The St. Tammany Parish Coroner’s Office on Wednesday confirmed the identities of two motorists killed in a Tuesday afternoon accident at U.S. 190 and Fairway Drive near Mandeville as 63-year-old Corinne Talbert, of Madisonville, and 54-year-old Gordon Johnson, of Covington.

Coroner Charles Preston said both died as a result of their injuries, but that Johnson also had significant heart disease, which may have been a contributing factor in the accident. Toxicology reports are pending, Preston said.

According to Louisiana State Police Troop L, Johnson was driving a 2013 Ford Edge southbound on U.S. 190 when he veered to the right and sideswiped a 2007 Jeep. He then exited the roadway to the left, entered the median and traveled southbound until he entered the northbound lanes, heading south in the center lane. He traveled about half a mile before striking a Toyota Avalon driven by Talbert.

His vehicle became partially airborne as it rotated and was struck by a Toyota Tundra in the left lane. Johnson’s car also struck the right front corner and top right side of a Chevrolet Tahoe while airborne before finally coming to rest against the Toyota Tundra that was partially in the median.

Johnson and Talbert were pronounced dead on the scene. One other driver suffered minor injuries.

The four-vehicle accident blocked U.S. 190 northbound during the afternoon rush.

The St. Tammany Parish Sheriff’s Office, Mandeville Police Department, Louisiana Probation and Parole, and St. Tammany Fire District 4 from Mandeville assisted Troop L with directing traffic during the investigation.
