Los Angeles aspiring rapper Ada William Obayuwana, known professionally as “ColdheartedAC,” was arrested and federally charged alongside two accomplices for allegedly orchestrating an $8.1 million stolen check-cashing scheme spanning Southern California, federal prosecutors announced.
Obayuwana, 31, stands accused of nine counts of bank fraud, three counts of delivering stolen Treasury checks, and one count of aggravated identity theft, according to the U.S. Attorney’s Office for the Central District. Federal investigators arrested the aspiring artist on Wednesday, bringing a swift halt to a fraud operation that targeted federal relief funds and taxpayer benefits.
The Anatomy of an $8.1 Million Federal Check Fraud Operation
Between April 2022 and December 2023, federal authorities state that Obayuwana and his co-conspirators managed to acquire and process over 50 stolen U.S. Treasury checks. These documents were not standard commercial drafts; they represented vital government disbursements including tax refunds, veterans’ benefits, and Social Security Administration (SSA) payments.
The operation relied on systematic forgery and institutional exploitation. Prosecutors detail that the defendants forged endorsements on the stolen checks before establishing new bank accounts specifically designed to funnel the illicit funds. Albert Tai Vu, 28, of Westminster, and Cassandra Marie Murrillo, 31, of San Diego, joined Obayuwana in the indictment, facing a web of bank fraud, money laundering, and identity theft charges.
Financial tracing by investigators revealed the staggering scale of the payouts. During the active window of the conspiracy, Vu successfully cashed two tax refund checks totaling more than $772,000. Meanwhile, Obayuwana himself reaped nearly $1.7 million across eight separate checks deposited in December 2023 alone.
Social Media Flash and the Contrast of Federal Custody
While the federal check fraud scheme operated in the shadows of the banking sector, Obayuwana cultivated a very public persona under his moniker “ColdheartedAC” and “AC.” Boasting nearly 400,000 followers on Instagram, the 31-year-old regularly posted images showcasing a high-rolling lifestyle, including photographs alongside boxing icon Floyd Mayweather.
His digital footprint also extended to video platforms, where he maintained over 3,000 YouTube subscribers and accumulated over 194,000 views on a single musical release. That public display of affluence stands in stark contrast to his current legal reality. Following his arrest on Wednesday, Obayuwana attended his initial appearance at a Los Angeles federal court and underwent a detention hearing on Friday, where he was ordered to remain in federal custody.
Legal Repercussions and Co-Defendant Charges
The charges filed by the Department of Justice carry severe statutory penalties reflecting the multi-jurisdictional and federal nature of check and identity fraud. Obayuwana faces nine distinct counts of bank fraud alone, alongside aggravated identity theft enhancements.
Co-defendant Albert Tai Vu faces five counts of delivering stolen Treasury checks, four counts of money laundering, and two counts of aggravated identity theft. Cassandra Marie Murrillo is charged with delivering stolen Treasury checks alongside her co-conspirators.
As the case proceeds through the U.S. District Court for the Central District of California, federal investigators continue to examine the wider network responsible for intercepting the U.S. Treasury documents. What started as an aspiring rap career fueled by luxury social media posts has collided with the enforcement mechanisms of the federal justice system.
