PORTLAND, Ore. (KOIN) — A man suspected in a November 2020 sexual assault was indicted on 35 charges for other sexual assaults and crimes that happened in February 2021, the Multnomah County DA’s Office said Wednesday.

Johnel Johnson was arrested March 1 in the 3700 block of Southeast 166th Avenue after an investigation began in February. Allegedly, the 32-year-old used a gun and knife to kidnap, rob and sexually assault someone, then forced that person into prostitution along with physical assaults.

While that investigation was underway, investigators said they connected Johnson to the November sex assault with a similar tactic: a knife to kidnap, rob and sexually assault someone, then forced that person into prostitution.

“This is an extremely traumatic event and we want to make sure that we’re trauma-informed and do what is right by those victims,” said Senior Deputy DA J.R. Ujifusa, who supervises the office’s Human Trafficking Unit.

The 35 counts from the grand jury indictment are spread out among these charges: Rape, assault, sodomy with a gun, compelling prostitution, promoting prostitution, felon with a firearm, strangulation, kidnapping, robbery, sex abuse and unlawful use of a weapon.

Johnson, 5-feet-7 and 215 pounds, is currently being held in the Multnomah County Jail. No bail was listed.

The investigation continues. Anyone with information is asked to contact PPB Detective Kyffin Marcum at 503.823.0462 or Detective Scott McCollister at 503.823.0424.

“We believe there may be more victims because there’s a pattern that we’re seeing in the investigation and the length of time between November and February opens up the possibility that other individuals may have been victimized by this individual,” Ujifusa said.

If there are other victims, the DA’s office wants them to come forward to both talk with police and prosecutors and to get the help they need.

“I hope that they feel that they are comfortable coming forward and talking to law enforcement and coming and talking to a prosecutor and getting an understanding of what it looks like to come forward,” Ujifusa said, “but also for the ability to hold someone accountable and also to move forward in their lives, to deal with the trauma.”

Other victims can reach the DA’s Human Trafficking Unit by calling 503.988.3162, or by calling the PPB Sex Crimes Unit, either through 503.823.3333 or 503.823.0400
