Major ARPA Case Concludes with Sentencing of Second Suspect
Public Lands in Nevada and California • October 2011

Thousands of artifacts have been returned to the California Native American Heritage Commission and two men have been sentenced as a result of a multi-agency investigation into violations of the Archeological Resources Protection Act (ARPA) on public lands. ISB Special Agents, US Fish and Wildlife Service (FWS) officers, US Park Rangers, and rangers of Sacramento County Parks collaborated on the case, serving a search warrant at a Sacramento residence in March of 2007. The residents were believed to have taken artifacts from National Park Service, US Forest Service, FWS, and Sacramento County Park lands. Interviews resulted in admissions that the residents went to northwestern Nevada on two occasions (2003 and 2006) and collected artifacts from Bureau of Land Management (BLM) land. The residents knew this activity was illegal and these artifacts were recovered at their home. The suspects also admitted removing artifacts from other publicly owned lands. Investigators found and seized computers, GPS units, maps, photographs showing the residents searching for and collecting artifacts, and other documentary evidence. Officers also discovered approximately 38,000 artifacts on the property and in the vehicles associated with the property. These artifacts included beads and other burial objects, such as abalone breastplates and pendants, projectile points, mortars, pestles, metates, and stone tools. About 100 evidence lots were seized that included roughly 500 artifacts that may have come from federal lands. In June of 2008, damage assessment field work was conducted at the looted site in northwestern Nevada. This resulted in the documentation of over $15,000 in damage. Two of the residents, a father and adult son, were indicted in October of 2008 on four felony counts including ARPA violations, conspiracy, and theft. In July of 2010, after extensive negotiations, the father agreed to surrender approximately 30,000 non-federal artifacts to the California Native American Heritage Commission. These artifacts, predominantly burial goods, were then returned to the appropriate tribes by the commission.The father was sentenced in July to three years probation including six months home detention, a $3,600 fine, and $100 special penalty assessment based on his one count felony ARPA conviction. In October, following a three hour sentencing hearing that included testimony by a BLM archeologist and Native American tribal representatives, the adult son was sentenced to 30 days in prison, three months home detention and one year of supervised release for his one count misdemeanor ARPA conviction.

Former Federal Employee Indicted for Embezzling approximately $730,000
Colorado Public Lands • October 2011

Lydia White, age 48, was named in a 198-count indictment on October 5, 2011. White, a resident of Colorado, worked for the National Park Service (NPS) at the time of the offenses and was charged with 145 counts of theft of government property and 53 counts of money laundering in connection with embezzling approximately $730,000 in money taken from her employer. These charges are allegations, and the defendant is presumed innocent unless and until proven guilty in a court of law. Following an investigation by ISB Special Agents and the IRS Criminal Investigation unit, court documents allege that White willfully and knowingly stole money from the NPS for her own use and that of another from March of 2007 through December of 2010. Her actions deprived the NPS of the use and benefit of the involved funds. Court documents further allege that White conducted financial transactions affecting interstate commerce knowing the property involved represented the proceeds of her unlawful activity, and knowing that the transactions were designed to disguise the nature or source of the unlawfully-obtained proceeds. Assistant US Attorneys are conducting the prosecution.

  • "Thanks to the hard work of the National Park Service and the IRS Criminal Investigation, a corrupt government employee who was embezzling hundreds of thousands of dollars has been caught, and will be prosecuted to the fullest extent of the law," said US Attorney John Walsh.
  • "The apparent fraud and embezzlement by this former National Park Service employee is an affront to the taxpayer and the tens of thousands of public servants who do their job honorably and honestly every day," said National Park Service Director Jon Jarvis. "The response to these reprehensible activities should send a strong and clear signal that abuse of the public trust cannot and will not be tolerated."
  • "The role of IRS Criminal Investigation becomes even more important in embezzlement and fraud cases due to the complex financial transactions that can take time to unravel," said Sean Sowards, Special Agent in Charge of IRS Criminal Investigation. "This investigation serves to remind us that there is no such thing as free money and there are no awards or incentives for creativity when it comes to crime."

If convicted of theft of government property, White faces up to 10 years in federal prison and a fine of up to $250,000 for each count. If convicted of money laundering, she faces up to 20 years imprisonment per count, and a fine of up to twice the value of the property involved (or approximately $1,476,863). White also faces a possible order to pay restitution. The indictment includes an asset forfeiture allegation, which states that the defendant shall forfeit all of her interest in any property, real or personal, that consists of or is derived, directly or indirectly, from proceeds traceable to the commission of the offenses stated in the indictment.
