Two people died in separate accidents in St. Tammany Parish Friday and Saturday.

On Friday, Mandeville’s Don Audibert, 58, died when a truck smacked his Harley Davidson on Louisiana Highway 1083 and sent him airborne. On Saturday, a 22-year-old Huntsville, Ala. man, Jose Compean, died on Interstate 10 near Slidell when he was tossed from a flipping van.

The weekend’s death toll is St. Tammany’s 24th and 25th fatalities this year, said Trooper Louis Calato, spokesman for Louisiana State Police Troop L. In the first accident about 3:40 p.m. Friday, Audibert died on La. 1083 when a pickup truck hit his 2007 Harley Davidson motorcycle head on and sent him airborne.

Audibert was traveling in the southbound lane in front of another Harley Davidson driver, 36-year-old Heath Munch, of Madisonville, when an approaching Ford Ranger truck veered into their lane, Calato said.

The driver of the truck, Charles Westmoreland, 48, of Bogalusa, was thought to be drunk when he crossed the center lane, Calato said.

To avoid a collision, Audibert slammed on his brakes and fell into a skid before overturning on his side and smacking the front right side of the truck. Munch also slammed on his brakes but smacked Audibert’s motorcycle.

Audibert’s injuries were so severe he was pronounced dead at the scene, Calato said.

Acadian Ambulance transported Munch to St. Tammany Parish Hospital for treatment of moderate injuries. He was wearing a helmet not approved by the state Department of Transportation, Calato said.

Westmoreland was transported by Acadian Ambulance to St. Tammany Parish Hospital for moderate injuries. Upon his release, he’ll be arrested and charged with vehicular homicide, vehicular negligent injuring, driving left of center, expired inspection sticker, expired driver’s license, no seat belt, second offense operating a vehicle while intoxicated and illegal possession of the prescription painkiller Hydrocodone.

On Saturday morning, the weekend’s second fatality unfolded on Interstate 10 near Oak Harbor in Slidell when a red 1994 Nissan van was rear ended, Calato said. But instead of wrecking, the van caused the pickup truck that hit it to flip, tossing its passenger, Jose Compean, 22.

About 5:38 a.m., Francisco Aguilar, 19, an illegal immigrant with no driver’s license, was driving east on I-10 in a 1995 Nissan pickup when he rammed the back of the van in the right rear, Calato said. The impact sent the van into a tailspin, but it quickly regained control, veered off the right shoulder and stopped.

Meanwhile, the truck lost control and flipped several times, eventually tossing out and killing Com-pean. Another passenger, Candelario Olvera, 36, was transported to Northshore Regional Medical Center and treated for moderate injuries.

Aguilar, who was treated for moderate injuries, is suspected of drinking and driving. Alcohol tests are pending, but once he’s released from Northshore Regional Medical Center he’ll be booked with vehicular homicide, careless operation, no driver’s license, operating a vehicle while intoxicated, illegal alien operating a motor vehicle, first-degree negligent injuring, Calato said.

Authorities are also now looking for the driver of the 1994 Nissan van, which fled the scene of the crash. Anyone with information is urged to call Louisiana State Police at 893-6250.
