A California rapper known as ColdheartedAC and two co-defendants face federal charges for stealing more than $8.1 million through an elaborate check fraud scheme. Hoodline reports that Ada William Obayuwana, 31, Albert Tai Vu, 28, and Cassandra Marie Murrillo, 31, allegedly forged endorsements, altered names and addresses, and cashed stolen government checks across Southern California between April 2022 and December 2023.
Authorities discovered over 100 stolen checks in Obayuwana's Oceanside vehicle during a December 2023 search, totaling more than $6.1 million. KESQ notes that 48 of those Treasury checks were worth about $2.55 million, with eight already cashed for roughly $1.7 million. Each defendant now faces decades in federal prison if convicted.
The trio targeted government benefit checks, including tax refunds, veterans' benefits, and Social Security payments. Patch reports they opened fraudulent bank accounts to receive the stolen funds and systematically cashed checks through a coordinated operation spanning Los Angeles, Orange, and San Diego counties. The scheme ran for over a year and a half before authorities caught on.
When police searched Obayuwana's vehicle in Oceanside in December 2023, they uncovered a stash worth $6.1 million in stolen or fraudulent checks. Among these were 48 U.S. Treasury checks valued at about $2.55 million. Eight of those Treasury checks had already been successfully cashed, netting the criminals roughly $1.7 million before their arrest.
Obayuwana faces nine counts of bank fraud plus three counts of delivering stolen Treasury checks and one count of aggravated identity theft. Patch reports that Vu faces five counts of delivering stolen Treasury checks, four counts of money laundering, and two counts of aggravated identity theft. Murrillo is charged with delivering stolen Treasury checks and other offenses. Obayuwana remains in federal custody while the other two await initial appearances.
