Fowler White Clients Allege First Horizon Failed to Stop $6.5 Million Fraud Despite Prior Warning Signs

Three Florida lawsuits allege more than $24 million in unauthorized transfers involving similar account takeover tactics

Fowler White Burnett attorneys representing K&A Rosario Holdings, LLC and MJR Fund I, Inc. have filed an amended federal complaint against First Horizon Bank seeking reimbursement of more than $4.5 million remaining from approximately $6.5 million in allegedly unauthorized wire transfers.

The complaint alleges First Horizon permitted the transfers despite prior knowledge of similar fraudulent activity involving other customers. Three pending Florida lawsuits collectively allege more than $24 million in unauthorized or fraudulent transfers between December 2025 and March 2026.

According to the amended complaint, an unauthorized caller contacted First Horizon on March 3, 2026, requesting assistance accessing an account after claiming to have a new cellphone. Within minutes, the accounts were allegedly accessed from an unfamiliar New York IP address. Approximately $6.52 million was subsequently transferred to recipients with whom K&A and MJR allegedly had no prior business relationship.

The complaint alleges First Horizon had been notified in January of an earlier account takeover involving Rabideau Klein, P.A., which alleges approximately $17.28 million in unauthorized wires. The K&A/MJR complaint further alleges $2.29 million went to the same overseas recipient associated with transfers during that earlier incident. A third lawsuit by Nosich & Ganz alleges approximately $604,500 in unauthorized transfers following a December 2025 account takeover.

"The allegations raise serious questions about what First Horizon knew following the earlier incidents and what measures were taken to protect customers from similar attacks," said Victor M. Velarde, a shareholder at Fowler White. "Our clients are seeking recovery of more than $4.5 million that remains unreimbursed."

Velarde and Chloe M. Horton of Fowler White represent K&A and MJR in the federal action pending in the U.S. District Court for the Middle District of Florida.
