Darryl Lamar Gartley walked the 15-year-old girl to school. He also accompanied the teen to her meetings with her juvenile probation officer in Washington County.

Gartley, who was 20 years old at the time, was the girl’s pimp.

On Tuesday, Gartley was sentenced to 12 years and five months in federal prison for trafficking the teenager and another underage girl in Oregon after he was convicted of similar charges in California with other girls.

He posted photos of the two Oregon girls on Craigslist and Backpage in 2016, describing them as “honey” and “luscious,’’ and emailed pornographic images of each to potential customers, according to prosecutors.

Gartley met the 15-year-old girl from Oregon on Facebook using a fake name and moved in with her less than a month later. Her mother was apparently unaware that Gartley was sex-trafficking her daughter, prosecutors said.

The 15-year-old girl befriended another 15-year-old girl through her juvenile probation counseling and that new friend also became a victim of sex-trafficking by Gartley, investigators say.

“His systematic and repeated exploitation and abuse of minors — truly reprehensible conduct deserving of the Court’s strongest condemnation — requires a lengthy period of incarceration to both protect the public and provide an adequate quantum of punishment,’’ federal prosecutors Ravi Sinha and Kaylynn N. Foulon wrote in a sentencing memo.

Darryl Lamar Gartley, 23, was sentenced to 12 years and five months in federal prison for the sex trafficking of two 15-year-old girls in Oregon.

In January 2017, Gartley was arrested in California and subsequently convicted in San Diego Superior Court of human trafficking of minors and pimping for prostitution. A review of his cellphone indicated Gartley had sex-trafficked girls in Oregon as well, leading to the Oregon investigation.

On Tuesday, U.S. District Judge Michael H. Simon ordered Gartley, now 23, to face a lifetime of supervision upon his release from prison.

He also ordered nearly 30 conditions of supervision, including that Gartley undergo sex offender treatment, polygraph tests, have no contact with his victims and any gang members or prostitutes, not frequent hotels and have no contact with anyone under age 18, excluding his own children, without prior approval of his probation officer.
