Jason Siebert-Thomas Sentenced to 4.5 years in Prison for Using Credit Cards of Deceased Individuals

PHOENIX – Attorney General Mark Brnovich announced Jason Siebert-Thomas, who admitted to using credit cards of deceased individuals, will spend more than four years in prison.

On October 3, 2018, the Honorable Judge Douglas Gerlach sentenced Jason Siebert-Thomas to 4.5 years in the Arizona Department of Corrections, followed by three years of supervised probation. 

Starting in August of 2016, Tempe Police Department and Glendale Police Department learned Siebert-Thomas was being added as an authorized user to credit card accounts belonging to deceased individuals.  Family members of the deceased individuals indicated Siebert-Thomas had no relationship to the deceased individuals, and that the credit card company was contacted after the individual had passed away.  Frequently, the address on the credit card account was changed to the address where Siebert-Thomas was residing. 

Through surveillance video and photos, detectives identified Siebert-Thomas using multiple credit cards in which he had been added as an authorized user.  A number of the purchases exceeded $5,000. At his home, detectives say they located several notebooks containing handwritten notes with the personal identifying information for various deceased individuals. During an interview, Siebert-Thomas admitted to purchasing items with the credit cards. The investigation identified eight separate times that Siebert-Thomas was added to a credit card account after the named account holder had passed away. Additionally, Siebert-Thomas gave one of the credit cards to Daylon Pierce, who plead guilty to deceiving women in an elaborate online dating scam, which was investigated by the FBI Phoenix Field Office. Siebert-Thomas was indicted on January 23, 2017, in CR2017-102122-002 for these offenses.

While Siebert-Thomas was on release for his pending charges, Tempe Police Department received a report that Siebert-Thomas was falsifying work tickets submitted to his employer. According to investigators, Siebert-Thomas submitted a number of work tickets for days he never reported for work. Additionally, he used his supervisor’s signature without his authorization. Siebert-Thomas was indicted on March 26, 2018, in CR2018-113270-001 for these offenses. These matters were jointly investigated by the Tempe Police Department, the Glendale Police Department, the Paradise Valley Police Department, and the Phoenix Field Office of the FBI. 

In CR2017-102122-002, Siebert-Thomas plead guilty to: one Count of Fraudulent Schemes and Artifices, a class 2 felony; one count of Aggravated Taking the Identity of Another Person or Entity, a class 3 felony, and Taking the Identity of Another Person or Entity, a class 4 felony. 

In CR2018-113270-001, Siebert-Thomas plead guilty to: one Count of Taking the Identity of Another Person or Entity, a class 4 felony, and Theft, a class 4 felony.

This case was prosecuted by Assistant Attorney General Scott Blake.
