PORTLAND, Ore. (KOIN) — A Washington County man was convicted of sex crimes after he and his roommate raped a 14-year-old girl.

The Washington County District Attorney’s Office said Muizz Sosna and his roommate and co-defendant, John Wirtz, met the girl through social media. Wirtz invited her over for sex and both of them raped her.

After raping the girl, they wouldn’t let her leave and Sosna threatened her with a handgun, the DA’s office said.

When she finally escaped, she flagged down a USPS mail carrier, who called for help.

Sosna and Wirtz were arrested.

Sosna’s case was heard by a jury, who convicted him of 2nd-degree sexual abuse, 3rd degree rape, menacing and unlawful use of a weapon.

Deputy DA Allison Brown pushed for a length prison sentence due the victim’s vulnerability, but Sosna was sentenced to two years.

On July 5, 2018, Wirtz pleaded guilty to 2nd-degree sexual abuse and 3rd-degree rape.
