Prosecutors: Hit Man Killed Federal Witness Linked to Staged 18-Wheeler Crash Scheme

Author: FreightWaves·

Key Takeaways

  • Disbarred attorney Sean Alfortish faces trial for allegedly conspiring to murder Cornelius Garrison, a federal witness slain in 2020 after cooperating with an FBI investigation.
  • The prosecution stems from a broader federal probe that has charged 63 defendants involved in a decade-long staged-collision scheme targeting commercial trucks.
  • Perpetrators targeted 18-wheelers to exploit federal regulations requiring high minimum liability coverage, making them highly profitable targets for fraudulent insurance claims.
  • The trial has drawn renewed attention to the proposed Staged Accident Fraud Prevention Act, which would establish specific federal penalties for intentionally causing commercial vehicle accidents.
Prosecutors: Hit Man Killed Federal Witness Linked to Staged 18-Wheeler Crash Scheme

A federal court in New Orleans began jury selection Monday for Sean Alfortish, a disbarred attorney accused of conspiring to murder a cooperating federal witness in connection with a sprawling staged-collision operation targeting commercial trucks.

Alfortish pleaded not guilty. The indictment identifies the slain witness, Cornelius Garrison, as a "slammer" — a driver who intentionally sideswiped 18-wheelers. Garrison later cooperated with the FBI during its investigation. He was fatally shot at his mother's home on Sept. 22, 2020.

Authorities charged Alfortish and Leon Parker with causing Garrison's death through a firearm.

Charges Linked to Staged-Crash Enterprise

Alfortish faces one fraud-conspiracy count, three obstruction charges, four witness-tampering accusations, and a conspiracy-to-commit-murder charge. An additional count accuses both Alfortish and Parker of causing Garrison's death through a firearm — an offense carrying potential life imprisonment and a $250,000 fine.

Prosecutors allege Alfortish attempted to relocate Garrison to the Bahamas before the shooting.

Ryan Harris pleaded guilty in January 2025 to causing death through a firearm. His plea agreement also covered wire fraud and a mail-and-wire fraud conspiracy. Authorities previously identified Harris as a participant in the collision-staging scheme.

Federal authorities have charged 63 defendants in the broader New Orleans probe. On March 20, a jury convicted attorneys Vanessa Motta and Jason Giles following a three-week trial. Their law firms were also found guilty. Those cases involved staged wrecks, fraudulent lawsuits, and insurance payouts.

Operation Spanned More Than a Decade

Court documents describe an operation that ran from December 2011 through December 2024. Participants recruited passengers and paid drivers to target 18-wheelers carrying large commercial insurance policies. Interstate freight carriers are required by federal regulation to maintain a minimum of $750,000 in liability coverage — and many carry substantially more — making them far more lucrative targets for fraudulent claims than passenger vehicles. Attorneys then filed claims seeking payouts for purposeful collisions. According to the Justice Department, some clients underwent medically unnecessary surgeries to inflate settlement values.

Staged collision fraud is a well-documented category of insurance fraud tracked by the National Insurance Crime Bureau and the FBI, with similar rings prosecuted in multiple states over the years. The FBI estimates that non-health insurance fraud costs more than $40 billion annually, contributing to higher premiums for commercial fleets and shipping costs ultimately borne by consumers.

WDSU reported that Chief U.S. District Judge Wendy Vitter limited evidence before the proceeding. The court barred prosecutors from introducing Alfortish's 2011 conviction, though her ruling permits references to his disbarment. Vitter also excluded Parker's 2010 arrest but allowed other information involving Harris.

Stephen Waguespack, president of the U.S. Chamber of Commerce Institute for Legal Reform, told FreightWaves: "What happened in New Orleans should be a wake-up call. The trial is a reminder of just how far these criminal enterprises can go: endangering lives, driving up costs for everyday Americans, and hijacking the legal system. Staged collisions targeting trucks put everyone on the road at risk, and the legislation we've been supporting would give federal authorities more tools to crack down on these rings before they evolve the way this one did in Louisiana."

Federal Legislation Gains Renewed Attention

U.S. Sen. Ashley Moody, R-Fla., introduced the Staged Accident Fraud Prevention Act in July. The proposal would create specific federal penalties for intentionally causing commercial vehicle collisions — a category not currently addressed by a dedicated federal statute. Participants could face up to 20 years in prison, with a minimum two-decade sentence for cases involving serious bodily injury or death.

The New Orleans prosecution does not stem from Moody's legislation. Investigators began their work years before the bill was introduced, and current charges rely on existing fraud, obstruction, witness-tampering, and firearm statutes. Reps. Mike Collins, R-Ga., and Brandon Gill, R-Texas, introduced companion legislation in the House in April 2025.

The case was investigated by the FBI, the New Orleans Police Department, and the Louisiana State Police, with assistance from several parish sheriff's offices and the Metropolitan Crime Commission. Federal prosecutors from Louisiana and the Justice Department are handling the trial. Prosecutors must prove every charge beyond a reasonable doubt.
