Criminal Charges: On April 18, 2022, Jason Nielsen was charged with one count of securities fraud for his involvement in a scheme to induce investors to purchase securities using deceptive and manipulative means. Nielsen was a large investor in Arrayit, a publicly traded medical technology company based in Sunnyvale, California, who frequently posted on public message boards about Arrayit under the name “PennyStockAlert”. According to the criminal information, beginning in or around 2019 and continuing through in or around 2020, Nielsen communicated and posted materially false and misleading information about Arrayit, the existence of genuine supply and demand for Arrayit securities, and the nature of his personal financial stake in Arrayit securities, all in order to fraudulently induce other investors to purchase Arrayit securities and thereby drive up the stock’s price, all while Nielsen simultaneously and secretly was selling his own previously acquired shares at an artificially inflated price. The purpose of the scheme was for Nielsen to enrich himself at the expense of other investors.

Presumption of Innocence: It is important to keep in mind that a criminal complaint is merely an allegation, and defendants are presumed innocent until proven guilty and that presumption requires both the court and our office to take certain steps to ensure that justice is served.

Crime Victims’ Rights Act and Right to Retain Counsel: The Crime Victims’ Rights Act (18 U.S.C. § 3771) applies only to victims of the counts charged in federal court, and thus individuals may not be able to exercise all of these rights if the crime of which the individual is a victim was not charged. Section 3771(c)(2) of this Act requires that we advise you that you have the right to retain counsel. Although the statute specifically sets forth your right to seek advice of an attorney with regard to your rights under the statute, there is no requirement that you retain counsel. The Government may not recommend any specific counsel, nor can the Government (or the Court) pay for counsel to represent you. Government attorneys represent the United States.

If you elect to obtain counsel to represent your interests, please have your attorney notify this office in writing at: U.S. Department of Justice, Criminal Division, Fraud Section, 10th & Constitution Avenue, NW, Bond Building, 4th Floor, Washington, DC 20530, Attention: Victim Witness Unit; fax: (202) 514-3708; or email: If you elect not to retain counsel to represent your interests, you do not need to do anything.

Plea Agreements: Please be aware that many criminal cases are resolved by plea agreement between the Department of Justice and the defendant. You should also know that it is not unusual for a defendant to seek to negotiate a plea agreement shortly before trial is scheduled to begin. Plea agreements can be made at any time and as late as the morning of trial, leaving little or no opportunity to provide notice to you of the date and time of the plea hearing. If the court schedules a plea hearing in this case, we will use our best efforts to notify you of available information as soon as practicable. If you want to inform the prosecutor of your views regarding potential plea agreements, or any other aspect of the case, please contact the prosecutor assigned to this case or call the Victim Assistance Line toll-free at (888) 549-3945 or email us at
