PORTLAND, Ore. (KOIN) — A 20-year-old Portlander is in the Multnomah County jail after allegedly robbing three people and pistol-whipping a woman shortly after midnight Saturday morning.

A Portland police sergeant was flagged down by people near SW 14th and Taylor around 12:35 a.m. and found one person shot in the leg. The victims told police two people were involved.

“He was bleeding pretty bad. There was some concern about his welfare because of the wound and so the sergeant was able to get a tourniquet, get it on the leg to help control bleeding,” PPB Sgt. Kevin Allen told KOIN 6 News.

Officials said the sergeant alerted officers to a man and woman running from the scene, and within minutes those people were stopped by police.

“Within four or five minutes they were able to get two people into custody, one of which was confirmed to be involved. The other one was not was later released.”

Detectives arrived to help with the investigation, police said, and later arrested Jayda Z. Wise (also known as Demarion Z. Wise.) Wise was booked for first-degree assault and three counts of first-degree robbery.

The second suspect, a man, is still being sought.

The shooting victim, 28, was taken by ambulance to a hospital for treatment and is expected to recover. The woman who was pistol-whipped, 35, declined to be taken to the hospital. The third person, 46, suffered a scraped neck that officials said may have been from shrapnel.

“It is it certainly is an unusual and terrifying experience,” Allen said.

The case remains open and under investigation. Anyone with information is asked to call Portland police.
