King County prosecutors claim Louis Henry Abalos met the then-17-year-old girl while recruiting out of Woodinville in 2012. Abalos, now 33, is alleged to have coerced the girl into touching him sexually.
Abalos has been charged with first-degree sexual misconduct with a minor, a felony count usually filed against teachers or pastors who take up with the older teens in their care.
Writing the court, Senior Deputy Prosecutor Carla Carlstrom said Abalos abused the trust placed in him by the Marine Corps and the wider community.
"As a military recruiter, the defendant is in a position of power and control over a prospective recruit's or candidate's potential career," Carlstrom said in charging papers.
Abalos "abused his position of power," the prosecutor continued. The girl "was concerned if she did not go along with the sexual contact that the defendant would be able to prevent her from making it into the Marines."
The girl came forward with the allegations in late 2012, bringing them to staff at her high school. School officials subsequently contacted the King County Sheriff's Office, which investigated the claims.
According to charging papers, the girl told detectives she first met Abalos when she contacted the Marines about enlisting two months before.
During a visit to the Woodinville recruitment office, Abalos touched the girl inappropriately during a physical test, lifted her onto his lap and fondled her before persuading her to touch his genitals, a Sheriff's Office sergeant said in charging papers. It was their second meeting.
The following month, Abalos was driving the girl home from an event when he again got her to touch him sexually, the sergeant said in court papers, recounting the girl's account.
The girl "was afraid if she did not do it that she would not get a position in the Marines," she told the court. During another recruitment session, the sergeant continued, Abalos had sex with the girl.
A teacher noticed the girl appeared to be in distress and asked her what was wrong. The girl then made the allegations.
Interviewed by investigators, Abalos, a Renton resident, denied any wrongdoing. He does not appear to have been jailed.
