According to court documents, in March 2024, Sigl communicated with an individual he believed to be the father of a 10-year-old girl, but who was in fact an undercover officer. Sigl communicated his desire to perform sex acts on the child and planned to meet the undercover officer and child at a designated site to do so. When Sigl came to the designated site, he was arrested by law enforcement officers. Several sex items were recovered from his vehicle parked outside.

This case is the product of an investigation by the Sacramento County Sheriff’s Office and the Sacramento Valley High Tech Crimes Taskforce. Assistant U.S. Attorney Zulkar Khan is prosecuting the case.

Sigl is scheduled to be sentenced by U.S. District Judge John A. Mendez on Oct. 7, 2025. Sigl faces a maximum statutory penalty of life in prison and a $250,000 fine. The actual sentence, however, will be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables.

This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by the United States Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute those who sexually exploit children, and to identify and rescue victims.
