One Mammoth man dead, another seriously injured in Wyoming crash

One Mammoth man was killed and another seriously injured after a horrific rear-end collision on Interstate 80 Saturday afternoon in Wyoming.

The Wyoming Highway patrol said William "Bill" Krawisz, 26, was killed in the accident, while Travis Mann was seriously injured.

Mann's dog, Nova, also died in the crash, which occurred on Interstate 80, 10 miles outside of Laramie.

At least two passengers also were injured in the crash.

Mann is a full-time employee at Mammoth Brewing Co.. Krawisz volunteered there from time to time and Nova, a seven-year-old Siberian Husky, was a fixture at the tasting room.

Mammoth Brewing posted the news on its website, and announced a memorial service will be upcoming, details to come.

"We're all just horrified," said Mammoth Brewing employee Nora Urdi.

Sean Turner, owner of the Brewery, said the group was on its way back from a Phish concert.

"There's just this sadness at Mammoth Brewery," he said. "We love Travis and Nova was a real part of the tasting room. This is a bummer all the way around."

Mann was in an intensive care unit at a nearby hospital, but was taking calls from family and close friends.

According to the WHP, the two men were headed uphill, east on I-80 in their Volkswagen van, but could only muster 40-50 miles in an hour in the vehicle.

Behind them, a semi-trailer truck came barreling up.

"Both vehicles were on a straight section of roadway going up a slight uphill grade, the driver of the truck told investigating troopers that he looked to his left and reached for his cell phone to answer it.

"When he looked back down the roadway he realized that the van was directly in front of him."

The Highway Patrol said evidence at the scene indicates that the driver stomped on his brakes and steered his combination to the left in attempt to avoid a collision into the rear of the van vehicle, but it was too late.

The Highway Patrol said the right front of the truck tractor struck the left rear of the VW van.

Upon impact, the Mann vehicle went off the roadway on the right side where it spun and then rolled two complete times.

"All the occupants in the Mann vehicle were totally ejected from the van during the rollover," the Highway Patrol said.

The driver's tractor-trailer combination came to rest across both westbound lanes.

All westbound traffic was delayed as traffic through the crash scene was reduced to one lane of travel until the scene could be investigated and then the roadway cleared.

The driver was cited for careless driving.
