Gregory R. Walker Biography Gregory R. Walker Wiki
A 39-year-old man made his first appearance Tuesday in Multnomah County Circuit Court for the death of another man during an altercation under a North Portland freeway overpass in April.
Gregory R. Walker has been charged with first and second degree murder in the death of Robert M. Chambers, according to court documents, as well as first degree larceny and possession of a stolen vehicle.
The two murder charges relate to the death of Chambers, 59, who died in hospital on April 11 after police found Chambers shot dead near North Cook Street and Gantenbein Avenue around 10 p.m. tonight.

Residents of an adjacent camp previously told The Oregonian/OregonLive that the shooting took place after a man living under the freeway overpass fought over a truck.
Walker wore a jail suit and said nothing during the summons to the Multnomah County Justice Center. He remains in custody and is expected to appear in court on August 1.
“It’s just devastating,” Chambers’ sister told District Judge Benjamin Johnston in a remote appearance. “I just wish that never happened.”
Walker was held for two days after the shooting, but was not charged with the murder until Friday, according to a court document.
On April 13, police arrested him in a stolen Subaru Outback with a loaded pistol, nearly 200 rounds and a catalytic converter in the back seat, according to court documents. Later that month, Walker attempted to hang himself at the Downtown County Jail and was charged with blowing his head off and spitting at several officers after the attempt, records show.
Police arrested him in August 2021 for breaking and entering a house on North Winchell Street, according to an affidavit. Walker also has a lengthy criminal record in his hometown of Michigan, including charges of domestic violence, willful destruction of property and assault.
Chambers’ last listed address was at an affordable condo complex two blocks from the filming location, and the 59-year-old also had significant Michigan ties, though it’s unclear if the two knew each other.
In a previous arrest last year, Walker told prison guards he used methamphetamine daily and lived on the streets of Portland for about a year after becoming homeless during the pandemic.
