Fatal Memorial Day Motorcycle Crash on Interstate 20 in Monroe Louisiana

MONROE, LA – On Tuesday May 30, 2023, the Louisiana State Police reported that on Monday, May 29, 2023, shortly after 9:00 P.M., Troopers from Louisiana State Police Troop F began investigating a two-vehicle fatal crash on I-20 westbound just west of the Millhaven Exit.

This crash claimed the life of 36-year-old Alisha Adcock of Metairie.

The preliminary investigation revealed that a 2006 GMC Yukon, driven by 52-year-old Leon Patrick Jr., was traveling west on I-20 in the outside lane. At the same time, a 2001 Suzuki motorcycle, driven by Adcock, was also traveling west in the outside lane of I-20. For reasons still under investigation, the GMC struck the rear end of the Suzuki.

As a result of being struck, Adcock, who was not wearing a DOT approved helmet, was ejected from the Suzuki and became trapped under the GMC. As a result of this crash, Adcock suffered fatal injuries. She was pronounced deceased at the scene by the Ouachita Parish Coroner’s Office.

Patrick Jr., who was unrestrained and not injured, was taken into custody at the crash scene after displaying signs of impairment. He was transported to the Ouachita Correctional Center, where he voluntarily submitted a breath sample, which indicated a Blood Alcohol Concentration (BAC) over the legal limit. He was booked into OCC for Vehicular Homicide and Careless Operation.

A routine toxicology sample was collected from Adcock and will be submitted for analysis. This crash remains under investigation.

Time and time again, Troopers witness preventable motor vehicle crashes. Impairment and lack of seat belt usage are the primary causes of crashes across the state. Louisiana State Police urge motorists to have a plan in place that includes a designated driver when consuming alcohol. Alcohol can impair visual ability, alter the sense of time and space, impair fine motor skills, and decrease reaction times. Alcohol can begin to impair a person's ability to safely operate a motor vehicle after just one drink. Please choose not to drive impaired or ride with an impaired driver, and always buckle up.

Troopers also encourage all riders to take an approved motorcycle safety course. These courses teach safe riding practices and help you apply safe riding strategies that can help reduce your chance of injury should a crash occur.
