COQUILLE — Peter Shianna, 43, will remain in the Coos County jail after a judge denied his release during a hearing on Thursday. He is charged with rape and two counts of sexual abuse relating to an incident that is alleged to have occurred on Christmas Eve in 2007.

Chief Deputy District Attorney Mark Monson said a woman reported being raped that night, behind the Fred Meyer store in Coos Bay. Unfortunately, she could not identify her assailant, whom she said she had met on a bus ride to Coos Bay.

Monson says that she was waiting to be picked up by family at the time and, after telling them what happened, she was taken to the hospital. The victim was treated and had a Safe Sexual Assault exam performed, with the suspect’s DNA collected and analyzed.

The case, unfortunately, did not go any further that that for more than five years. Then the forensic lab in Oregon contacted Coos Bay Police Detective Eric Schwenninger last year to let police know that they had gotten a hit on that DNA from an inmate in the California prison system.

Shianna was serving time for a similar offense, Monson said, when the testing pinged back to Oregon. A warrant was issued for his arrest, which also served as a detainer to keep the suspect from being released out of the system.

He then waived extradition and was brought back to Coos Bay.

Monson says Shianna admitted to investigators that he had sex with the woman, but is arguing that it was consensual.

The alleged victim is planning to testify at trial, and did testify before the grand jury before it returned the indictment against Shianna.

The charges are all Measure 11 crimes. If convicted on the rape charge he faces a minimum sentence of 100 months in prison, and a minimum of 75 months for the sex abuse charges.

Shianna is due back in court for a change of plea hearing at 8:30 a.m. April 2.
