MILWAUKIE, Ore. -- A Milwaukie man hopes the public can help track down the driver who attacked him with a hatchet.

“I have never felt so helpless in my entire life,” said Sean Van Walchren.

Van Walchren says he was driving from Milwaukie to Portland Wednesday morning when another driver in a dark gray Mazda 3 cut him off. Van Walchren honked his horn.

“I didn’t scream, yell, or flip off,” he said.

Van Walchren says at the stoplight at Southeast McLoughlin Boulevard and Harrison Street, the other driver got out of his car with a hatchet.

“Proceeded to bash the driver side window open,” said Van Walchren. “The glass instantly shattered.”

The situation only worsened. Van Walchren says the irate driver turned to the windshield and continued swinging.

“I thought this might be the end,” he said. “This may be how my story ends.”

Van Walchren says he had nowhere to go. He was boxed in.

“I could literally do nothing but sit there and hope this guy doesn’t kill me," he said.

Van Walchren says the man eventually let up and took off. He is hoping officers can track him down.

“It’s not like I want him to live the rest of his life in prison,” he said. “I just don’t want this to happen to anybody else.”

The attacker was described as a white man in his late 30s or early 40s with thinning hair and baggy clothes. Anyone with information about the case is urged to contact the Milwaukie Police Department.
