said Daddy used to hide too.”
“Did she ask you questions about Daddy?”
“No.”
“What did she say to do?”
“Keep Mommy’s phone in Mr. Buttons. Call 911 if Daddy came after the blue blanket.”
Ava did not ask what “came after the blue blanket” meant.
Emily had already described enough for the investigative team to understand the sequence of her fear.
“Did the voice ever tell you what to say?”
“It said I could use my words.”
“Did it tell you to say snake?”
“No. Daddy used that word.”
The interview reduced the likelihood that Anna had coached the specific allegation. It did not prove the speaker was truly Anna.
Michael’s devices contained software capable of accessing the wall receiver. One laptop had been wiped hours after Thomas’s arrest.
Forensic specialists recovered fragments of chat logs.
A user identified as MM wrote:
The child called. Delete the seventeen.
Another user responded:
Already done.
The timestamp was 9:17 p.m.
Michael was at a restaurant with several people at that time. Receipts and surveillance showed him seated at a table.
But his phone was briefly taken outside by an unidentified person wearing a hooded coat.
The restaurant camera captured only the person’s back.
Michael claimed not to remember anyone taking the device.
His attorney suggested investigators had misread the footage.
Ortiz believed he was lying.
Belief was not enough.
Sarah’s recovered phone contained a photograph taken through her apartment window on the afternoon of her death.
Michael’s truck was parked across the street.
Beside it stood another vehicle registered to Evelyn.
Evelyn had admitted visiting.
The photograph did not show who arrived later or who remained.
A draft email on the phone was addressed to Julia.
I was wrong about one thing. Thomas did not put the first camera in the house. Michael did. Evelyn paid him. She said it was to protect Emily, but Anna says the family has always called watching protection.
The email ended mid-sentence.
At Thomas’s criminal case, defense experts challenged the digital evidence. They argued timestamps could shift, shared credentials weakened attribution, and file names did not prove who created content.
The prosecution commissioned independent verification rather than pretending the defense raised impossible questions.
Some evidence grew stronger under scrutiny.
Other evidence became less certain.
One external drive had been used by both Thomas and Michael.
A set of deleted clips could not be attributed confidently to either man.
The SLEEP STUDY folder, however, had been opened repeatedly through Thomas’s personal user profile. His biometric login had been used during several access events.
Thomas faced the possibility of a long sentence if convicted.
His attorney approached Porter about a negotiated resolution.
Thomas was willing to admit to offenses against Emily and waive certain trial rights.
In return, he wanted a sentencing recommendation below the maximum and protection against prosecution for Sarah’s death.
Porter refused the second condition.
“We do not trade immunity for a death we have not solved.”
Holloway said Thomas had information.
“Then he can provide it without guarantees.”
Thomas requested a proffer session—a controlled meeting in which he could describe potential information under negotiated terms that did not automatically grant immunity.
During the session, he admitted that Michael manipulated his workplace access record the night Sarah died.
“Why?” Porter asked.
“Because I left work.”
“Did you go to Sarah’s apartment?”
“Yes.”
“Was she alive when you left?”
“Yes.”
“What happened?”
“She confronted me. She said Emily had spoken to Anna.”
“Did you give Sarah drugs?”
“No.”
“Did you harm her?”
“No.”
“Who arrived after you?”
Thomas looked at his attorney.
Then he said, “My mother.”
Evelyn had claimed she visited before Thomas.
One of them was lying.

Thomas added one more sentence.
“She wasn’t alone.”
