New Orleans – On August 23, 2024, just after 7:30 a.m., Troopers with Louisiana State Police Troop B responded to a multi-vehicle crash on the Crescent City Connection bridge. The crash claimed the life of 48-year-old Mark Deane of Gretna.

The preliminary investigation revealed that Deane was driving a 2021 Yamaha motorcycle eastbound on the Crescent City Connection bridge. At the same time, 29-year-old Alberto Martinez-Sanchez of Gretna was driving a 2000 Toyota Camry behind the Yamaha. For reasons still under investigation, the Toyota struck the rear of the Yamaha, causing Deane and the Yamaha to become airborne. The Toyota then collided with the rear of a 2023 Nissan Rogue. This crash remains under investigation.

Deane, who was wearing a DOT-approved helmet, was pronounced dead at the scene. Martinez-Sanchez was properly restrained and not injured in the crash. The driver of the Nissan was also properly restrained and uninjured. Impairment is not suspected, however standard toxicology samples were submitted for analysis.  

As a result of the investigation, Martinez-Sanchez was arrested and booked into the Orleans Parish Lockup for Negligent Homicide and other traffic-related charges. 

Troopers wish to remind motorists to always make safe and responsible decisions when driving. Never drive impaired, fatigued, or distracted. Always follow traffic laws and ensure that every occupant is properly restrained. While not all crashes are survivable, taking these simple precautions can often mean the difference between life and death.
