A Houma, LA, officer was killed in a single-vehicle crash Thursday morning near Thibodaux, authorities said. 

The crash killed 21-year-old Austin Bush of Houma, Louisiana State Police said. 

Authorities said the crash occurred shortly before 6 a.m. in Terrebonne Parish.  

Bush was traveling west in a fully marked police 2010 Ford Crown Victoria when he struck a log near the westbound fog line and veered across the eastbound lane and into a drainage basin, State Police Troop C said in a news release. He then became submerged in water, Houma Today reports. 

Bus was pulled from the submerged patrol unit and transported to Thibodaux Regional Medical Center, where he died shortly thereafter, authorities said. 

The crash remains under investigation.
