Key facts: Mark Ybarra was given a city credit card from 2018 to 2023 to hire repair companies for city buildings. He used it to pay 30 different vendors, but the city auditor could only verify that eight of them were real companies, according to the report. 

Ten of the companies reportedly had the same address, which the city auditor said is the home of one of Ybarra's relatives. The businesses received $400,000 from the city. One of them had Ybarra's email address listed as its contact information, according to the report.

The remaining $580,000 went to businesses that "appeared to be fake," many of which were missing basic information like an address and phone number, according to the report. 

Ybarra resigned in October 2023 after Austin Energy officials asked questions about the invoices, according to the report. He was indicted for felony theft this September. 

Records obtained by Open the Books show Ybarra earned $534,797 in taxpayer-funded salary during the six years he was allegedly defrauding the city.

The city auditor claimed the alleged fraud went undetected because of Austin Energy's "inefficient purchasing controls." Most of his purchases were approved by former Facility Service Supervisor Sammy Ramirez, who never raised questions about the missing addresses and phone numbers on Ybarra's invoices, according to the report.

Mark Ybarra's wife, Ambrosia Ybarra, worked at the city's Watershed Protection Department. She was questioned by the city auditor about her husband's invoices but allegedly left the interview before it was over, according to the report. She resigned this November.

Ambrosia Ybarra made $70,174 in 2024. Ramirez made $87,262 in 2022, his last year of employment, but made as much as $104,698 in 2021.

Summary: Austin's scandal is yet another reminder that the government agencies spending huge amounts of money relative to the population of the areas they serve are often the ones most vulnerable to mistakes and fraud.
