Southlake police detective solves $300k money laundering scheme
The Southlake Police Department praised a detective’s work in solving an alleged $300,000 money laundering plot that began in 2019.
Detective Jamie Hannah, a 10-year veteran of the department, worked the case after reports from a local business revealed a scheme that involved rerouting money from company funds to a personal Square account by using a name that was close to the business name, police said.
In October 2025, a woman named Lindsi Johnson was arrested in Grayson County on charges of money laundering in connection with the case that Hannah was working on in Southlake, according to a police spokesperson.
“Through multiple search warrants, detailed financial analysis, and coordination with six separate banking institutions, he traced the flow of funds across numerous accounts,” Southlake DPS said in the statement.
The department said Hannah worked with “diligence” and “persistence” with both the victim and financial institutions to solve the case.
“Financial crime investigations of this magnitude require patience, technical expertise, and an unwavering commitment to detail. Detective Hannah worked closely with the victim business and financial institutions to ensure every financial stream was identified, documented, and presented in a manner that would support successful prosecution,” the department posted on Facebook.
“Reflecting on the work behind cases like this, Detective Hannah shared a simple but meaningful perspective: ‘Behind every badge is a commitment to community.’”
