BLAINE, Wash. -- An 18-year-old man was killed while driving a steamroller at a construction site near Blaine early Tuesday, said police.

Police responded to a construction site in the 8500 block of Semiahmoo Parkway around 12:30 a.m. to find 18-year-old Justin Wydur trapped under the steamroller, said the Whatcom County Sheriff’s Office.

Wydur was driving up a dirt pile when the steamroller overturned and killed him immediately, said the sheriff’s office.

Two 17-year-old boys and Wydur apparently entered the construction site and started up the piece of equipment. Police said the teens may have been drinking.

Wydur’s parents said the keys to the machine were in the ignition and that the construction site was not fenced in.

Ed and Rachel Wydur said it was a moment of bad judgment.

"They were just boys out looking to have a good time. Not causing trouble, not vandalize things,” said Rachel.

Justin had just graduated from high school and his parents said he was a good boy who liked to ride off-road vehicles and hunt.

Work had been stalled at the construction site because of bad weather and the heavy equipment was left behind, reported KIRO 7 Eyewitness News.

KIRO 7 called the property owner, Horizon, to ask why the keys were still in the ignition. The person did not want to comment.

Police said the case will be referred to the prosecutor’s office for possible trespass and illegal use of equipment charges.
