A Washington County Circuit Court jury on Friday found Portland activist Micah Rhodes guilty of second-degree sexual abuse of an underage girl.

The jury's 10-2 verdict came after a 1.5-day trial. Rhodes, once a prominent organizer of Portland's Resistance, is now 24.

He was 20 at the time he had sex with the girl in January 2014. Her age isn't listed in court papers, but investigators said she was younger than 18 then and unable to consent because of her age.

Rhodes will be sentenced in May. Oregon sentencing guidelines recommend a prison sentence ranging from about two to two-and-a-half years, said Deputy District Attorney Andy Pulver, who tried the case.

He could face as many as five years in prison if the prosecution successfully argues that Rhodes' felony was particularly egregious. Judge Janelle Wipper also could decide to give him probation.

Rhodes was frequently seen at marches and sitting in on meetings at Portland City Hall. He also was a leader of Portland's Resistance, a group that formed after Donald Trump won the presidential election in November 2016. He helped organize people during night after night of protests immediately after Trump's victory.

He was charged in the Washington County in February 2017.

He is scheduled next week to go to trial in Multnomah County Circuit Court in a separate case.

Rhodes faces accusations that he had sexual contact with a 17-year-old boy when Rhodes was 20 or 21 in Gresham and in Troutdale.

Court papers say Rhodes met the boy on a gay dating app and that the boy wasn't able to consent because of his age.

Rhodes faces four counts of second-degree sexual abuse and one count of third-degree sexual abuse.

Rhodes was on supervision by the Oregon Youth Authority for sexual abuse and sodomy at the time he was charged for alleged abuse in both counties, authorities say. Juvenile records aren't public, so details of the earlier case aren't available.

Rhodes had been required to register as a sex offender at the time he was charged in the Multnomah and Washington county cases.
