A man was hospitalized late Saturday night when an attempt to slide across the hood of a car stopped at a red light sparked a physical altercation near the corner of 13th Avenue and Alder Street. Witnesses say the car’s driver and passenger assailed the man, knocking him out with one punch in the parking lot of the 7-11 near the University of Oregon campus.

The victim was walking east from Max’s Tavern when he spotted the white BMW sedan just outside Dairy Queen at approximately 2:20 a.m. That’s when he decided to jump onto the car’s hood and slide across it.

The driver and passenger got out and confronted the man, who was walking alongside a group leaving Max’s after closing. Members of the group intervened in order to calm the passenger and driver down.

“We told them that he was drunk and that they should leave him alone,” Delaney Butler said.

The driver and passenger returned to the vehicle after the intervention and the man continued east on 13th toward campus. When the victim reached 7-11, the BMW had pulled up in front of Peachwave and the assailants resumed the confrontation.

An Emerald columnist was the only witness. Matt Halpin saw the driver of the BMW approach the victim and punch him, rendering the man unconscious. The driver and passenger returned to the car and sped off while Halpin and Opinion Editor Andrea Harvey called the police.

Butler and a friend arrived shortly after.

Paramedics responded and took the victim to Sacred Heart Medical Center before Eugene Police officers arrived at the scene.

The officers confirmed that they’re searching for the car and the alleged assailants. If found, the two may face assault charges.

This is the second violent altercation to occur at the corner of 13th and Alder over the weekend. Lee Ulbricht was arrested and charged with criminal mischief, physical harassment, disorderly conduct and damaging a vehicle on Friday night after an argument during a freestyle rapping competition turned violent.
