Derek Simmons’s hospital attack transformed a psychiatric commitment into a lasting rupture in his identity: although his brain could form new memories, the past he had lived before the assault became inaccessible to him. The injury also shaped how others later judged his testimony about the crimes surrounding Joseph Wieder.

Diagnosis and the Hospital Attack

After examining Simmons several times, Wieder concluded that he had a rare dissociative disorder and had been wrongly diagnosed with schizophrenia when young. Wieder’s account described episodes of fugue in which a person could lose self-awareness, memory, and any sense of identity, sometimes disappearing and living under a different identity. He considered it possible that Simmons might not remember what he had done on the night in question, having reacted under stress and in a state of altered consciousness while abruptly waking from sleep.

Wieder’s report persuaded the court to commit Simmons to Trenton Psychiatric Hospital. With the institution and Simmons’s lawyer in agreement, Wieder continued treating him there with hypnosis and an experimental combination of anticonvulsant drugs. After several months, another patient attacked Simmons, leaving him with a serious head wound that substantially worsened his condition.

The consequences were profound and permanent: Simmons lost his memory, and the memories from before the attack never returned. He could still form and store new memories, but the injury had made his earlier life inaccessible—a condition Laura identified as retrograde amnesia. The distinction became central to the account of his later life: Simmons retained abilities acquired before the assault, yet could no longer remember the personal history through which he had acquired them.

Reconstruction and Supported Independence

A year after the attack, at Joseph Wieder’s insistence, Derek Simmons was transferred to Marlboro Psychiatric Hospital, where the less restrictive regime gave Wieder room to help him rebuild a life. That reconstruction restored a name and outward identity, not his autobiographical memory. Simmons could write without remembering school, and work as an electrician without remembering how he had learned the trade; the memories of his earlier life remained inaccessible even as the skills endured.

In spring 1985, a judge approved Simmons’s discharge because of the case’s complexity and his complete lack of violent tendencies. But release did not mean he could manage alone. He had no employment prospects, his mother had died when he was a toddler, and his estranged father had left without a forwarding address. Wieder rented him a small one-bedroom apartment near his own home and paid him to maintain the house. Simmons lived by himself, and neighbours regarded him as a freak; when he shut himself away for days or weeks, Wieder brought him food and checked that he took his medication.

The arrangement made Wieder more than Simmons’s former doctor: it supplied housing, paid work, treatment, and the practical care that made life outside an institution possible. Simmons revered him and seemed gentle and incapable of harming anyone. He also adopted a shelter puppy, Jack, and took him for an evening walk in the nearby park. These modest routines show the fragile, supported independence that followed the loss of his past.

The Return of Memory and the Cost of Testimony

The assault’s effects did not remain a simple, permanent blank. In mid-March 1987, while watching NY1, Simmons recognized a man reported to have died by suicide as Stan Marini, a former member of the maintenance crew at Siemens, where Simmons himself had once worked. The connection mattered because no one had told him about it and he had not read it; he took the recognition as evidence that something from his buried past was surfacing independently. He described the change as a lid lifting and memories rushing up at extraordinary speed. This moment complicates the earlier account that his pre-injury memories could not be recovered: it records a sudden return of material, not proof that his autobiographical past had been restored in full.

That uncertainty shaped the value others assigned to Simmons’s claims about Joseph Wieder’s murder. He later told Roy Freeman that he knew who had killed Wieder and had said so at the time, but believed his statement had been dismissed because he had previously been accused of murder, confined in a psychiatric hospital, and treated as mentally ill. His account was specific: he believed Richard Flynn had stayed nearby after leaving Wieder’s house, returned, and killed the professor, while Laura Baines was either an accomplice or a witness. Simmons said he had withheld Laura’s name from the police because he feared publicity would tarnish Wieder’s reputation.

The account was not stable across tellings. When Freeman compared it with Frank Spoel’s version, Simmons had placed himself hiding in the backyard at the same time Spoel said he was there, yet the two accounts differed over Laura’s presence and whether Flynn and Wieder had argued. Simmons suggested Spoel might have forgotten or lied, but the contradiction left his own testimony under suspicion. Earlier, police had also treated his amnesia and illness as reasons his statement could not be used, while noting that there was no proof of an affair between Laura and Wieder and that she had an alibi. The attack thus continued to govern the investigation long after the wound healed: Simmons’s lost past, emerging recollections, and psychiatric history made him both a possible witness to the murder and a witness whose credibility could not be settled by conviction alone.

The Attack Within a Larger Problem of Memory

The hospital attack gives the novel’s inquiry into memory a concrete, bodily rupture, but it sits beside a different danger: recollection can feel vivid and still have the wrong source. Laura explains that Richard had long believed he watched the 1970 Super Bowl, only to recognize that he was four at the time and knew the game through his father’s repeated stories. A remembered scene can therefore be assembled from what was heard and later mistaken for what was lived; Simmons’s lost past raises the inverse problem, in which abilities survive after the personal experiences behind them have vanished.

Wieder’s mall experiment sharpens that contrast. Under hypnosis, three-quarters of students who could not recall getting lost in a mall came to describe such an event, including their fear, their recovery by clerks, and announcements over the speakers. Their detailed certainty did not establish that the event had happened. Against these examples, Simmons’s injury cannot simply be treated as a universal explanation for unreliable testimony: it accounts for a profound break in his access to the past, while the novel’s other cases show how memory can also be reshaped by suggestion, stories, and inference. The attack thus leaves the investigation with no easy equation between confidence and truth, or between memory’s absence and the absence of evidence.
