Detectives then confronted James with physical evidence from the apartment. They asked how so much blood had ended up on the wall near the chair and television. James again tried to explain it as the result of Robert picking at himself. Investigators told him the pattern was not consistent with simple skin picking and instead appeared consistent with blood being projected during blunt-force trauma.
James continued resisting the conclusion. He insisted he would never hurt Robert that way and suggested investigators had already made up their minds. But police had also photographed bleach containers in the bathroom. When asked whether the bleach had been used to clean blood, James denied it and said the containers were old and that Robert was usually the one who cleaned the floors.
The detective told James he needed a believable explanation because, taken together, the blood, the injuries, the history, and the witness statements made it look as though Robert had been severely beaten inside the home. James said he was not going to jail for something he had not done. By that stage, however, investigators no longer needed him to confess. The cameras inside the house were about to answer questions that interviews had not.
The detectives then began the most damaging comparison in the case: James's interview against his own security system. In person, he had described himself as the man begging Robert to rest, eat, and accept help. He said he had offered an ambulance and reassured Robert that he would be taken care of. On camera, however, the language was often impatient and threatening, and it showed that James and Teresa had been discussing Robert's condition in real time while he was visibly deteriorating.
James had told officers on the night of the emergency that he treated Robert like a brother. He claimed he had offered to call an ambulance and reassured Robert that he would take care of him. The home-security footage showed a very different tone. Instead of the gentle caretaker James described, the recordings captured impatience, hostility, and conversations that directly undercut his account.
In one recording, James told Robert to get up and start moving, urging him not to give up. His tone did not match the compassionate story he later gave police. In another conversation, while speaking with Teresa, James made an extraordinary statement: "I don't control Robert, only when he pisses me off." He then said that at that moment he did not feel like beating Robert in the head and that he could beat him later.
The phrase about being able to beat Robert later was especially significant because James had repeatedly told detectives that he would never do that to him. The recording also undermined the idea that every serious injury had arrived with Robert from some unknown attack near the railroad tracks. Even when the exact origin of every mark could not be established from one camera angle, James's own words showed a level of hostility that had been absent from his carefully constructed description of brotherly care.
That recorded language was difficult to reconcile with James's repeated claim that he had never laid a hand on Robert. Teresa was also heard discussing Robert's refusal to seek medical care and portraying him as stubborn. The conversations suggested that both James and Teresa knew Robert was in serious condition while resisting outside intervention. Investigators began comparing every statement they had given with the timestamps and audio captured inside the house.
Teresa's side of the recorded calls also mattered. She could be heard reinforcing the idea that Robert was stubborn and did not want an ambulance, while James discussed his condition and what should be done. Later, both of them would describe the situation as though Robert alone had prevented medical intervention. Detectives now had recordings showing that the decision-making around his worsening condition was far more complicated than that simple explanation suggested.
James had claimed that when he realized Robert was not breathing, he immediately tried to save him. The footage showed James struggling to determine whether Robert was breathing and talking through what he should do. At one point he considered calling for help and describing Robert as someone who had simply been beaten up elsewhere. The recordings suggested hesitation and concern about what police or medical responders might discover.
The footage around the final emergency was fragmented but revealing. James checked Robert, questioned whether he could feel a pulse, and spoke aloud about what he might tell emergency personnel if he called. At moments, he sounded uncertain whether Robert was still breathing; at others, the conversation drifted toward how the injuries would be explained. That was very different from his later description of an immediate, uncomplicated rescue attempt.
In another portion of the footage, James could be seen walking through the kitchen carrying an object that appeared to investigators to be a hammer or mallet. The source footage did not establish through that image alone exactly what role, if any, the object played in Robert's injuries. But its presence added to the investigators' concern when considered beside the autopsy findings, the blood evidence, and James's own recorded statements.
After responders had come and gone, the recordings continued preserving conversations that James could not later erase. He and Teresa discussed what might happen if Robert died and how police would interpret the scene. James referenced blood in the kitchen and tried to frame it as something old, while also talking about the possibility of an investigation. The private tone of those discussions sharply contrasted with the innocence and confusion he presented during formal questioning.
