PORTLAND, Ore. (KOIN) — A 30-year-old man was fighting for his life in a hospital on Thursday, days after being found unconscious on the side of a road in Gresham — the apparent victim of a hit-and-run.

John McDonald was found Saturday evening near Southeast 215th and Stark Street, according to the Gresham Police Department.

Authorities said his injuries were consistent with being hit by a vehicle.

He was under a medically-induced coma Thursday night at OHSU. His family members told KOIN 6 News they hope whoever is responsible for his injuries is brought to justice.

“It’s really sad because that’s our family, you know? And it feels like, to me, somebody left him for dead — left him on the side of the road like roadkill,” said McDonald’s cousin, Ashley Woods.

Woods said McDonald had his whole life ahead of him but is now tied to life support machines in a hospital bed, fighting for his life. She said her cousin has brain damage along with multiple fractures in his arm, elbow and leg.

“The doctors say it looks like a hit-and-run so that’s what we are going with because there is so much damage,” she said. “But we are unsure because he was living on the streets at the time he is homeless.”

Woods said that although her cousin has been homeless off and on for 10 years, he may have been making his way to his mom’s house in the area. She said whoever called for help after finding him, no one was there when the ambulance arrived.

“It was raining that night really, really bad that Saturday night. It was really cold outside, so we know he suffered,” she said. “We don’t know how long he laid there until somebody found him.”

Woods hopes the person who called for help comes forward. She’s also asking members of the public to think back to whether-or-not they’d seen McDonald on the day he was hurt.

“Somebody has to know something,” she said. “I know people in Downtown Portland know who he is. I know they know who John is.”

Police want to hear from any possible witnesses. Anyone who may have driven through the area where the man was hit at around 7:30 p.m. on Feb. 15 is asked to call the police tip line at 503.618.2719.
