Neal Sidhwaney, 43, of Fernandina Beach, admitted to transmitting an interstate threat to kill in a voicemail directed at Roberts on July 31. The specific member of the high court targeted was not specified by the Justice Department, but a psychologist's report from September identified Roberts as the intended victim.

In the voicemail, Sidhwaney can be heard saying, "I will f-king kill you... Go f-king tell the Deputy US Marshals you f-ing p-y." He further stated, "I will f-king talk to them and then I'll f-ing come kill you anyways, you f-ing c-."

The September evaluation conducted by Dr. Alan J. Harris determined that Sidhwaney, who suffers from "delusional disorder with psychosis," was fit to stand trial. He has been receiving treatment with an antipsychotic drug. The psychologist's report revealed that Sidhwaney's paranoia began in 2017, after leaving his position as a programmer at Google, where he had worked for eight years. According to his parents, he believes that a private agency has been tracking his movements. Sidhwaney's mother also noted that he often becomes enraged while watching the news, prompting him to write letters, emails, or make threatening phone calls.

Security concerns surrounding the justices have been heightened, particularly in the aftermath of the decision last year to overturn Roe v. Wade. This incident follows another case in June 2022, where Nicholas Roske, a California man, was charged with plotting to kill Justice Brett Kavanaugh and later arrested outside Kavanaugh's Maryland residence. In response to the increased threats, President Biden signed legislation in the same month, extending security protection to the families of the justices.

Sidhwaney's guilty plea highlights the ongoing challenges related to mental health and security in the United States. The case against him serves as a reminder of the importance of ensuring the safety and well-being of public figures and the need for continued efforts to address mental health issues in society.
