A Multnomah County jury on Monday found 30‑year‑old Isaac Cortez Bynum Jr. guilty of second‑degree murder after prosecutors said he fired 13 shots into a vehicle in August 2021, killing a 17‑year‑old boy. Jurors also convicted him on unlawful‑use and felon‑in‑possession weapons charges tied to separate incidents. Bynum is scheduled to be sentenced July 24, 2026.
The Verdict And Charges
According to reporting by KOIN, jurors found Bynum guilty of second‑degree murder and unlawful use of a weapon after the state said he opened fire into a vehicle on Aug. 24, 2021. Prosecutors told the jury the victim, 17‑year‑old Seneca Alexander Jr., was struck multiple times and later died.
The same case also folded in earlier weapons allegations. The jury returned guilty verdicts on two counts of felon in possession of a firearm tied to separate incidents that were handled alongside the murder charge, KOIN reported.
Court Docket And What Comes Next
Multnomah County court records list the criminal case under number 21CR52757, with Deputy District Attorney Eric Palmer assigned as prosecutor, according to the county’s Multnomah County District Attorney online docket.
The docket shows the matter set in Multnomah County Circuit Court at the Multnomah County Central Courthouse as it moves toward Bynum’s sentencing date in July 2026.
How The Shooting Unfolded
Local coverage and public records indicate the first reports of gunfire came in near Gresham High School on Aug. 24, 2021. Alexander was later found with multiple gunshot wounds and died at a hospital, according to earlier reporting by KPTV.
Gresham Police and the East Multnomah County Major Crimes Team responded to the area, processed the scene and followed leads that investigators say eventually supported the arrest warrants and prosecution that led to this week’s guilty verdicts.
Legal Implications
Under Oregon law, a conviction for second‑degree murder carries a lengthy prison term. Bynum’s formal sentencing is set for July 24, 2026, when a judge will weigh the murder count alongside the unlawful‑use and felon‑in‑possession convictions in deciding his punishment, according to KOIN.
Wider Context
Alexander’s killing came during a period when Portland‑area homicides surged to multi‑year highs in 2021 and 2022, according to data compiled by The Oregonian/OregonLive. The spike in shootings has repeatedly put families like Alexander’s at the center of public conversations about how the region responds to gun violence.
Relatives and community advocates have called for more prevention work along with consistent follow‑through on investigations. In earlier coverage from KPTV, Alexander’s father publicly pleaded for help tracking down those responsible and pushed for more resources to confront shootings in the area.
Sentencing in Bynum’s case is scheduled for July 24, 2026, in Multnomah County Circuit Court. This story will be updated if prosecutors, Gresham Police or Alexander’s family release new statements as the case moves toward that hearing.
