"The crash happened around 8:30 p.m. on Pennsville Auburn Road near Stumpy Lane in Oldmans Township.
Johnny, 31, and Matthew, 29, were traveling north on County Route 551, close to the line on the side of the roadway.
Police say 43-year-old Sean M. Higgins, of Woodstown, New Jersey, was traveling north on County Route 551 in a Jeep Grand Cherokee when he allegedly attempted to pass a slower-moving sedan and SUV.
Police say Higgins entered the southbound lanes of the roadway and passed the sedan.
When he attempted to reenter the northbound lanes, police say the SUV in front of him moved into the middle of the roadway, splitting the north and south lanes in order to safely pass two bicyclists on the right side of the road.
Higgins then attempted to pass the SUV on the right and struck the Gaudreau brothers from behind, troopers said.
The Gaudreau brothers died from their injuries, according to state police.
According to the police affidavit, the trooper who arrived on the scene detected a "strong odor of alcohol," and Higgins allegedly told the trooper he had consumed "five to six beers" before the crash.
Higgins allegedly told investigators that he thought the driver of the SUV was trying to stop him from passing. Higgins told investigators that his consumption of alcohol contributed to his impatience and reckless driving, according to the criminal complaint.
The trooper also said Higgins then failed a field sobriety test."
