Louisiana Man Drowns Inside Car After Getting Stuck Under Overpass During Flash Flooding On 5/19/21 at 4:53 AM EDT A Louisiana man was found dead inside his vehicle after his car was one of many to become submerged during flash flooding in the state. The man, 33-year-old Justin Blaine Thompson, from Gonzales, Louisiana, was discovered dead trapped inside his car at around 10:20 a.m. on Tuesday under the railroad overpass at Bluebonnet Boulevard near the Mall of Louisiana, according to a statement by the East Baton Rouge Sheriff's Office. Several cars became trapped underneath the overpass on Monday evening through to Tuesday morning, as heavy rain caused cars to become submerged as vehicles blocked others from moving.
