Authorities say two people died and a third was injured when an 18-wheeler in which they were riding ran off Interstate 12 near Lacombe, struck a tree and caught fire.

State police tell The Times-Picayune the injured person was taken to the Interim LSU Public Hospital in New Orleans with serious injuries.

Identities of the victims were not immediately released.

The tractor-trailer rig ran off the highway's eastbound lanes near the Lacombe exit in St. Tammany Parish.

Authorities say it could take up to three weeks to finish storing military propellant at an explosives recycling company that caused the evacuation of a Louisiana town.

The town of Doyline was evacuated earlier this month after authorities said they found 6 million pounds of the material improperly stored at Explo Systems Inc.

Explo contracts with the military to demilitarize explosives and other materials. The company rents space at a National Guard base in north Louisiana.

Louisiana's motor vehicles commissioner, Nick Gautreaux, is leaving the job in August.

Gautreaux told The Advocate that he is planning a career in corporate development and governmental work, a move that will keep him closer to home and his five children in Youngsville.

A former state senator, Gautreaux took the position as commissioner of the Office of Motor Vehicles in December 2010. His last day will be Aug. 5, according to a spokesman for the Louisiana State Police, which oversees the office.

The Louisiana State Police and the Department of Wildlife and Fisheries are exploring the possibility of a joint training academy as a way to recruit new officers and reduce agency costs.

State Police Superintendent Mike Edmonson said Wednesday that no date has been set for a possible class, according to The Times-Picayune.

Both agencies haven't held training academies because of the state's budget troubles.
