Russell Laffitte, the former CEO of Palmetto State Bank who was convicted of conspiring with attorney Alex Murdaugh in a decade-long corruption schemes totaling millions of dollars, will appear in federal court Tuesday for a sentencing hearing.

Following a nearly three-week-long jury trial in November 2022, Laffitte was convicted of conspiring to commit wire fraud and bank fraud, wire fraud, bank fraud and three counts of misapplication of bank funds.

U.S. District Judge Richard M. Gergel, who presided over the trial, will impose the sentence. The sentencing comes as Gergel denied a new trial request, which was prompted after Murdaugh testified at his double murder trial in Colleton County, South Carolina that Laffitte was innocent of fraud.

"Russell Laffitte never conspired with me to do anything," Murdaugh testified prior to being convicted for the June 2021 murders of his wife, Maggie, and youngest son, Paul. At the time, Gergel said Murdaugh was not a "credible witness."

"Evidence offered during the Defendant’s trial established without question that Murdaugh is a serial liar and fraudster who stole from his clients and law partners," the judge wrote in April, denying Laffitte's request for a new trial. "He now stands convicted of the double homicide of his wife and son. It is difficult to imagine a less credible witness under these circumstances."

South Carolina prosecutors have said Murdaugh killed his wife and son to divert attention from his 99 financial crimes charges stemming from 19 separate indictments and totaling nearly $9 million. He was accused of embezzling money from his family's generations-old personal injury law firm and its clients.

A court determined in November 2022 that Laffitte helped Murdaugh steal those funds, though Laffittte maintains his innocence.

While an initial indictment charging Laffitte did not mention Murdaugh by name, it said the former bank CEO collected nearly $392,000 in fees for serving as a personal representative for the six clients of a "personal injury attorney at a law firm in Hampton, South Carolina," according to a July press release from the U.S. Attorney's Office, District of South Carolina.

Laffitte transferred personal loans to himself and Murdaugh from the six conservator accounts, and they used the funds for personal expenses, prosecutors said during his trial last year.

The Laffitte and Murdaugh families rose to South Carolina prominence around the same time in the early 20th century, when the Laffittes founded Palmetto State Bank, and the Murdaugh family began Peters Murdaugh Parker Eltzroth & Detrick – now known as The Parker Law Group.
